Fall this synergism -- all along is the major challenge that die manufacturer faces. Came from the influence of the business domain such as 3C, car 2019 especially, make frequency of many die manufacturer outstanding achievement bright red light. "Downstream industry is pounded, upper reaches is made in the various and complex case such as workpiece, machine tool, material " , mould person is very difficult!Traditional pattern however, downstream industry seems to be able to be sent only look at future; Come from the treatment difficult problem with the complex respect such as workpiece, machine tool, material to be able to be solved however at instantly. Choose cutting cutting tool correctly, can help die manufacturer develop the greatest potential of treatment machine tool adequately, improve treatment efficiency greatly. The development it may be said of mould technology and cutting tool technology is to supplement each other, the technology of the mould can stimulate manufacturer of hard alloy tool newlier improve appearance of cutting tool geometry to design ceaselessly, update its cutting tool to make a technology ceaselessly. Current, development went to have the special milling cutter that can process a variety of data already, also have the general milling cutter that suits a variety of treatment.Give typical examples: Agree accept GOmill GP is general-purpose milling cutter is on processing technique, general pattern treatment can use high speed milling. And the promotion that cutting tool hardness can restrict technology of high speed cutting greatly and application, raise cutting tool so service life and reduce cutting tool wear extent, very important to raising a spare parts to machine precision and efficiency. Choose appropriate cutting cutting tool, it is the key that the mould machines.How does treatment of nice spare parts choose outstanding cutting cutting tool? The cutting tool of coating of choice hard alloy of cutting tool material, get together the application that brilliant enhances cutting tool of pottery and porcelain, make the matrix that cutting tool holds the blade department that has tall hardness and tall tenacity concurrently at the same time becomes a possibility, promoted the development that high speed machines. For example: Get together nitrogen of brilliant cubic metre changes boron (PCBN) the hardness of bit can amount to 3500-4500HV, get together brilliant diamond (PCD) hardness can amount to 6000-10000HV.The choice of precision of cutting tool of milling cutter of commonly used pottery and porcelain generally speaking, when requirement cutting tool and the acceleration that the knife places achieve 3g above, the radial of cutting tool is jumpy should be less than 0.015mm, and 4 times what the length of the knife is not more than cutting tool diameter. The fact that occupies SANDVIK company (RC) when undertaking high speed milling, linear velocity of rough machining cutting tool is 100m/min about, according to statistic, titanium is changed in use carbon nitrogen (TiCN) the integral hard alloy of coating establishs milling cutter (58H) and when finish machining and superfinishing, linear velocity exceeded 280m/min. The appearance of choice cutting tool of cutting tool appearance is main the basis is machined the exterior figure of workpiece, the element such as the dislocation frequency of life of cutting method, cutting tool and razor blade chooses. It is complex stereo curved surface when mould antrum for example when, efficiency of treatment of profile modeling milling is taller, special apply to model the rough machining of antrum, the milling cutter that its commonly used cutting tool has round bit, ball head milling cutter, can change head of ball of hard alloy of milling cutter of head of ball of milling head type and whole to establish milling cutter 4 kinds.How does milling cutter of corn of Yi Sika XQUAD use cutting tool of high speed cutting correctly? According to different treatment object, CBN and cutting tool of cutting tool of coating of logical choice hard alloy, diamond agglomeration layer.Mould of Fu Lan ground is special milling cutter of tall good crop uses high speed milling cutter of head of small diameter ball has mould outside precision work, normally 10mm of ＜ of diameter of finish machining cutting tool. The basis is machined material and hardness, chooses cutting tool diameter is different also. In cutting tool material choose a side, tiAIN exceeds cutting tool of coating of fine grain hard alloy lubricant condition is good, when cutting mould steel, having is better than cutting tool of coating of TiCN hard alloy fight abrasiveness can.Rich straps a product the cutting tool parameter with right choice of milling cutter of head of 4 blade ball, wait like the horn before losing. Concussion tenacity is fought when high speed machines cutting tool to ask Biputongjia is versed in capability of taller, heatproof concussion is stronger. Adopt a variety of methods to improve cutting tool life, wait like means of appropriate feed, feed, lubricant means, in order to reduce cutting tool cost. Use high speed knife handle. Application is at present most is HSK knife handle and cutting tool of clip of hot press fitting, the integral dynamic balancing that system of the main shaft after noticing cutting tool holds clip answers in the meantime.Knife handle of tall accurate HSK chooses appropriate cutting tool only and cooperate each other with the machine tool, ability achieves 1+1 ＞ in mould treatment process the ideal effect of 2, also be one of the most efficient ways that promote die manufacturer product competition ability.
