4993-E P-(i)SAFETY PRECAUTIONS

SAFETY PRECAUTIONSThe machine is equipped with safety devices which serve to protect personnel and the machine itself fromhazards arising from unforeseen accidents. However, operators must not rely exclusively on these safetydevices: they must also become fully familiar with the safety guidelines presented below to ensure accident-free operation.This instruction manual and the warning signs attached to the machine cover only those hazards whichOkuma can predict. Be aware that they do not cover all possible hazards.

1. Moving and Installing the Machine• There are two methods of moving the machine to any desired location; lifting the machine with

the attached lifting hooks and pushing the machine on rollers.

Precautions for Lifting:a. Use the wire rope of 20 mm (0.79 in.) or over in diameter.

b. Check the wire rope angles so that the ropes do not interfere with the machine.(Do not slant the machine more than 40 degrees from the vertical.)

c. Lift the machine carefully while balancing the machine.

d. When placing the machine on the floor, lower the machine slowly using care not to giveshocks to the machine.

(Machine weight including hydraulic unit, control cabinet, and NC unit)

Precautions for Rollinga. Do not tip over or hit the machine against the ground.

• When selecting the machine installation site, ensure that the following conditions are met.If not, it may be difficult to perform safe operation or maintain the guaranteed accuracy.

a. The machine ambient temperature is within the range from 5 to 40°C.

b. The machine ambient humidity is within the range from 40 to 75% at 20°C and no conden-sation is allowed.

c. Avoid installation near the factory door because the machine is subject to rapid tempera-ture change by warm or cool air blowing against the machine.

d. Also avoid installation in a place which is subject to direct sunlight.

e. For the installation ground conditions, refer to Section 2 “Transportation and Installation(Relocation).”

4993-E P-(ii)SAFETY PRECAUTIONS

f. To maintain the guaranteed accuracy, you are advised to care and control the factory tem-perature.

• Prepare a primary power supply that complies with the following requirements.

a. Primary power voltage 200 V

b. Voltage fluctuation ±10% max.

c. Power supply frequency 50/60 Hz

d. Do not draw the primary power from a distribution panel that also supplies power to a largenoise source (such as an electric welder or an electric discharge machine). Doing so couldcause malfunction of the NC unit.

e. The law stipulates that machine tools must be grounded (by Class-D grounding work).When requesting an electrician for construction work of electric facilities, instruct the elec-trician to perform Class-D grounding work based on the technical standard for electric facil-ities.If the machine is not connected with a ground, insulation failure may cause the leaked cur-rent to flow into a human body, resulting in serious injury involving death.

f. Connect the machine to the ground using an individual cable. If there is no choice but touse a common grounding cable, avoid shared use with the equipment that generates alarge amount of noise (such as an electric welder or an electric discharge machine).

2. Before Turning on the Power• Make sure that the doors to the operation panel and the electric control cabinet are closed.

• Make sure that there are no obstacles around the machine.

• Turn on the main power disconnect switch before turning on the CONTROL on the operationpanel.

3. Chuck Precautions• Always close the front shield before starting the spindle or cutting operations.

• Always observe the spindle speed maximums for the installed chuck.Never run the spindle exceeding the maximum allowable chuck speed.

• If a chuck or fixture is unique to your application, check the maximum allowable spindle speedand stay within the limit. Also, take note of the workpiece gripping force and balance.

• The maximum spindle speed can be limited by inputting a G50 command with the spindlespeed. The G50 command helps to ensure safety in operation.

Recommended temperature change for 24 hours: : Within ±2°CTemperature difference between the measurement near the floor and the measurement at a position 3 m high from the floor

: Within ±1°C

4993-E P-(iii)SAFETY PRECAUTIONS

• If the spindle must be rotated close to the maximum allowable chuck speed, observe the follow-ing points:The maximum allowable spindle speed and application pressure are indicated on the nameplate on the front shield and on the chuck body. The allowable maximum speed and the applica-ble pressure ensure a chucking force that is more than one-third over the original chuck grip-ping force with the standard soft-top jaw set in line with the periphery of the chuck body.

a. Make sure that the workpiece clamped in the chuck is balanced.

b. Apply the allowable maximum amount of pressure to grip the workpiece because centrifu-gal force reduces the chuck gripping force.

• If special jaws (larger than standard soft-top jaws) are used, observe the following points:

a. Lower the spindle speed because centrifugal force and lower efficiency reduce the chuckgripping force.

b. If the jaw tightening nut (jaw nut) is outside of the periphery of the chuck, only one tighten-ing bolt is holding the jaws in place. This is a potentially dangerous condition. Jaw nutsmust always be within the periphery of the chuck.

c. Machine the jaws to the workpiece shape.

• Securely tighten the bolts on the chuck body, the jaws, and the block to the specified torque.Use lubrication oil. Make sure that the torque is at least 392 to 490 N (88 to 110 lbf).

4. General Checks• Check the amount of lubricating oil every day before starting operation.

• Always use the specified brand of lubricating oil.

• Use the recommended type of cutting fluid (coolant) when possible.

• It is recommended to use a water-soluble coolant to prevent fire. Do not attempt unmannedoperation if a non-soluble coolant is used.

