Switzerland Shanteweike，USA Kenna are in recent years swiftly large wait for the famous abroad cutter company to successively have debuted the respective quick-cutting cutter, not only cutter having average structural steel of quick-cutting, the ceramics cutter still having direct quick-cutting of energy quenching hard steel is waiting for an effect to surpass the hard cutter，especially the coating cutter appears all of a sudden，bringing into play in quenching half finish machining and finish machining of hard steel. New cutter material and cutter technology appearing already make the bottleneck problem that high speed has processed no longer be able to appear on the cutter.
But，expensive entrance cutter price also blocks quick-cutting mould key factor.
Above to come to saying the cutter and the cutter holder acceleration reach 3 gs the sort, the cutter circular runout needs to be smaller than 0.015 mm，but the knife length is unable greater than 4 times cutters diameter. The reality according to SANDVIK company has counted，the carbide alloy has stood on in the entirety using carbon nitriding titanium (TICN) coating when milling cutters (58 HRC) carry out high speed bright metal chopping， rough process cutter linear speed has been 100 m/m in about，whose linear speed has exceeded but 280 m/min when finish machining and microstoning. Such demands to cutter material (include the hardness，tenacity，red hardness keep the form (include row of crumbs function , surface accuracy，dynamic balance sex etc. (cutting the function)， the cutter under high temperature state)) as well as cutter life-span all has very highly.
Experience according to in the homeland mould high speed finish machining, linear speed has exceeded 400~800 m/min when adopt the young diameter ball head milling cutter to carry out mould finish machining. The machine tool choosing sufficient high-speed's cuts mould finish machining stiffly.
Delcam adopt 0.8 mm diameter cutter to process the narrow slot，rotation rate 40000 rpm , 0.1 mm depth，feed speed 30 m/min.
1 chooses the cutter parameter，the cutter waits if shouldering an anterior angle. The cutter requires that the ability processing request shock resistance tenacity more highly，requiring that heat resistance pounds than average is strong;
2 adopts various method improving cutter life-span，reduces cutter cost.
3 adopt the high speed hilt，HSK hilt，heat pressing applying the most being at present to pretend to grip a cutter. Pay attention to a cutter pretend to grip overall in the day afer tomorrow dynamic balance;
4 current cutter enterprise has already done many jobs in the field of the technology resolving the quick-cutting cutter，serving facing the cutter processing may help to solve much problem，the cutter has produced a manufacturer becoming the main body，the reference cutter has produced the technology parameter that the manufacturer provides.
Four, improve quick-cutting mould efficiency technology
1 cutter diameter and the length choice
2 HSM and the EDM choice
3 does cutting and the lubricating cooling
4 feeds choice: Move forward generally giving amounts〈milling cutter diameters 10%，move forward giving a width〈milling cutter diameter 40%. According to material, condition chooses the parameter processing handicraft rationally
High speed bright metal cuts the mass processing part material abroad fairly good, material quality level is
identical , the treating function comparison is stable; But, the cutter that the company produces abroad is also that the standard makes an experiment with their material; The treating being recommended by is suitable to their standard comparatively like the parameter，material quality has the certain difference with domestic part，this difference shows comparatively obviously，some parameters can apply directly，but some effect dispatches right away comparatively during the period of high speed bright metal chops if using their cutter. But select and use part material quality in the homeland like enterprise having the certain standard, what be put into use part material, can use the part material quality that high speed processes especially，the general meeting is limited in some part material range inner, that this applies the high speed processing technology to us has also provided advantageous condition，has been able to apply to less treating material within range. Being needing to emphasize that here, must choose the treating technological parameter optimizing out a set of capital suitable enterprise on these material，is brought into company standard and. 现代模具制造英文文献和翻译(3):http://www.youerw.com/fanyi/lunwen_2521.html
