One, the method that whorl milling uses numerical control machine tool to machine whorl as a kind, be in Europe above all, beautiful popularity leaves come. As the development of machine tool of Chinese numerical control, the acceptance that also gets Chinese broad client stage by stage and love. Interpolation of the function of 3 axes linkage that whorl milling is machine tool of center of CNC Machining of have the aid of and G02 or G03 helix dictates, milling of the whorl that finish works. 2, the advantage that method of whorl milling treatment has. 1, because at present the production material of whorl milling cutter is hard alloy, treatment linear velocity can amount to 80 ～ 200m/min, and the treatment linear velocity of high-speed steel tap is 10 ～ 30m/min only, reason whorl milling cutter suits high speed cutting, the surface that machines whorl is bright and clean degree also rise considerably. Tall hardness material and material of high temperature alloy, the thread machining of the alloy that be like titanium, nickel radical alloy is a more difficult question all the time, because high-speed steel tap machines afore-mentioned material whorl,basically be when, cutting tool life is briefer, and using milling cutter of hard alloy whorl is the solution with better effect to hard data thread machining. Can machine hardness to be HRC58 ～ 62. To the thread machining of material of high temperature alloy, whorl milling cutter shows very exceedingly good processability to be able to be mixed likewise super- anticipated macrobian lot. To the whorl aperture of same pitch, different diameter, use tap to machine need to finish cutting tool ability more, but if use treatment of whorl milling cutter, use a cutting tool can. In caustic of filar taper thread grinding, treatment whorl dimension is less than tolerancepublic errand hind to cannot continue to use, can discard as useless only; And wear away when whorl milling cutter, when size of treatment whorl hole is less than tolerancepublic errand, after can undertaking compensation of necessary cutting tool radius adjust through numerical control system, can continue to machine the whorl that gives dimension qualification. 2, same, to score the whorl hole of high accuracy, use whorl milling cutter to adjust the method of cutting tool radius, should get easily than producing high accuracy tap much. To small diameter thread machining, especially in the thread machining of tall hardness material and high temperature material, tap can break off sometimes, jam whorl aperture, make the spare parts discards as useless even; Use whorl milling cutter, because cutting tool diameter compares the Kong Xiao of treatment, although break off to also won't jam whorl aperture, take out very easily, won't bring about a spare parts to discard as useless; 3, use whorl milling, compare with tap photograph, force of cutting tool cutting is reduced considerably, when thread machining of this pairs of big diameters, particularly important, settled machine tool negative charge too big, cannot the problem that drive tap machines normally. Milling cutter of whorl of type of machine clip razor blade already came out 10 years ago, people also realises, the whorl aperture of M20 above is machined on machining center, use whorl milling cutter and use tap photograph to compare, can reduce finished cost considerably. 4, in last few years, the design of milling cutter of whorl of integral hard alloy and manufacturing technology mature stage by stage, development gave the series product with size all ready scope. We from VARGUS of Israel of supplier of solution of thread tool of world-renowned hard alloy (Wagesi) the product of series of whorl milling cutter that the company develops in recent years develops a tendency with respect to what can see whorl milling cutter, the set of Millipro of milling cutter of whorl of hard alloy whole that its develop covered M1. 6 × 0.
35 to M4; Helicool series covered M5 ～ M19; MITM much razor blade, efficient series of milling cutter of machine clip whorl covered range of dimension of M19 ～ M60; Milling cutter of whorl of type of installation of Shellmill set much a tooth-like part of anything, Pan Xi covered M60 ～ M300 the big diameter thread machining of larger even size. Use solution of whorl milling cutter to help an user, make its application more easy, convenient, the company still developed Wagesi TMGen software system, medium already culture, can help an user choose the program of whorl milling CNC with knife and automatic corresponding work out automatically. To application of small diameter thread machining, some aviation industry needs to be in an aluminium on machine 50 M1.

Aperture of 35 whorl blind, the problem that the client encounters is: Because be blind aperture, discharge bits difficulty, use tap to add man-hour to break off easily; Because tap is last working procedure, if the spare parts discards as useless, a large number of handling time that spend on this spare parts will be full loss. Finally, the client chooses treatment M1.

The whorl milling cutter of 35 whorl, linear velocity Vc=25m/min, rotate speed S=4900r/min (machine tool limit) , every turn feed Fz=0.
05mm/r, actual handling time is 4 seconds / whorl, finished namely with a cutting tool all 50 workpiece. 5, some cutter hub produces a business, because cutter hub hardness is HRC44 commonly, to the aperture of small diameter whorl of impaction razor blade, use treatment of high-speed steel tap to compare difficulty, cutting tool life is briefer, break off easily, to M4 × 0.
The thread machining of 7, the client chooses milling cutter of whorl of integral hard alloy, vc=60m/min, fz=0.
03mm/r, handling time 11 seconds / whorl, cutting tool life amounts to 832 whorl, whorl is bright and clean degree first-rate. 6, to thread machining of medium diameter dimension, the aluminium that some enterprise should machine makes a spare parts go up, have M12 × 0.
5, M6 × 0.
5, M7 × 0.
The whorl aperture of 3 5 different measurement, same pitch, need uses ability of 3 kinds of tap to complete treatment previously. Convert now whorl milling cutter, cutting condition: Vc=100m/min, s=8000r/min, fz=0.
04mm/r, the time that machines a whorl is 4 seconds, 3 seconds, 3 seconds respectively, a cutting tool can machine 9000 whorl, finish whole batch after the spare parts is machined, cutting tool has not damaged. 7, in large generate electricity, metallurgy equipment processes a trade, pump, a powerful person processes a trade, whorl milling cutter solved the treatment problem of big diameter whorl, the ideal that makes efficient, low cost machines cutting tool. Like some a powerful person kind the spare parts processes a business, need machines 2" × 11BSP-30 whorl, material is cast steel, hope to improve treatment efficiency. Place type whorl milling cutter through choosing engine of many bits chamfer, much razor blade, use ＝ of Vc=80m/min, S=850r/min, Fz 0.
The cutting parameter of 07mm/r, realized whorl of handling time 2min/ , bit life 620, improved the treatment efficiency of big diameter whorl effectively. 8, whorl milling cutter is provided as a kind of advanced knife that develops quickly in recent years, more and more be accepted by company place widely, show outstanding treatment performance, become an enterprise to reduce thread machining cost, raise the efficiency, powerful weapon that solves thread machining difficult problem.