• Change and replenish the lubricating oil and coolant in each reservoir according to the sched-ules in the manual.

• Clean the filters according to the schedules in the manual.

• Make sure that each pressure gauge on the air and hydraulic lines display the correct value asdescribed in this manual.

• Always turn off the power before beginning any work inside the front shield. In addition, turn offthe power before beginning work at the back of the machine that requires an operator to enterthe machine operating zone.

4993-E P-(iv)SAFETY PRECAUTIONS

5. Before Starting Operation• Always follow the instructions in the operation manual.

• Always make sure that all of the protective covers including the front door and the chuck coverare in place before operating the machine.

• Always close the front shield before starting operation.

• Never attempt to run a new program without checking its operation. Run the program without aworkpiece set in the chuck and make sure that there is no interference. After making sure thatthe program has no bugs, cut a workpiece in the single block mode. If no problems are discov-ered, automatic operation may be started.

• Before attempting the following operations, make sure that they can be accomplished safety.

a. Spindle rotation

b. Turret indexing

c. Axis movement

• Never touch chips or the workpiece while the spindle is rotating.

• Never attempt to stop a moving object by hand or with a tool.

• Check the jaw installation conditions, the hydraulic pressure, and the maximum allowable spin-dle speed for the power chuck.

• Check the installation and arrangement of the tools.

• Check the tool offset settings.

• Check the zero offset settings.

• Make sure that the spindle speed and feedrate override settings are at 100%.

• Before feeding the turret, check the software limit setting positions for both the X- and Z- axes.

• Check the turret index/rotation position.

• Check the tailstock body position.

• Make sure the cutting operation is within the allowable transmission power and torque ranges.

• Make sure that the workpiece securely fitted in the chuck or fixture.

• Check the cutting fluid nozzle positions. They must be set to properly supply cutting fluid to theappropriate points.

4993-E P-(v)SAFETY PRECAUTIONS

6. Precautions against Fire• Selecting Coolant

Use nonflammable coolant.a. Never use oil coolant because it could catch fire from heated chips, tool’s frictional heat, or

grinding spark.

When using oil coolant for unavoidable reason, observe the following:a. Check the tool edge condition, tool life, and set the cutting conditions that never cause fire

before you start machining.

b. Clean the coolant filter at regular intervals to maintain sufficient coolant discharge, andalways check the coolant for normal discharge.

c. Take every measures so that you can extinguish the fire immediately by placing a fire extin-guisher near the machine and have an operator always watch the machining condition, orinstalling an auto extinguisher.

d. Do not place any flammable objects near the machine.

e. Dispose of chips not to allow them to stack.

f. Periodically clean the inside and surrounding of the machine while checking that all thedevices are normally operating.

g. Never attempt untended operation.

h. When using oil coolant for grinding, you are requested to install fire-fighting equipmentsuch as auto extinguisher. In this case, inform us of your intention in the stage of examiningyour facility.

• When machining flammable material

a. Before machining any of the flammable solid materials such as resin, rubber, or wood,carefully study and understand the material characteristics and observe the above precau-tions to take all possible measures to prevent fire.

b. Use particular care when machining magnesium, because its chips react to the water-solu-ble coolant and generate hydrogen. The hydrogen may catch fire from burnt chips, result-ing in explosive fire.

• Performing Dry Machining

a. Dry machining is a fire hazard because workpiece, tool, or chips are not cooled. Therefore,never place any flammable objects near the machine and dispose of chips not to allowthem to stack.

b. Take the same safety measures as in the case of using oil coolant described above, suchas checking the tool edge state and tool life, and setting cutting conditions that never causefire.

• Emergency Measures in Door-close and Power-OFF State

a. Should fire break out in the machine when the door is closed and the power is OFF, openthe door using the door lock switch release key and extinguish the fire.(For details, refer to “Safety door switch” in Section 3. Interlock.)

4993-E P-(vi)SAFETY PRECAUTIONS

7. Setup• Make sure that setup is complete.

• If the setup is changed, operate the machine step-by-step to make sure that cutting can be per-formed without any problems.

• Before changing the chuck and/or chuck jaws, make sure that the chuck fits the intended job.

• If two or more workers must work together, establish signals so that they can communicate (forexample, when lifting or setting heavy objects). Each worker should be aware when a new pro-cess is about to begin.

• Use the crane or equivalent tool to handle heavy objects.

• When attempting an unfamiliar setup, recheck the setup before beginning operation.

• Remove unnecessary toolholders from the turret.

• Ensure that the bolts for fixing the toolholders to the turret are securely tightened.

• Remove the bolts which are not used for fixing the toolholders.

8. Workpiece Loading and Unloading• Make sure that workpieces are loaded and unloaded securely.

• Before loading or unloading a workpiece, retract the turret so that the cutting tools in the turretcannot injure the operator.

• Before loading and unloading a workpiece, make sure that the spindle has come to a completestop.

• Before running a new program, rotate the spindle to make sure that the workpiece is securelyclamped in the chuck.

• Before machining an irregularly-shaped workpiece, make sure that it is balanced properly.

• When handling heavy workpieces, use the a crane, hoist, or other similar tool.

• Before loading a workpiece, make sure that the workpiece has a portion that can be used forproper chucking.

