In recent years, the Gao Jin that prop up gives treatment (the technology that HFM) place asks is being developed by apace all the time. Use this kind of technology, machine tool jockey apace purify cuts bits in great quantities and can improve productivity considerably accordingly. The advantage of HFM milling cutter depends on the special geometry angle of milling cutter itself and razor blade. Tool cutting edge angle and cutting deepness are small, for counterbalance the ply that break bits reachs an acceptability numerical value, every tine feed must very tall. See computation break the formula of bits ply on average please, this concept can become clear rise: Run medium productivity: Gao Jin allows faster metallic excision to lead to treatment. Hm=fz · (· of Ae)½ · SinKDcfz=hm (in type of Dc)½ · 1aesinK: Hm -- break bits ply Fz on average -- every tine feed Ae -- cutting width / Dc of radial cutting deepness -- K of cutting tool diameter -- the K part of razor blade of tall feed of tool cutting edge angle is quite small (13, 8 ° ) ; That is to obtain acceptability break bits ply on average, fz is worth must very tall reason. Chart (among lower part) express feed (Y axis) with tool cutting edge angle (X axis) the function that form concerns, when cutting of cutting tool full blade (when Dc/ae=1) , its break bits ply on average for 0. 1 Mm. The another advantage of the cutting tool of this kind of type and cutting deepness is axial of stress distributinging edge direct front main shaft, make sure the flexibility that stability prevents to be caused by transverse stress is out of shape. Accordingly, they are reliable cutting tool, apply to especially grow the cutting that hangs extended rough machining and difficult treatment material, be like high temperature alloy and stainless steel.
