【正文】 r 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。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。 3) cuts lifespan of condition easy to cut down cutter wear， to raise a cutter,。 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。s to have. 1 highspeed machine tool technology parameter demands Process centre chief axis highpower , high rotation rate， satisfied rude finish machining。 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。 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。 high speed treating apply to the beneficial result that the mould processes 1) fleetness rough process and half finish machining, improve treating efficiency。 3)quickcutting heat major part generate heat from the cuttings entrainment，workpiece being short。 The IT industry year increases % speed equally exceeding 20， the need to the mould accounts for 20 of mould marketplace %.2020 annual Chinese machine tools implements industry output value. will continue to increase. Our country mould fabrication market potential is enormous. The basis data counts， in recent years， our country mould year gross output value reaches 3 billion U. S. dollar， entrance exceeds 1 billion U. S. dollar， exceed 100 million U. S. dollar outlet. Increase by from 25% to increase to 2020 50% of 1995. The expert foretells that abroad: Asia portion being occupied by in mould fabrication in the whole world, will from 25% to increase to 2020 50% of 1995. Chinese mould industry has been expanding by leaps and bounds， has formed east China and two big South China bases, and has expanded gradually arriving at other province. In 2020 (Shandong， Anhui， Sichuan) in 1996， mould manufacturing industry output value annual average growth 14% , grows by 25% in 2020. In 2020 our country mould output value is 45 billion RMB. The gross product place occupies the world the 3rd， exports a mould increases % pared to last year 336,800,000 U. S. dollar. But, contents low our country technology moulds already pile up in excess of requirement， very most support of accurate， plicated top grade mould imports. Every year the entrance mould exceeds 1 billion U. S. dollar. Exceed 100 million U. S. dollar outlet. Precise mould accuracy requires that 3 mu ms， largescale moulds require that 8000 satisfied kN agree well with model force injection machine request in 2 ~； The minitype mould needs the request satisfying the diameter 1 mm silent stock tube. At present, adopt quickcutting to produce a mould already being the general trend that the mould makes, a few moulds have produced a manufacturer in abroad， highspeed machine tool large area has substituted the electric spark machine tool， quickcutting has improved the mould efficacy greatly. Machine tool enterprise aims at mould manufacturing enterprises， some treating centres 60% all above of the machine tool producing a factory sells treating enterprise to a mould. The mould fabrication enterprise substituting the electric spark finish machining mou