9. At the End of the Day• Clean the machine.

• Move the turret to the predetermined retraction position.

• Turn off the CONTROL, before turning off the main power disconnect switch.

• Make sure all power switches are turned off.

4993-E P-8SECTION 2 TRANSPORTATION AND INSTALLATION (RELOCATION)

SECTION 2 TRANSPORTATION AND INSTALLATION (RELOCATION)

1. Site Selection GuidelinesIn order to ensure high machine accuracy and performance, the following points should be consid-ered with regard to the installation site.

(1) Foundation work is advised for sites where the subsoil is soft, to prevent the machine from tilt-ing or sinking after installation.For details regarding foundations, refer to 2. “Foundation Dependant of Ground Condition” inthis section.

(2) The installation site should be as far as possible from vibration sources such as roads, stamp-ing/press equipment, or planer machine tools.If nearby sources of vibration are unavoidable, prepare dampening pits around foundation toreduce the vibration effects.

(3) NC malfunctions could result from the proximity of high-frequency power generators, electricdischarge machines, and electric welding machines, or when power is supplied from the samedistributor panel as these machines.For wiring details, consult our service engineer dispatched to assist with installation.

(4) The ideal operating environment calls for an ambient temperature of 20°C, with humiditybetween 40 and 75%.

(5) Keeping the ambient temperature at a constant level is an essential factor for accurate machin-ing.

(6) In order to maintain static machine accuracy within guaranteed values, the machine installationsite should be located so that it is unaffected by air currents within the factory.Although air-conditioning is not required, the optimal ambient temperature range it 17°C to25°C

(7) To maintain static machine accuracy at levels even higher than the standard guaranteed values:

a) Keep the ambient temperature variance for 24 hours (1 day) within ±2°C.b) Ambient temperature variances from floor level to a height of about 5 meters should be held

within 1°C.


1-1. Care in Machine Transportation

This machine integrates hydraulic unit, control cabinet, and NC unit into one construction instead ofhaving them as separate units, and so the machine can be easily moved or transported.There are two different methods for moving the entire machine to any desired location; by an over-head crane, using lifting hooks supplied together with the machine and by rolls over which themachine is pushed by manual labor.

Lifting the Machine

LE11137R0500400020001

Procedure :

1- Locate the upper saddle to the left-hand end of travel (negative stroke limit position of Z-axis).For two-turret models, locate the lower turret to the left-hand end of travel (negative strokelimit position of Z-axis).When the machine is equipped with the tailstock, position the tailstock at the far right endposition.Turn off power supply to the machine.

2- Remove the headstock LH side cover (A) and the headstock front cover (C), and fix the liftinghooks at three positions. At the tailstock side, the chip falling gap on the bed is used for liftingthe machine.

3- Move the front sliding cover (chip guard) (D) to the position where cables will not interferewith it when they are hooked around the lifting hooks (E).Place protective pad between the headstock and the cable hooked around the hook at theheadstock front.

Now the machine is ready to be lifted.


Precautions for Lifting

WARNING

Rolling

CAUTION

2. Foundation Requirements

2-1. Precautions for Foundation Work

SAFETY INSTRUCTIONS

• The cables should have a nominal diameter of 20 mm (0.79 in.) or larger.• Change an angle formed by each cable line so that the cables will not contact the fin-

ished surfaces of the machine.(Do not tilt any wire rope exceeding 40 degrees away from the vertical direction.)

• Check for balance and be very careful when lifting the machine.• Use extra care to lower the machine gently onto the floor; NEVER APPLY SHOCKS TO

THE MACHINE WHEN PLACING IT ON THE FLOOR.Approximate Weight of Machine 1ST1750B1520,700 kg (45,540 lb) B2222,900 kg (50,380 lb) 2SC1750B1523,300 kg (51,260 lb) B2222,500 kg (56,100 lb) 2ST750B0816,400 kg (36,080 lb) 2ST1750B0818,700 kg (41,140 lb) (Including the hydraulic power unit, the electrical control box and CNC unit.)

Be careful that the machine does not tip over on any side so that the machine base maynot strike the ground.Fix the front door and the doors to the operation panel before rolling the machine.

With a solid ground, a concrete floor about 200 mm (7.87 in.) thick and no gaps betweenground and floor, foundation work or anchoring is not required. The structural rigidity ofthe machine permits normal machining.For long-maintained accuracy and where sub-soil or ground under the floor is not strongenough, a new concrete foundation should be set up in accordance with the FoundationPlan in this section.

• Foundation requirements vary depending on the characteristics of the sub-soil. Underany soil conditions, it is important that sub-soil should be well compacted to keep thefoundation from unsettling once the machine has been installed.

• Where sub-soil is too soft, it is necessary to drive concrete piles into the sub-soil.• The Foundation Plan attached to this Manual is prepared for laying a typical concrete

foundation specifically for the machine. The concrete thickness or depth should bedetermined in terms of the ground condition in each case.


3. General Procedure for Installation

3-1. Installation Procedure

Procedure :

1- Place leveling plates, 200 mm × 200 mm × 20 mm (7.87 × 7.87 × 0.79 in.) over individualfoundation bolt-holes. Refer to the Foundation Plan.

2- Place foundation washers (furnished together with the machine) on the leveling plates andthen place the machine on them.

