What kind of tool can you use
?cr18ni9ti with silvery white breadcrumbs end milling cutter, the geometric parameters for gf = 5 °, gp = 15 °, 15 °, af = = ap 55 °, 5 °, kr = k 'r = 35 °, 30 °, bg g01 = - = 0.4 mm, re = 6 mm, when Vc = 50 ~ 90 m/min, Vf = 630 ~ 750 mm/min, and a' p = 2 ~ 6 mm per tooth feeding up to 0.4 ~ 0.4 mm, milling force decreases 10% ~ 15%, and the milling power down 44%, also greatly improve the efficiency. Its principle is on the main cutting edge grinding out negative chamfer, milling artificially generated when the devolop tumor, instead of cutting edges for cutting, the devolop tumor of the anterior horn of gb of 20 ~ 302, as a result of the action of the main Angle, the devolop tumor caused by a knife before surface parallel to the thrust of the cutting edge of the chip to become vice flow, to take away the cutting heat, reduces the cutting temperature.
Can use the big spiral Angle cutter (cylindrical milling cutter, end mill), spiral Angle b increased from 20 ° to 45 ° (designed.the gn = 5 °), the tool life can be increased by more than 2 times, because work at the moment of the milling cutter rake Angle g0e by 11 ° increased to more than 27 °, milling fast. But b value should not be again big, especially the vertical milling cutter with b 35 ° or less advisable, so as to avoid weakening the blade. The stainless steel tube or thin wall parts are made of corrugated edge milling cutter, the cutting is light, the vibration is small, the chip is fragile and the workpiece is not deformed. The stainless steel with carbide end milling cutter, indexable milling cutter and milling cutter can achieve good results.
Car milling stainless steel in addition to the vertical milling cutter and carbide end milling cutter and the parts of the cutter material outside, the rest of the all kinds of milling cutter adopt high speed steel, especially high tungsten, molybdenum and vanadium high speed steel has a good effect, the milling processing of stainless steel, cutting edge sharp and should be able to withstand shocks, let crumbs slot
