Technical Data
Coating Series with Excellent Characteristics
High-speed dry machining of aluminum alloyhas been realized by adoption of cementedcarbide alloy and coating of DLC (Diamond-Like Carbon) -- an amorphous substancehaving diamond-like properties characterizedby a high degree of hardness, a low frictioncoefficient and wear resistance.It has a low friction coefficient and resistanceto deposition of aluminum alloy. Depositionis reduced even in high-speed dry machin-ing, and excellent properties of machiningsurfaces are provided.
DLC Coating
As a cutting tool coating technique, this coat-ing technique provides improved wear resist-ance and ensures protection of the basematerials (through the use of a compositemulti-layer configuration), centering on thegeneral-purpose TIN G-series. We haveestablished the manufacturing conditions ofvarious series of our company, including theSG series of high-speed steel.
Composite multi-layer coating
We are the first in the world to succeed incommercial use of a diamond film (so-calleda tool of dream), using our coating tech-nique.Diamond coating by vapor phase syntheticmethod provides the close adhesion that hasbeen inconceivable so far. The techniqueensures drastic improvement of cuttingperform-ance in the field of machining the nonferrousmetal, graphite, composite material or alu-minum alloy.
Diamond coating
Our R & D efforts cover the development ofcoating equipment indispensable to thedeveloping of new coating technology.

1) Pilot Hole is required. It is recommended to use same diameter or up to 0.1mm larger than diamter of the long drill. The depth of cut of the pilot hole is 1 to 2 times diameter of the drill diameter.2) Use pecking in hard to cut materials like Stainless Steel & hardened Steels. 3) Recommended feeds and speeds are starting points only. Actual performance will be determined by specific material, the condition of equipment being used and coolant.

TECHNICAL REFERENCE / DRILLSDRILLS
1. PROPER SELECTION OF DRILLSDepending on work material and cutting conditions, standarddrills can be used for drilling holes in materials. However, toensure efficient and economical production, it is important thatthe proper drill is selected for each drilling operation.
3. CORRECT HOLDING OF DRILLS Of the time spent in drilling operations, net cutting time is sur-prisingly short and setting up time is much longer.Consequently, improved efficiency in attaching and detachingof drill from its holder is decidedly important from the point ofview of increased productivity.
5. PROPER CUTTING SPEED AND FEED RATEIncorrect cutting speed and feed may cause the drill to wearexcessively or even to break and will greatly shorten drill life.Cutting conditions are determined by the shape and machiningqualities of the material, condition of the drilling machine, jigsand so forth, select proper values, referring to the cuttingconditions. When deep hole drilling, reduce the cutting speedand feed in accordance with table shown in below.
2.MAINTENANCE OF DRILLING MACHINE,JIGS AND FIXTURES
For prolonging the drill life and maintaining accurate holeproduction, both the drilling machine used and jigs and fixtures must preserve high rigidity.
4.CORRECT CLAMPING OF WORKPIECE
6. REGRINDINGWhen a drill is used until it is completely worn and does notcut, disadvantages will accumulate such as decreased produc-tion, deterioration of surface finish, reduced accuracy, drillbreakage, increased amount of stock removal in regrindingand so forth. It is much better to sharpen a drill before it isworn completely. When correcting regrinding, the followingfive points should be carefully observed:
a) Completely remove the worn part (rough grind).b) Center the chisel point.c) The lengths of each cutting edge must be equal.d) Regardless of the point angle, each cutting edge must be
equally inclined to the axis of the drill.
e) Make the clearance angles proper and each clearance angle identical.

THE MAIN GEOMETRY FACTOR OF DRILLS AND THEIR WORK
When the helix angle isgetting bigger, the cuttingresistance is decreased,but the drill’s rigidity down.High helix angle is adopt-ed for soft material, andlow helix angle is adopt-ed, for brittle material.

FACTORS OF DRILLS
To increase the drill webthickness, the rigidity ofdrill should be bigger. Butthrust is also increasedbecause of long chiseledge. To decease thrust,the thinning is treated.
When the point angle isgetting small, thrust is alsosmall, but torque the getsbigger. For general pur-pose, 118 point angle isadopted. For hard materi-al, or for high-speed cut-ting, 135 is recommended.
If large clearance angle istaken, thrust is decreased,and flank wear is alsodecreased, but cuttingedge is getting brittle. Forhard material, smallclearance angle is taken,for soft material, largeclearance angle is taken.

Shape of lip reliefThe conical grinding method is broadly adopted as the most normal one. The other lip relieves arechosen according to the application when it is preferable to make the highly accurate holes.
Web ThinningThe proportion of drill resistance caused by the various drilling force concentrates on the chisel edge.The thrust force on chisel edge is in the same proportions as that on the lip. Drill-thrust force is verysensitive to variations of chisel-edge length or web thickness. Web thinning reduces drilling thrust andproduces other advantages such as reduced cutting temperature, increased drill life and improved holegeometry. In order to recondition the drill properly, it is necessary to reduce this web thickness.