3- Pass foundation bolts through the hole in the leveling plate and a center bore through thebuilt-in jack screw assembly.Secure each foundation bolt carefully, using a washer and a nut on its upper end.

4- Use wedge pieces, shims, or leveling blocks under the machine base to level the machineapproximately.

5- Pour mortar into the foundation bolt holes and allow it to set.

6- After the mixture has become hard enough, remove the shims or leveling blocks from underthe machine base, and level the machine within the specified limits.

3-2. Precautions for Installation

• Keep the underside of the leveling plates free from any oily substance.

• With leveling jack screws resting on foundation washers, the bottom surfaces of the machinebase casting should be about 20 mm (0.79 in.) above concrete floor level.

• Fill the foundation bolt holes with mortar so as to reach the underside of the respective levelingplates. Be sure to compact the mortar thoroughly.

CAUTION

LE11137R0500400100001

Procedure :

1- Connect the AC voltmeter to the spindle drive motor control unit or the machine power termi-nal as shown in the above figure.

2- Measure the voltage (V0) applied to the spindle drive motor at a standstill.

3- Measure the maximum voltage (V1) during deceleration of the spindle drive motor.

4- Calculate the instantaneous voltage regulation by the following formula:Instantaneous voltage regulation = (V1 - V0) / V0

1) Connect the ground wire to the external protective earth terminal (PE) in the controlbox.

2) Do not connect the power cord and the grounding wire in serial; if attempted, it will giveadverse affect to other equipment or cause malfunctioning of the leak breaker, etc.

3) When a leak breaker is used, select the one meeting the following rating.• For inverter circuit use• Sensitive current of 100 mA or more• Middle-sensitivity high-speed inverter type

4) When supplying power to several machines from the same power source, the powersource inductance should be obtained by dividing the value in the above table by thenumber of machines.

5) The inductance of the general KIV cable extended for 50 m (164 ft) is usually 12 µH orso.

6) The instantaneous voltage regulation can be checked by the method illustrated below.As far as the alarm “Voltage regulation too large” is not activated and the instantaneousvoltage regulation is lower than the value in the above table, the power source induc-tance is assumed to be lower than the allowable limit. (The above alarm occurs whenthe power source inductance exceeds the limit.)

7) For further information on instantaneous power regulation and power source induc-tance, please inquire at your Okuma representative.

• The digital AC voltmeter makes a slow response, and therefore the measured valuetends to be a little lower than the actual value. It is recommended to use the analogue ACvoltmeter.

• Shorter deceleration time makes the measurement difficult. Measure the voltage whiledecelerating the motor from the possible highest speed.

• Obtain the instantaneous voltage regulation after ensuring that the alarm “Voltage regu-lation too large” is not activated. This is because the alarm causes the motor control unitto restrict the motor output.

4993-E P-19SECTION 3 OPERATION (OF CNC LATHE)

SECTION 3 OPERATION (OF CNC LATHE)This manual mainly explains the manual operation so that the operator can get used to the machine operationas soon as possible.

1. Before Starting OperationsThis section deals mainly with the operating procedures of your CNC lathe under manual control. Sothe information given here is essential to every operator, whether you are new to a CNC lathe or an“old pro”.Follow these three points:

• Actually operate the CNC lathe by yourself in reference to this Instruction Manual.

• Learn the symbols for the numerical control terms.

• After you have a general idea of how your CNC lathe operates, read this manual repeatedly andalso the Programming Manual.

CAUTION

1-1. NC Operation

Before you begin to operate the machine automatically by tape, make it a rule to check the followingpoints against a process sheet, a program manuscript, or any other chart giving detailed machininginstructions:

(1) Setting of hydraulic power chuck jaws and their gripping pressure

(2) Installation and arrangement of individual cutting tools with respect to their operating sequence

(3) Positioning of tailstock (when the machine is equipped with tailstock)

(4) Setting of tool offsets

(5) Setting of zero offsets

(6) Setting of feedrate override to 100%

(7) Setting of softwired limit positions for each axis

(8) Positioning of the turret to the turret indexing position

All essential information on the setup and check-up procedures for (1) through (3) is described in thesections that follow, and that for (4) through (8) in the Operation Manual for OSP-E100.

Bring the machine to a complete stop by turning off the main switch before operationssuch as setup or adjustments inside the chip guard are carried out.Also turn off the main switch before you attempt to work inside the machine at the rearside of the machine.


1-2. Setting Zero Offsets

What is Zero Offset?

The common coordinate position from which a complete program is made for a particular compo-nent is termed “zero point or program zero”.The program zero is located at the fixed position (center of the spindle) on the X-axis. However, theprogram zero on the Z-axis will vary depending on the setup (incl. chuck, jaws, etc.) as indicatedwith A’ and B’ in the figure below.

LE11137R0500500040001

The operator can establish the reference point for machining (zero point of a program) by enteringX0 and Z0 through the keyboard dimensioned from the fixed zero point of the machine.X0, Z0 is called Zero Offset Values.

The operator can set the reference point of machining(machiningorigin) at any desired point by entering zero offset value Z0.

The NC machining program needsdistance Z as absolute position ofthe tool at A.


