【正文】 The treating being remended by is suitable to their standard paratively like the parameter , material quality has the certain difference with domestic part , this difference shows paratively obviously , some parameters can apply directly, but some effect dispatches right away paratively 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 pany standard and.The technology selecting and using the domestic cutter , seldom having the bright metal remending high speed to chop parametric , is necessary making an experiment, get the paratively satisfied parameter , produce a manufacturer had better to select and use the fixed cutter , cut down the number of tim。4current cutter enterprise has already done many jobs in the field of the technology resolving the quickcutting cutter , serving facing the cutter processing may help to solve much problem , the cutter has produced a manufacturer being the main body , the reference cutter has produced the technology parameter that the manufacturer provides.Four, improve quickcutting mould efficiency technology1 cutter diameter and the length choice2 HSM and the EDM choice3 does cutting and the lubricating cooling4 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 rationallyHigh speed bright metal cuts the mass processing part material abroad fairly good, material quality level is identical , the treating function parison is stable。s cuts mould finish machining stiffly.Delcam adopt mm diameter cutter to process the narrow slot , rotation rate 40000 rpm , 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。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 trend1) treating route is nimble , the surface form is plicated。s to have.1 highspeed machine tool technology parameter demandsProcess centre chief axis highpower , high rotation rate , satisfied rude finish machining。5) 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 solvingIn 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。3) 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 processes1) 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 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 mould gradually in abroad has adopt quickcutting already monly , quickcutting has produced a mould already being the general trend that the mould makes gradually , has improved the mould efficacy and mass greatly. Adopt quickcutting to replace electric spark producing a mould , can get on the stick obviously , improves mould accuracy , life time growing.2 high speed processes application in making in the mould quickcutting merit:1) cutter high rotation rate and the machine tool height enter be given to and high acceleration , improve metal excision rate greatly。 The home ap
