The characteristic of milling stainless steel is: The adhesiveness of stainless steel and frit are worn the gender is strong, cut bits easy conglutinate is on milling cutter tooth, make cutting condition exasperate; When going against mill, tooth preexistence is already sclerotic apparently glide, increased to machine sclerotic trend; The concussion when milling, vibration is bigger, make blade of easy collapse of milling cutter tooth is mixed wear away. Milling stainless steel establishs milling cutter to be able to make material of milling cutter tooth with hard alloy except upright milling cutter and part outside, of all kinds milling cutter all uses the rest high-speed steel, especially tungsten, molybdenum department and tall vanadium high-speed steel have favorable effect, durability of its cutting tool can raise 1 ～ than W18Cr4V 2 times. The hard alloy brand of milling cutter of the appropriate stainless steel that make has YG8, YW2, 813, 798, YS2T, YS30, YS25. When milling stainless steel, cutting blade wants already sharp want to be able to bear again concussion, the chamfer that hold bit wants big. Can use milling cutter of big helix angle (columnar milling cutter, establish milling cutter) , helix angle B increases 45 ° from 20 ° (N=5 ° ) , cutting tool durability can raise 2 times above, because right now G0e of the horn before the job of milling cutter increases 27 ° above by 11 ° , milling is light. But B value shoulds not be again great, establish milling cutter especially with B ≤ 35 ° are advisable, lest weaken tooth. Use undee blade to establish milling cutter to machine stainless steel to be in charge of material or Bao Bi, cutting is light, vibration is little, cut bits brittle, workpiece is not out of shape. Establish milling of milling cutter high speed with hard alloy, but dislocation carries stainless steel of milling cutter milling to be able to obtain favorable result. When milling stainless steel, answer to use treatment of suitable mill law as far as possible. Law of asymmetry suitable mill can make sure cutting blade makes the same score quietly to be cut from inside the metal from, area of contact of the felt that cut bits is lesser, the action that leaves mental efforts in high speed falls to be swung easily, when lest tooth is cut afresh,entering work, generation of face of the knife before the concussion that cut bits flakes and collapse blade phenomenon, raise the durability of cutting tool. Use spray cooling law effect is most distinct, can raise milling cutter durability one times above; If use general 10% emulsion are cooling, should make sure cutting fluid discharge achieves sufficient refrigeration. When stainless steel of milling of hard alloy milling cutter, take Vc=70 ～ 150 M/min, vf=37. 5 ～ 150 Mm/min, the basis answers to combine gold date and workpiece material in the meantime differ to be adjusted appropriately.