Setting Zero Offset Values

There are three possible cases for entering zero offset values:

• Where zero offset values are unknown, as in cutting the first workpiece for instance.

• Where zero offset values are known, as in cutting workpieces of repetitive lots.

• Where the stored offset values are modified.

Explanation for each case is provided in this paragraph with the following example.

LE11137R0500500060001

Case where zero offset value is unknown:

The explanation below is provided with 1 mm (0.04 in.) unit system.To set the zero offset value of Z-axis, proceed as follows.

Procedure :

CAUTION

If the tool offset values are not zero, the zero offset setting procedure will differ from the procedureindicated above.The numeral data entered through the keyboard in the above step “8-” is the sum of “measuredvalue” and “tool offset value”.

LE11137R0500500070011

If the workpiece length is 100 mm (3.94 in.) when it has been cut using a tool with a tool offset of Z =-0.500 mm (0.0197 in.), the position of the tool with a tool offset of Z = 0 is 99.5 mm (3.917 in.) fromthe reference point (program zero).A procedure that does not require a modification of the set zero offset value is described below.

Procedure :

1- Carry out steps “1-” and “2-” as explained before.

2- Enter tool offset data to tool offset #1 register.(Refer to “Setting Tool Offset” in “Data Operation” of OSP Operation Manual.)

3- Cut the end face of the part by moving only the X-axis in the MDI mode with T01 (Tool No.)01 (Tool offset No.) active. (Refer to “Manual Data Input (MDI) Operation” in “Operation” of OSP Operation Manual.)

• Never move the turret in the Z-axis direction until zero offset setting is completed.Keep locating the turret in the position set in the step “1-”.

• For the X-axis, the reference point does not change even when the checking method orsetup changes. Therefore, there is no need to carry out zero offset each time the set upchanges.

• Use a tool with offset values of X = 0, Z = 0, where practicable, for zero offset setting.

2-1. Hydraulic Power Unit

LE11137R0500500100001


Pressure Indication

The pressure gauge is used to indicate the different levels of hydraulic pressure directed to individ-ual functional units on the machine. The selector valve is used to switch the pressure gauge line.

LE11137R0500500110001

Procedure :

1- Match the red paint mark on the knob of the valve with the identification line as shown.

2- Push the valve in.

3- The pressure gauge indicates the setting of oil pressure in the selected pressure line.

To check oil pressure to the disc-type spindle brake, shut off the incoming power supply by turningoff the main switch, and then turn on the main switch again. With only the main switch turned on,proceed with the reading of the pressure gauge as noted above. These steps are required since thepressure gauge can only indicate the working pressure in the selected line for a very short period oftime.

The pressure settings are as follows:Hydraulic power chuck See Item 2-3.Turret index and clamp 3.4 MPa {35 kgf/cm2 (498 psi)} maximumHydraulic spindle brake 1.5 MPa {15 kgf/cm2 (213 psi)}


Adjustment of Hydraulic Pressure

The following outlines the methods of setting individual functional units for operating pressure. Sincethe pressure lines for the turret(s) have been adjusted at our factory before shipment, they will notrequire readjustments, during the initial installation and subsequent normal service of the machine.When readjustment is to be made by your plant personnel, extreme caution must be taken in accor-dance with the instructions given here to avert any mechanical trouble in the drive lines.

• Hydraulic pressure for power chuck. Refer to Item 2-3.

• Turret pressure adjustment (Adjustment is not usually required.)

LE11137R0500500120001

Use the system pressure adjusting valve to adjust the turret pressure since the turret pressureis the same as the system pressure.

• Hydraulic pressure for disc-type spindle brake

2-3. Hydraulic Power Chuck

The construction of hydraulic chuck is shown below.

LE11137R0500500170001

Installation of Hydraulic Chuck

Procedure :

1- Press the CONTROL ON pushbutton switch on the operation panel and step on the CHUCKoperation foot panel. This causes the connecting rod in the spindle bore to move forward.

2- Fasten the connecting rod to the draw screws A.* Use the Allen wrench furnished with the machine.

3- Secure the chuck body onto the spindle end, using mounting bolts B.

4- Adjust the draw screw A so that the outer ends of the master jaws become flush with theperipheral surface of the chuck body when the top jaws are in the OPEN condition.

The individual chuck jaws can be moved in the “opening” direction as the draw screw A is turned inthe counterclockwise direction. Removal of the hydraulic chuck from the spindle is the reverse ofinstallation in steps from “3-” to “2-”.

WARNINGWhen changing parts such as chuck, jaws, or stopper block inside the chip and coolantshield, keep the following in mind:

• Always shut off the source power before changing parts.• Never issue M19 (spindle orientation) or M110 (C-axis joint) command while changing

parts.

Adjustment of Oil Pressure for Hydraulic Chuck

The gripping pressure of the chuck jaws is dependent upon the working pressure of hydraulic fluidwhich is determined by the setting of the pressure adjusting valve installed at the hydraulic unit.A clockwise turn of the valve knob decreases the working oil pressure directed into the chuck cylin-der and counterclockwise turn increases it.The hydraulic chuck pressure can be adjusted with the pressure adjusting valve of the hydraulicunit. Clockwise turn increases the pressure and counterclockwise turn decreases the pressure.Adjust the pressure to a value under the max working pressure of the chuck.