Chip BreakerSince continuous chips do not discharge easily, it is necessary to break these forcibly. Particularly,to change the shape of continuous chips generated in the deep hole processing of tough materials,it is desirable that the drill shall be provided with a chipbreraker. Examples of chipbreakers areshown below.
ex. Characteristics of the drills for deep hole
To drill a very deep hole, it is necessary for the drills to have thefollowing four features:
1. Good removal of the cutting chip2. Good penetration of the cutting coolant3. Good heat resistance4. High rigidity
We show the geometries for the drills as shown in the illustration.
The drill has a thick web for strength and proper thinning for lessthrust force.

TECHNICAL REFERENCEEND MILLS
1. Correct Selection of End MillsIt is necessary to choose the most suitable end millsconsidering cutting efficiency, accuracy and so on forhigh efficient machining.
Tool MaterialHSS-Co(equivalent to SKH59) shows excellent perform-ance for cutting normal steel to non-ferrous alloy andcast iron. Select coated HSS, PM-HSS, FAX or Carbide formore efficient and long lasting milling.
Number of FlutesGenerally, 2-Flute is used for slot milling because of itswide chip pocket. 4-Flute is used for side milling becauseof its high rigidity.
Helix AngleGenerally 30° is used because better surface finish isobtained by helix angle around 30°. Lower helix is goodfor keyway slotting because the slot inclination is small.The bigger is the helix, the better will be the surfacefinish so that the high helix end mills will be used forcontour milling.

Surface Finish Tool Life Application
1. Nachi Heavy is designed with specially formed and disposed nicks so that it may decrease cutting resistance and minimize waviness or vibrations on the surface finish.
2. Diameter rotation generates a straight line. Therefore surface finish is excellent.3. Chips flow out easily because of their chopped form.4. Cutting fluid penetration is very smooth.
Example of Heavy and other end mills performances
The best endmill selection is as short as possible

1. Nachi Viper Taflet Taps are specially engineered for steels, andrequire less torque than conventional coldform taps. This reducesthe chance of breakage.
2. Nachi Viper Taflet Taps are steam oxide surface treated to limitadhesion from fusion, and carries coolant to the work area. Brightfinish is available when required.
3. Nachi Viper Taflet Taps have more radial sections for higheraccuracy of internal threads in steel. This compares favorably tocoldform internal threads, which aren't always clean and accurate.

TECHNICAL INFORMATION / VIPER T SERIES TAPSTAPS
• Viper T Series are suitable for various material.• "Viper T for STAINLESS" series are the best taps for STAINLESS
STEEL.
Nachi TDT Viper T-Series Taps were specificallydesigned to overcome the major difficulties of spiralfluted taps: oversizing and chip control. An all-newapproach to these limitations also provides double-action tapping — cutting with chamfered teeth, pluscold rolled forming with a specially engineeredshape of thread that we call Taflet Relief.
The results provide two-fold benefits. The first isminimal or no oversized thread diameter over theentire thread length, with smooth thread surfaces.The second is smooth chip ejection, ensuring free-dom from chips for trouble-free performance,especially on machining centers and on unattendedmachining lines.

VIPERViper taps go straight to the heart of tough work with problem-freetapping of stainless steel and other advanced metals. They providesuperior threads and less torque, faster chip removal and coolertapping job after job.
All this because Viper taps are made exclusively of specialty highspeed steels, heat treated to maximize the advanced heatresistance characteristics of Cobalt and Tungsten and the wearresistance of Vanadium.
No tap is better engineered than Viper to demonstrate a longer toollife working in advanced materials with less down time and moreeconomy. The special geometry extends tap life and the standardsteam oxide maximizes the cooling effect to make rigoroustapping easy. Bright finish taps are also available where requiredfor non-ferrous materials or special coatings as required. CNCmanufacturing assures consistent quality time after time.

VIPER TAFLET TAPS (THREAD FORMING)TAPS
Taflet Taps for economical and efficient thread forming
NACHI Viper Taflet taps are designed for economical and efficient tapping of steel. No chips are produced with
Taflet taps. The threads are formed by displacement of the metal. Threads produced this way are generally more
accurate and stronger than threads produced by conventional tapping.
Advantages of NACHI Viper Taflet Taps
Conventional coldform taps for steel require high torque. NACHI Viper Taflet taps have been specially engi-
neered for steels and require less torque, reducing the chance of breaking.
In conventional coldform threading, rapid wear and adhesion due to high frictional heat may occur. NACHI Viper
Taflet tap’s steam oxide surface treatment limits adhesion from fusion and carries coolant to the work area.
Bright finish is also available when required.
Conventional coldform internal threads aren’t always clean and accurate. NACHI Viper Taflet taps have more
radial sections for higher accuracy of internal threads in steel.

