Machine efficiency to raise a pattern, reduce production cost, can use 5 rods machining center and processing technique of 5 axes CAM, its advantage is to be able to choose optimal treatment condition, raise intensive of working procedure of treatment precision and treatment quality, implementation to change etc. To achieve this one goal, optimized high accuracy cutting tool and high-powered knife handle (or the knife is placed) it is indispensable element. Below one ゲ of ム of brief introduction ェ ニ of ヶ of ニ of · フ ラ the high speed cutting of company limited new development (HSC) hard alloy establishs knife handle of puissant clamp of milling cutter and PowRgrip. (1) HSC hard alloy establishs hard alloy of milling cutter HSC to establish milling cutter property outstanding, can reduce finished cost significantly, 5 rods can be produced adequately when high speed milling the function of machining center, shorten substantially handling time. HSC hard alloy establishs milling cutter to have the following characteristic: ① is high-powered hard alloy matrix; ② can stabilize the cutting blade that has high speed milling; ③ has the TiAlN coat of tall hear resistance; Cervical diameter is less than ④ cutting tool petiole diameter; Precision of ⑤ knife handle: H5; ⑥ establishs precision of milling cutter external diameter: φ 8mm is the following: 0 ～ - 0.

02mm; φ 8mm above: 0 ～ - 0.

04mm; Precision of ball head radius: ± 0.

01mm; ⑦ but all workpiece material of milling HRC66 and the following hardness; ⑧ φ 16mm establishs milling cutter to have 16 a tooth-like part of anything at most. (2) the treatment property that knife handle of PowRgrip puissant clamp establishs milling cutter to produce HSC hard metal adequately, the tigidity that improves knife handle and precision are very important, this also is one of tasks that realize treatment of high level mould. The knife handle of PowRgrip puissant clamp of new development is system of clamp of cutting tool of a kind of tall tigidity, high accuracy, the bedspring collet that it will have tiny taper with hydraulic pressure means presses knife handle to realize cutting tool clamp, the hot pressing that solved past existence cooperates to hold knife time long, right material of cutting tool petiole has limitation, knife handle the problem such as life weak point, the tigidity that improved knife handle and diameter jump precision. Knife handle of PowRgrip puissant clamp has the following characteristic: ① changes knife time short (10 seconds less than) ; ② repeats service life to grow (20000) ; Torsion of ③ close solid is big (φ 20mm petiole: 380Nm) ; ④ diameter jumps precision is tall (3 μ M is the following) ; ⑤ clip holds function and cutting tool material to have nothing to do character; ⑥ knife mix is outstanding extend adjust precision tall (less than of 10 μ M) ; ⑦ absorbs cutting vibration capability is strong. Machine example: Use φ 16mm establishs steel of carbon of S45C of milling cutter milling, rotate speed 6000r/min, every tine feed 0.

1mm. Cooperate clamping apparatus, hydraulic pressure clamping apparatus and PowRgrip knife handle to using hot pressing respectively already machined exterior surface roughness Ra undertook detecting, the result makes clear, cooperate clamping apparatus photograph to compare with hot pressing, the cutting tool life that uses PowRgrip knife handle rose 180% , conversion is tool charge, can save cost 44% .