LE11137R0500500190001

Maximum Permissible Spindle Speeds and Oil Pressure Setting

Maximum permissible spindle speed varies depending on types of chuck and cylinder to be used.The allowable chuck rotation speed depends on the chuck and cylinder types. Use the chuck underthe specified max rotation speed.

WARNINGWhen using a chuck, follow the instruction on the name plate at the front cover of themachine.


How to set Maximum Spindle Speed

The maximum spindle speed to which spindle speed is to be limited due to chuck specifications,influence of centrifugal force on chuck gripping force, imbalance of workpiece, etc. can be set byprogram.

LE11137R0500500210001

CAUTION• Whenever the machine has to be operated at a speed as high as its maximum available

chuck RPM, avoid any work running out of balance, and be sure to increase the hydrau-lic working pressure to the maximum allowable pressure limit, because the actual grip-ping force might be reduced with the increase in the spindle speed due to centrifugalforce acting on the chuck jaws.

• The maximum chuck RPM refers to the speed at which the chuck can be turned, with itsgripping force maintained within more than one-third of its rating, while the outer endsof the individual top jaws are positioned evenly with the peripheral surface of the body.Notice that other limiting factors are considered; factors which may be associated withthe overheating of the main drive motor due to frequent starts and stops.

• When soft top jaws larger than standard ones provided with the machine are preparedby the customer and used with the chuck, keep in mind that developing centrifugalforce and decreasing efficiency may reduce the actual gripping force. Be sure toreduce the spindle speed accordingly.

• Where jaw nuts shown below go beyond the peripheral surface of the body, only onebolt secures the corresponding jaw and a very dangerous condition is created. Alwayslocate the jaw nuts within the periphery of the body as shown below. It is a good andsafe practice to use soft top jaws that are made to fit the actual work configuration.

Change of Chuck Gripping Direction - ID/OD Gripping

Gripping direction of the power chuck - ID gripping and OD gripping - can be changed by pressingthe flat key on the operation panel.The change of gripping direction may be made only while the spindle stops.

Greasing

CAUTIONThe chuck has grease nipples either on the chuck front face or on its periphery. Applygrease (Molykote EP grease) to the nipples every day.Since chips and foreign matter accumulate on the jaw moving surfaces on the chuck,clean them every day and lubricate them with the hydraulic oil (HM32, MAS).


2-4. Cutting Soft Top Jaws of Power Chuck

There are three different methods applied in cutting soft top jaws of chuck jaws for chucking a partic-ular lot of parts.

• by pulse feed handwheel

• by tape

• by manual data input (MDI)

They are all basically the same operations, and it is advisable to use the tape or the manual datainput when a good finish on the chucking surfaces of the jaws is essential.Now let’s explain the steps necessary to produce the top jaws for chucking the diameter of 70 mm(2.76 in.) with a depth of 15 mm (0.59 in.) by use of the manual data input.

LE11137R0500500240001

Procedure :

1- Grip a ring of proper diameter in the chuck:φ50 mm (1.97 in.) ring for instance

2- Locate the tool tip point at point A and set the zero offset value so that the actual position ofX-axis is equivalent to the ring diameter; 50 mm (1.97 in.) in this case.Actual Position: X = 50.000 mm (X = 2.0000 in.)

3- Locate the tool tip point at point B and set the zero offset value so that the actual position ofZ-axis is equivalent to the required chucking depth of length; 15 mm (0.59 in.) in this case.Actual Position: Z = 15.000 mm (Z = 0.6000 in.)

2-5. Hydraulic Tailstock Operation(Refer to “6 Tailstock” in SECTION 6.)

The LOC650 is equipped with a programmable tailstock as a standard device.For the programmable tailstock functions, refer to OSP-E100L/E10L Operation Manual and the Pro-grammable Tailstock Function (Two-along Type) in Special Functions Manual.This subsection explains the method of manually moving the tailstock.

Tailstock movement by manual operationWhen moving the tailstock manually, follow the procedure below. The programmable tailstock oper-ation panel is illustrated on the next page.

Procedure :

1- Move the X-axis to the positive variable limit.

2- Move the tailstock sleeve to its retract end and stop the spindle.

3- Press the JOINT POSITION RETURN button on the operation panel. The saddle moves tothe joint position at the rapid traverse.

4- Press the TAILSTOCK UNCLAMP/JOINT ON button. With lighting of the JOINT ON lamp,the tailstock is connected with the saddle and unclamped.

5- Move the tailstock to a desired position by Z-axis feed (100%, 2.4 m/min).

6- For smooth disconnection, move the saddle in reverse direction by half of a backlash (about1 mm).

7- Press the TAILSTOCK CLAMP/JOINT OFF button on the operation panel. The tailstock isdisconnected from the saddle and clamped. Confirm that the JOINT OFF lamp lights.


Setting the Position of Tailstock Body

LE11137R0500500250001

Programmable Tailstock Operation Panel


To set the tailstock position

Procedure :

1- Locate the tailstock body to the position where the tailstock sleeve can support the workpieceend within its travel range (200 mm (8 in.)).

2- Advance the tailstock sleeve to check whether the tailstock body is clamped at a positionadequate to support the workpiece. It is recommended that the protrusion of the tailstocksleeve is kept to a minimum.

