ven to and high acceleration， improve metal excision rate greatly。 2) quickcutting diminutions cut a force。 3)quickcutting heat major part generate heat from the cuttings entrainment，workpiece being short。 4)quickcutting cut down vibration， improve treating mass。 high speed treating apply to the beneficial result that the mould processes 1) fleetness rough process and half finish machining, improve treating efficiency。 2) High speed highaccuracy finish machining replace only entire the height processing， indicating mass， form accuracy rise， 50%, cuts down repair a mill by hand than EDM processes a potentiation。 4) cuts the surface processing final molding stiffly， improve surface mass , form accuracy, the treating (not only being that surface harshness is low, and the surface radiance is high)， being used for plicated surface has more advantage。 5) the surface loss that EDM treating produces， improve mould lifespan 20%。 processes an electrode rapidly bining with the CAD/CAM technology , especially, the form is plicated , thinwall is similar to an electrode. 3 adopt quickcutting to process a mould needing the problem solving In in the homeland, since the aspect cause such as fund， technology， the quickcutting applying produce a mould be in the initial stage stage. Return the machine tool， cutter， handicraft back to existence as well as some problem of aspect needs to proceed orderly other solve. The shorting is that finished cost is high, correct cutter sigmatism have paratively high demand, can not have used big cutters， need to have the plicated puter programming technology to be used for support, equipment running cost height. Two, the high speed processing a mould39。 s processes a machine tool Mould finish machining and hard cutting treating require that the numerical control highspeed machine tool， form board， model put up the precision processing need，higheffect numerical control machine tool mould aiming at produces a lot of machine tool enterprise， some treating centres 60% all above of the machine tool producing a factory sells enterprise to a mould. The fixed assets having 5 billion yuan without exception in the uping several years throws into mould industry， 80% is the machine tool buying a mould process equipment， just saying every year having 4 billion yuan of RMB to buy Jinqie among them. At present average our country numerical control machine tool utilization ratio approximately 20%, the highspeed machine tool utilization ratio 3~5%. Also, mould enterprise has the unit suitable to buy a highspeed machine tool， plies with 6000 ~40000 rmp39。 s to have. 1 highspeed machine tool technology parameter demands Process centre chief axis highpower , high rotation rate， satisfied rude finish machining。 The finish machining mould wants to need to reach 15000 ~20200 rmp like the cutter， the machine tool with minor diameter. Generally, the chief axis rotation rate machine tool under 10000 rpm can carry out rough process and half finish machining，cannot reach the finish machining accuracy。 Have no way to reach 400 the above m/min cutting speed. 2 five scrolls of machine tools application increases a trend 1) treating route is nimble， the surface form is plicated。 2) treating range is big , the various type mould suitable processes。 3) cuts lifespan of condition easy to cut down cutter wear， to raise a cutter,。 3 the softwares buying CAD/CAM and highspeed machine tools assort On the grounds of the machine tool， major part counting， having several billions U. S. dollar to be used to enter port every year, the electromachining machine tool and the highspeed machine tool need to import. Three,quickcutting mould cutter technology Quickcutting processes the cutter needing allocating proper quickcutting. Progressing processing cutter material39。 s in high speed has urged development of high speed treating. The cutter， knife edge headquarter and high tenacity base gathering crystal strengthening the ceramics cutter being able to be used giving consideration to high hardness experience and observe carbide alloy coating being possibility. Gather the crystal cube nitriding boron (PCBN) bit, whose hardness may amount to 3500 ~4500 HV. Gather crystal miamond (PCD) it39。 s hardness but amount to 6000 ~10000 HV. Germany SCS,Japan Mitsubishi (magical steel) and Sumitomo, Switzerland Shanteweike， USA Kenna are in recent years swiftly large wait for the famous abroad cutter pany to successively have debuted the respective quickcutting cutt。
