PROPER SELECTION OF DRILLS Depending on work material and cutting conditions, standard drills can be used for drilling holes in materials. However, to ensure efficient and economical production, it is important that the proper drill is selected for each drilling operation.. CORRECT HOLDING OF DRILLS Of the time spent in drilling operations, net cutting time is surprisingly short and setting up time is much longer. Consequently, improved efficiency in attaching and detaching of drill from its holder is decidedly important from the point of view of increased productivity. 5. PROPER CUTTING SPEED AND FEED RATE Incorrect cutting speed and feed may cause the drill to wear excessively or even to break and will greatly shorten drill life. Cutting conditions are determined by the shape and machining qualities of the material, condition of the drilling machine, jigs and so forth, select proper values, referring to the cutting conditions. When deep hole drilling, reduce the cutting speed and feed in accordance with table shown in below. Speed and feed reductions for drilling deep holes HOLE CUTTING SPEED FEED DEPTH REDUCTION RATE REDUCTION RATE Times Diameter 0% 0% Times Diameter 0% 0% 5 Times Diameter 0% 0% -8 Times Diameter 5-0% 0%. MAINTENANCE OF DRILLING MACHINE, JIGS AND FIXTURES For prolonging the drill life and maintaining accurate hole production, both the drilling machine used and jigs and fixtures must preserve high rigidity.. CORRECT CLAMPING OF WORKPIECE. REGRINDING When a drill is used until it is completely worn and does not cut, disadvantages will accumulate such as decreased production, deterioration of surface finish, reduced accuracy, drill breakage, increased amount of stock removal in regrinding and so forth. It is much better to sharpen a drill before it is worn completely. When correcting regrinding, the following five 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.

High helix angle is adopted for soft material, and low helix angle is adopted for brittle material. When the point angle is getting small, thrust is also small, but torque the gets bigger. For general purpose, 8 point angle is adopted. For hard material, or for high-speed cutting, 5 is recommended. Web Thickness To increase the drill web thickness, the rigidity of drill should be bigger. But thrust is also increased because of long chisel edge. To decrease thrust, the thinning is treated. Clearance Angle Back Taper Small Small Small Small Good Big Small Small Small Small Big Big Big Big Small Bad Small Big Good If large clearance angle is taken, thrust is decreased, and flank wear is also decreased, but cutting edge is getting brittle. For hard material, small clearance angle is taken, for soft material, large clearance angle is taken. When back taper is getting bigger, torque is smaller, and worn margin length is also smaller. But too much back taper has less guide performance, and straightness of hole is decreased.

143 TECHNICAL REFERENCE / DRILLS Shape of Lip Relief The conical grinding method is broadly adopted as the most normal one. The other lip reliefs are chosen according to the application when it is preferable to make the highly accurate holes. Shape Features - Effects Application Symbol Conical the most normal grinding method The lip relief angle becomes greater as to it approaches to the center from corner because of grinding the lip relief conically.

The thrust force on the chisel edge is in the same proportion as that on the lip. Drill-thrust force is very sensitive to variations of chisel-edge length or web thickness. Web thinning reduces drilling thrust and produces other advantages such as reduced cutting temperature, increased drill life and improved hole geometry. In order to recondition the drill properly, it is necessary to reduce this web thickness.

231 TECHNICAL REFERENCE. Correct Selection of End Mills It is necessary to choose the most suitable end mills considering cutting efficiency, accuracy and so on for high efficient machining. Tool Material HSS-Co(equivalent to SKH59) shows excellent performance for cutting normal steel to non-ferrous alloy and cast iron. Select coated HSS, PM-HSS, FAX or Carbide for more efficient and long lasting milling. Number of Flutes Generally, -Flute is used for slot milling because of its wide chip pocket. -Flute is used for side milling because of its high rigidity. Helix Angle Generally 0 is used because better surface finish is obtained by helix angle around 0. Lower helix is good for keyway slotting because the slot inclination is small. The bigger is the helix, the better will be the surface finish so that the high helix end mills will be used for contour milling.

243 TECHNICAL INFORMATION / VIPER T SERIES TAPS Features Viper T Series are suitable for various material. "Viper T for STAINLESS" series are the best taps for STAINLESS STEEL. Work Materials Structural Steels, Carbon Steels, Alloy Steels, Stainless Steels, Aluminum Alloys Performance Taflet Relief Nachi TDT Viper T-Series Taps were specifically designed to overcome the major difficulties of spiral fluted taps: oversizing and chip control. An all-new approach to these limitations also provides double-action tapping - cutting with chamfered teeth, plus cold rolled forming with a specially engineered shape of thread that we call Taflet Relief. Chamfered Teeth The results provide two-fold benefits. The first is minimal or no oversized thread diameter over the entire thread length, with smooth thread surfaces. The second is smooth chip ejection, ensuring freedom from chips for trouble-free performance, especially on machining centers and on unattended machining lines.

252 TAPS VIPER Viper taps go straight to the heart of tough work with problem-free tapping of stainless steel and other advanced metals. They provide superior threads and less torque, faster chip removal and cooler tapping job after job. All this because Viper taps are made exclusively of specialty high speed steels, heat treated to maximize the advanced heat resistance characteristics of Cobalt and Tungsten and the wear resistance of Vanadium. No tap is better engineered than Viper to demonstrate a longer tool life working in advanced materials with less down time and more economy. The special geometry extends tap life and the standard steam oxide maximizes the cooling effect to make rigoroustapping easy. Bright finish taps are also available where requiredfor nonferrous materials or special coatings as required. CNC manufacturing assures consistent quality time after time. COMPARISON CHART

259 TAPS VIPER TAFLET TAPS (THREAD FORMING) Taflet Taps for conomical and fficient hread orming 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 engineered 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.

282 TECHNICAL REFERENCE THE MANY ADVANTAGES OF NACHI TDT VIPER T-SERIES TAPS These tops are made of high vanadium E grade high speed steel (HSSEV), which is primarily used for heavy duty taps. The taps are heat treated, followed by a special steam oxide treatment that prevents adhesion. This results in the ability to obtain suitable internal threads from the start, which also extends tap life to more than double that of other taps! The Specific Advantages. Less Oversizing Taflet Relief reforms cut threads and controls the thrust of the tap completely. Even if tapped material is mild steel, cutting stops within one thread! High precision uniformity of the tapped limit is obtainable with little oversizing, regardless of the rigidity of the tapping mechanism. Even when slight oversizing occurs, the chip-bite between taps and internal threads gets hard so tap breakage and/or torn threads are reduced.. Ideal Flute Shape All cutting edges on the chamfered portion are at exactly the same angle, so the chip shape is consistent. Smaller than conventional curvature on the bottom flute stretching from the cutting face results in small curled chips. In addition, Nachi Viper T-Series Taps release chips smoothly, thanks to their specially designed helix angle.. Shorter Thread Shorter 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.. GT System For Thread Limit Instead of the usual GH limits, GT limits are applied to Nachi Viper T-Series Taps. Each top has just one GT number instead of several GH numbers, eliminating troublesome limit selection (see Comparison Chart, below, for details).