To Remove the Center from the Tailstock SleeveUse the center (MT No.6) with the threaded portion.

Advancing/Retracting Tailstock SleeveAdvance and retraction of the tailstock sleeve can be performed by the foot-operated pedal switcheslocated at front of the machine.

LE11137R0500500250002

(1) Left pedal switch (2-step type) is used to advance the sleeve.

(2) Right pedal switch (1-step type) is used to retract the sleeve.

Hydraulic Pressure for Tailstock ThrustTurn the thrust regulating valve after pulling the pressure adjusting lever with the tailstock sleeveadvanced.

LE11137R0500500250003

First slight-depress of pedal.....The sleeve advances while the pedal is depressed.

Second full-depress of pedal.....When depressed fully, the sleeve advances up to the stroke end.

When depressed, the sleeve retracts up to the stroke end.


Switching between Center work and Chuck workDetermine whether the tailstock is used or not (center work or chuck work) by setting the relevantparameter on the operation panel.

CAUTION

Center-work : The tailstock sleeve operation (advance/retract) is controlled by the foot pedal switch.The spindle can rotate only when the left foot pedal switch is fully depressed.

Chuck-work : The tailstock sleeve operation (advance/retract) is not controllable.The spindle can rotate only when the tailstock sleeve is located at the retract end.

The chuck valve is provided in the line for tailstock sleeve operation to prevent immediatepressure drop when the hydraulic power unit pump stops during the cycle.However, if the workpiece between the centers is left for a long time with the pumpstopped, the pressure will gradually drop constituting hazard. Therefore, be sure to sup-port the workpiece on the machine with a proper block or remove it from the machinewhen it is necessary to stop the hydraulic power unit pump for a long time.


2-6. Interlock

CAUTIONThis machine is equipped with the following interlock functions as standard specifica-tions. These functions are important for safe operation of the machine. Thoroughly under-stand the explanations below before operating the machine.

• Maximum spindle speed interlock functionThe spindle speed is limited by the max. spindle speed (set by G50 command) and theallowable chuck rotation speed. The spindle speed is limited to whichever is lower.Without setting of the max. spindle speed, the spindle cannot be rotated by the pro-gram. For details regarding speed setting method and set values, refer to the OSPOperation Manual separately issued.

• Door interlock E functionSpindle or turret rotation with the door open is very dangerous. This function restrictsthe machine operations when the door is open.a) Max. spindle speed: 50 min-1

Installing Chuck

• Accuracy of adaptor installation section has direct influence to the workpiece chucking accu-racy. Therefore, machine the adaptor very carefully. Required accuracy is within 0.005 mm(0.00020 in.) for run-out on circumference, face run-out, and flatness.

• Any damages such as score or foreign matter on fitting parts and installation surfaces will dete-riorate chuck installation accuracy. Install the chuck only after cleaning both the chuck and theadaptor.After the installation of the chuck, measure run-out of the chuck body circumference and face.Run-out must be within 0.020 mm (0.00079 in.).

• Insert the chuck onto the spindle with the chuck drive pin hole aligned with the spindle pin.Tighten the chuck clamping bolts gradually and uniformly. After the installation, the chuck fits onthe spindle end face in the following manner as illustrated below.

LE11137R0500500300001

• To clamp a workpiece, use only the handle supplied with the chuck. If a workpiece is clampedforcibly by inserting a pipe into the handle hole, chucked part will be distorted causing shorterlife and deteriorated accuracy.If higher clamping force is required for your turning operation, use a larger chuck.

• Never tap a workpiece held in the chuck.

• Select the chuck size meeting the intended machining operation.

CAUTION1) If an excessively long workpiece is held by chucking on one side, the workpiece may

sway and damage the machine internal parts.2) To hold a long workpiece, avoid one-side chucking and use a tailstock or work rests to

securely support the workpiece free end.3) The allowable work length varies with the cutting conditions or workpiece rigidity. As a

criterion, if the length “L” in the figure below is longer than the value calculated by theformula below, use a tailstock.L = L1 + (L1 X 3.5)

4993-E P-54SECTION 4 INSPECTION/MAINTENANCE (FOR TROUBLE-FREE OPERATION)

SECTION 4 INSPECTION/MAINTENANCE (FOR TROU-BLE-FREE OPERATION)

Your CNC lathe is a highly efficient production machine calling for a much higher utilization rate than anengine lathe.This section deals with the maintenance requirements which must be met by every user in order to insureexcellent, trouble-free performance and prolonged life.It also outlines some basic steps to pinpoint possible causes of trouble, together with troubleshooting hints, ifyour CNC lathe is found out of order in any way, or in need of readjustment or repair.Generally, NC lathes are used at three to four times higher “utilization” rates than manually controlled enginelathes. To insure a maximum productive time with a minimum of downtime, the machine must be periodicallyinspected and carefully serviced.A periodical inspection schedule is presented below.

(1) Daily

• Check the oil level gauges (for hydraulic unit, slideway lubricating oil tank, headstock lubricating oiltank), and oil level and flow seen through the sight glass (on the headstock).

• Check the turret and chuck pressures with the gauges on the hydraulic unit (air pressure for the airchuck).