The material being tapped is the primary factor in determining the most effective TAPPING SPEED. However thereare a number of other factors which may require consideration. Among these are: thread pitch, thread length, percentof thread, lubrication, tap flute style and chamfer, equipment and method of tapping. The best speed is determinedby experiment on the iob. The table below lists speeds which have proven satisfactory under average conditions.

PRE-TAPPING DRILLING SIZES
Drilling size is strictly concerned Percent of Thread. The following picture shows the relations betweenthe height of the female thread and its sectional area. Here, it's very important to choose the minimizedPercent of Thread as possible the thread needs. Because too much Percent of Thread brings increasedcutting torque which causes excess wear and breakage of the taps.
Percent of Thread = Basic thread OD. x Pre-Tapping Diameter x 100%2 x (Basic Height of Thread)
• Pre-tapping diameter for Cutting Taps
Pre-tapping Diameter = Basic thread OD. – .01299 x Percent of ThreadNo. of threads per inch
• Pre-tapping Diameter for Roll Forming Taps
Pre-tapping Diameter = Basic thread OD. – .0068 x Percent of ThreadNo. of threads per inch

TECHNICAL REFERENCETAPS
THE MANY ADVANTAGES OF NACHI TDT VIPER T-SERIES TAPSThese tops are made of high vanadium E grade high speed steel (HSSEV), which is primarily used forheavy duty taps. The taps are heat treated, followed by a special steam oxide treatment that preventsadhesion. This results in the ability to obtain suitable internal threads from the start, which also extendstap life to more than double that of other taps!
The Specific Advantages
1. Less OversizingTaflet Relief reforms cut threads and controls the thrust of the tap completely. Even if tapped material ismild steel, cutting stops within one thread! High precision uniformity of the tapped limit is obtainablewith little oversizing, regardless of the rigidity of the tapping mechanism. Even when slight oversizingoccurs, the chip-bite between taps and internal threads gets hard so tap breakage and/or torn threadsare reduced.
2. Ideal Flute ShapeAll cutting edges on the chamfered portion are at exactly the same angle, so the chip shape is consis-tent. Smaller than conventional curvature on the bottom flute stretching from the cutting face results insmall curled chips. In addition, Nachi Viper T-Series Taps release chips smoothly, thanks to their spe-cially designed helix angle.
3. Shorter Thread LengthShorter than conventional thread lengths prevent chips from clogging the flutes; reduce bite, twine-round and breakage of the cutting edge. Flute length also provides for excellent chip ejection.
4. GT System For Thread LimitInstead of the usual GH limits, GT limits are applied to Nachi Viper T-Series Taps. Each top has just oneGT number instead of several GH numbers, eliminating troublesome limit selection (see ComparisonChart, below, for details).

The depth of regrind can be 2—3 times the thread height; it is not necessary to regrind full depth of theflute. However, it must be as smooth as possible from the ground rake face position to the root radius.
2. Setting the rake angle
To grind the rake face is to remove wear and the damaged portion.
It is very important to set the rake angle very carefully, otherwise it brings unstable accuracy of female thread,bad surface roughness, short tool life and chipping. The following picture indicates two types of resharpen-ing, which are Grinding Hook Angle by Formed wheel and Grinding Rake Angle by Disk Type wheel.
A. Flute Grinding Way1. The following table shows the common grinding condition for resharpening the taps.
When to Resharpen Taps1. When the taps get or appear to be damaged.2. When the dimensions of the tapped threads begin to get out of tolerance.3. When the surface roughness on threads decreases.4. When the cutting torque starts to increase.5. When the taps start to make a squealing noise.6. When the shape of the tapping chips begin to change.

B. Chamfer Grinding Way
The Chamfer Grinding is carried out by some chamfer grinding machines with being held by collet orbetween centers. Chamfer length and angle are specified as follows:
hand taps (Taper) 8~9 threads ≈4˚~5˚hand taps (Plug) 5 threads ≈7.5˚
hand taps (Bottoming) 1.5 threads ≈24˚taper pipe taps 2.5 threads ≈15˚
parallel pipe taps 4 threads ≈11˚spiral fluted taps 2.5 threads ≈15˚
spiral pointed taps 4 threads ≈9.5˚
Kind of Taps Chamfer Length Chamfer Angle
Resharpening of taper
Relief Angle (α) is calculated as next.α = tan-1 (P x tan λ / πδ)=α0
α : relief angle on taperP : pitchλ : taper angled : basic minor diameterα0 : effective minimum relief angle
α0 is decided as table
