Collision prevention
�World’s first “Collision-Free Machine”CAS prevents collisions in automatic or manual mode, providing risk-free protection for the machine and great confidence for the operator.
�Chatter-free applications for maximum performanceChatter is suppressed by navigating to the best amplitude and wave cycle—without decreasing spindle speed. This helps customers to boost productivity.
What you want to see and do, conveniently come together in a “single-mode operation.”First, select one of three operation screens.Then simply touch the screen or press a function key to see and do your job.

Automation can be achieved easily with a simple mechanism in which the bucket swings and discharges workpieces outside the machine.
Up to 10 pairs of tailstock positions can be set, enabling continuous machining of workpieces with 10 different lengths without setup. In addition, thrust can be switched between high and low without resetting the workpiece. (Tailstock thrust high/low switch: option) High accuracy positioning is also possible with a high speed linear guide employing a ball screw guide.
A variety of milling operations can be accommodated with high-accuracy, wide-range Y-axis travel using a double slide system. Achieves complete multitasking with a single chucking (MY specifications).
With these sub-spindle specifications, front and back machining can be done on a single LB2000 EX .Interference is not a worry even in back face machining with a multitasking V12 radial turret(W, MW specifications).

Energy-savings from PREX motorPREX motor developed by Okuma eliminates rotor winding and achieves small size and efficiency.High output, low heat generation spindle drive system is used.
�Energy efficiency 5% increase �Energy efficiency 10% decrease
In environments with normal temperature changes, machining accuracies equivalent to those in
temperature-controlled rooms are achieved.
As long as the operator is comfortable, there is no need for air conditioning to ensure accuracy.

Reduce machining chatter Good threads from the first pieceFeed axis perfectly synchronized with changing spindle speeds.Thread pitch accuracy is maintained even if the spindle speedchanges during threading. Cutting conditions without chatter canbe found by using spindle override during threading.As a result, you get good quality threads from the first piece.
Holds down machining chatter as spindle speed is periodicallychanged and resonance points change, when cutting large,thin workpieces or small-diameter, long workpieces.
Cutting is divided into multiple cuts by simply designating depth ofcut, amount of relief, and amount of withdrawal, and tool damagefrom chip clogging is prevented. In addition, if overload is detectedduring synchronized tapping, machine returns to machining startpoint with synchronized feed and stops with alarm.
Returns to machining start point when totaldepth of cut reaches amount of withdrawal.

Optional Specifications
A simple function key operation is all it takes to shift a zero offset to either the left or right end of a workpiece. The required zero offset will be calculated automatically based on jaw and workpiece lengths. (when the tool offset is set with reference to the turret tool mounting surface)
Templates like this make it easy to set required jaw shape, tool, and cutting conditions.
Part programming not required to do this.
Easy Operation
OSP-P300L Okuma Sampling Path Control
Operation screen split into four displays
Forming soft jaws Zero offsets
Simultaneous display includes setup work, current position needed in confirming movement in trial machining, NC program, and graphic simulation.
Tool registration
Register data for all of your tools. Since the registered tool data is also used by Okuma auto programming (Advanced One-Touch IGF) and a collision check function (Collision Avoidance System), this screen will complete the entire registering process.
When loading a tool in the machine, simply select it from among the registered tools.ATC manual operation does not require inputting the tool number. Just select the tool from the list and press the function key.

To protect your factory and equipment from fire and assure continued safe operation, observe the following fire safety precautions whenever you operate machinery. Whenever possible, avoid the use of oil-based coolants for cutting operations. Sparks caused by hot chips, tool friction, and grinding can cause fires. Always observe the following safety measures to ensure safe operation when machining flammable materials or when performing dry machining.
Before machining any material designated by law as a flammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of fire prevention, and observe the precautions given in (2) above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and water-soluble coolants will react to produce hydrogen gas, resulting in an explosive fire if any chip should ignite.
Dry machining is a fire hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any flammable objects near the machine and do not allow chips to over accumulate. In addition, be sure to check cutting tools to make sure of their service life and the condition of the tool edge, and observe the precautions regarding oil-based coolants given in (2) above.
(1) Use nonflammable cutting fluid coolant. (2) When the use of an oil-based coolant is unavoidable:
Before you begin machining, check cutting tools to make sure of their service life and the condition of the tool edge, and choose cutting conditions that will not cause a fire. Periodically clean the coolant filter to maintain sufficient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of fire: Place a fire extinguisher near the machine, have an operator constantly monitor operation, and install an automatic fire extinguishing system. Do not place flammable materials near the machine.Do not allow chips to over accumulate. Periodically clean the inside of the machine and the area surrounding it.Check that the machine is operating normally. Never run the machine unattended. Since an automatic fire extinguishing system and other peripherals are needed for grinding operations, please let us know as soon as possible if you plan to perform such operations.
