Graph 1 range of products: Pass HSC-Line and T-Line two series, can get be usinged at rough machining or finish machining and the new cutting tool of character of all sorts of different milling cutter that are used at extremely accurate treatment. If use low-cost milling cutter, final result often not be to one's profit. Because use cheap cutting tool, the mould undertakes finish machining and polish even normally. As contrary as this, to accurate milling cutter, the price wants apparently a lot of more expensive. To reduce this kind of cost, company of German Dima cutting tool, put in the market at present have new series of two milling cutter, product of these two series is asking to decide according to different application on the price and function. To man-hour was added to high accuracy ground processes work and can design set of HSC-Line milling cutter in finish machining and finishing. The milling cutter series of cutting of this kind of high speed, its limits from the ball head milling cutter, milling cutter that establishs milling cutter and much blade milling cutter to be used till rough machining. To improve cutting performance, had coat to milling cutter. This kind of coating, the workpiece data that the company always should process in the light of place and those who have research and development, it is to be used at milling copper and aluminium a little among them special coating or the special diamond coating that cut black lead electrode with Yu Xi. Although be aimed at treatment hardness to amount to the mould steel of 66 HRC, the company has special milling cutter. At the same time coating improves milling cutter life about 200% , usable also will undertake working machining. Graph 2 requirements: When the steel model that makes intricate geometry appearance, the precision of milling cutter has conclusive sense to the quality of the mould. The milling cutter great majority that uses precision difference can increase the need of pair of follow-up precision work. To a few practical clew of high speed milling: A few ◆ is following to attention of machine tool need: 1, to ensure the circle with the smallest cutting tool beats, answer to install the knife handle of knife handle and machine tool main shaft taper hole to be blown clean. 2, the knife mix that has high speed milling should have higher balance quality. 3, the knife clip of milling cutter must want to have enough clamping force. 4, workpiece should install the workbench that is placed in the machine tool firmly. 5, when be being machined, cooling lubricating fluid or the effect that reduce air to want to have better cooling cutting tool. ◆ needs to notice the following to milling cutter: 1, should use as far as possible dangerous extend the milling cutter with shorter length. Graph 3 preparation offer: About 20000 store milling cutter in the storehouse of manufacturer home, so that can be in urgent when provide an user quickly. 2, better to obtain surface quality and use higher feed rate, always be preferential use suitable mill technology. 3, any moment should notice to eliminate optimally to cut bits. 4, choose appropriate cutting parameter according to material and cutting tool. 5, the cross section cutting bits of set cannot too small. 6, better to obtain treatment harvest, rotate speed and feed speed must want to be coordinated each other and cooperate. The knife handle precision of this kind of milling cutter is H5 quality class, the shrinkage fitting that makes cutting tool can undertake nicety matchs (the means of textual Schrumpfen is contractive, it is to point to outfit of milling cutter knife handle to bilge in heat here cold shrink in type knife clip -- interpret is noted) . Point-device cutting blade ensures the treatment that has tall nicety in his enterprise can score good gain. To this, undertake comparative with groovy milling cutter, the polish that uses accurate milling cutter to make machining needing again scarcely undertake sequel is machined, need to undertake polishing is machined no longer even. Graph 4 hardness circumstance: The cutter hub that makes by integral hard alloy makes milling cutter gains necessary stability, so that machine even if particularly hard, if hardness is as high as the mould steel of 66 HRC in that way material. The cutting tool petty gain that the milling cutter that offers series of fast service T-Line wants to compare HSC-Line series makes an appointment with 30% ～ 40% , but it does not have HSC-Line series milling cutter in that way very strict public errand. Of this series establish milling cutter and ball head milling cutter to suit to be used at rough machining and semifinishing machining. The milling cutter of two Line series uses the integral hard alloy that stabilizes highly to be made. Specific type can press long, short or little different texture to get the diameter is 0. The milling cutter of 3 ～ 20mm. Dima company worked two years to develop new milling cutter. Make to the mould for, milling cutter charge often expends items of expenditure importantly to look, new catalogue item can pass the milling cutter that chooses different precision, realized cost reduce. The client that is mould manufacturing industry provides excellent service, dima company can provide round-the-clock service, quick, rapid settlement the problem that the client encounters in producing a course.