• Apply grease to chuck (air chuck) jaws.

(2) MonthlyThese three items must be carried out after the first month of operation following initial installation of themachine.

• Check the bedways for level and straightness.

• Flush out the hydraulic power unit and change the hydraulic fluid.

(3) Every three weeksThis item must be carried out after the three months of operation following initial installation of themachine.

• Change the oil in the headstock.

• Clean the pulse handle.

(4) Every six months

• Change the headstock lubricating oil.

• Change hydraulic oil in the hydraulic power unit.

In addition to the regular maintenance items given above, there are some maintenance items which should bechecked according to the actual condition of the machine, as described in this section.


1. Lubrication[Supplement]

(1) Always Use the Specified Lubricating Oil.

• If the oil other than specified is used, the lubrication unit might fail to operate normally.

• Lubricating oil used in common with coolant or lubricating oil used in common with hydrau-lic oil might cause corrosion of lubrication unit or mixing of oils to result in lubrication failure,which, in turn, leads to damages on the slideway surfaces.

(2) For Coolant, Use the Specified Coolant.

• Coolant usually contains chemical additives such as activator. If improper coolant is used,lubricating oil will be affected by chemicals and therefore, use the specified coolant so faras possible.

• If coolant which is not our recommendation is to be used, check to be sure that it will notcause any following problems.Mixing with lubricating oil, possible parting, peel of paint, rusting, and swelling of packingsIf a problem is found during the use of the coolant, avoid the use of such coolant.

(3) Amount of Lubricating Oil and Its Discharge Condition Must Be Checked Everyday.

• Whether or not lubricating oil is properly supplied can be checked by checking oil level inthe tank. For normal oil consumption amount, refer to “Slideway Lubrication System”. inthis section.

• Prior to shipment of the machine from our plant, the oil and the coolant tanks are flushedout and must therefore be refilled during the initial installation of the machine.

The machine should be completely and correctly lubricated in strict adherence to thedirections in the Lubrication Chart in the following page.

Note• The above table is based on the JIS B6016-1 standard.

Since we do not have any experience in using the oils other than those indicated bellow,selection should thus be made from them. Because slideway lubricating oil containsadditives such as extreme-pressure additive, it could incur variety of troubles if reactingwith other oils or coolant. Therefore, pay special attention to the use of slideway lubri-cating oil.

• As for service point or amount of lubricating oil of the machine, refer to the InstructionManual of respective machine models.

• Lubricating oil used in common with coolant or lubricating oil used in common withhydraulic oil might cause corrosion of lubrication unit or turbidness of oils to result inlubrication failure, which, in turn, leads to damages on the slideway surface or ballscrew. (We take no responsibility for the troubles caused by using the lubricating oilwhich is not our recommendation.)

• As for oil replenishment for the optional accessories such as special chucks or chipconveyor, refer to the Special Instruction Manual supplied with individual accessories.

• When slideway lubricating oil mixed with coolant and some trouble appears, contactyour local Okuma representatives. They have optional accessories such as oil skimmer.


1-1. Headstock Lubrication System

LE11137R0500600030001

A pressure switch is used to check if the lubrication in the headstock is done properly. Power supply to the control circuit cannot be turned on if the pressure in the lubrication line is belowthe specified level.The pressure is set at 0.2 MPa.

Be sure to use lubricant of this grade.When the machine is operated at a high “utilization” rate, special care should be exercised as tocleanliness and the condition of the oil used. If the oil is dirty, oil changes must be made more fre-quently than specified in the above table.Clean the filter each time an oil change is made.

4. Adjustment of Turret Index Speed

CAUTION

V12 TurretFollow the steps below:

Procedure :

1- Remove the cover

2- Remove the lock nut of the turret index speed adjusting screw.

3- Turn the turret index speed adjusting screw so that the turret index speed will be about 12seconds/rotation.

4- After the adjustment, be sure to secure the lock nut tight.

5- Mount the cover.

V8 Turret (Two-Turret Model)

Adjust the turret index speed to about 8 seconds/rotation.

Explained in this section is the procedure to change/adjust the turret index speed forrespective types of the turret, V12 and V8. However, if the adjustment is made improperly,a trouble will result in the turret index driving system. Therefore, carefully adjust the turretindex speed.

CW turning - index speed decreasesCCW turning - index speed increases

Follow the same procedure as adjusting V12 turret.


Fully open the flow control valve for adjusting the turret index speed while the turret is at a still. Thisis to flow away foreign matter if the valve is clogged. After that close the valve completely. NEVEROPEN THE FLOW CONTROL VALVE WHILE THE TURRET IS ROTATING: IF OPENED, THETURRET WILL ROTATE AT A HIGH SPEED CONSTITUTING HAZARDS TO BOTH THE OPERA-TOR AND THE MACHINE.Turn the adjusting screw counterclockwise gradually with keeping the TOOL INDEX button on theoperation panel pressed, until the specified turret index speed is obtained.After the adjustment, secure the lock nuts and fix the cover as before.

5. Check the Bed LevelThe straightness or level of the bedways will affect the machining accuracy. In case parts cannot beturned to specified tolerances, first check and secure the machine level, then proceed with neces-sary adjustments.

How to remove cover and locate flow control valve Turret index time
