High speed of brief introduction of high speed treatment is machined (HSM) already not simple be shorten one kind manufacturing time and the technical innovation that raise workpiece precision, it is cogent already rise make the manufacturing strategy that improves productivity for the enterprise. This kind of politic straight opposite produces cost and manufacturing time, the result should win the work of high quality not only, should improve manufacturing efficiency more. The core that high speed machines is through raising main shaft rotate speed and feed, acquire better treatment quality, this action initiated the beginning with new processing technique. Apply at Bao Bi treatment, get exceeding slick treatment surface, the advantage such as rate of tall metal purify already got be admissived extensively. This kind of technology can be used at nonferrous metal not only, more apply to hard steel of temper by dipping in water and material of other difficult treatment, apply extensively in the industry such as aviation, mould, small part and medical treatment. Although the concept of high speed treatment had put forward for a long time (19 centuries 20 time appear first) , define to it however very ambiguous still. 1931, carl Salomon machines high speed the definition to be first: Cutting speed compares traditional cutting tower above 5 ～ the treatment of 10 times moves. However today, we know high speed treatment means rotate speed of tall main shaft not just, it is a kind of overall situation strategy that raises productivity and managing cost more. The application that high speed processes a few special properties that manage aluminium alloy, for example car spare parts, small-sized computer spare parts and medical treatment equipment, need achieves rate of purify of high speed metal in treatment, also caused the demand that machines to high speed. In aviation domain, it is the wing of raw material and airframe with aluminium alloy, because treatment wall is very thin, also rely on what high speed machines to apply, rotate speed of your main shaft still can achieve 5000 ～ 15000 R/min below the premise of tall feed. Another mould industry is milling of high speed cutting uses a field. It asks cutting tool is processing tall hardness material and weaker data, it is the black lead electrode in processing EDM trade and cupreous electrode even when, can satisfy strict public errand, high accuracy and fast face quality. In the meantime, high speed treatment realized mould industry to use small-sized cutting tool, small cut deep the possibility that has machining, also make narrow groove and complex model the treatment of the face can choose milling to replace report to machine. Besides, the bright and clean face that high speed treatment gets returns leave out the link of artificial polish. Afore-mentioned application have level of main shaft rotate speed not only, need to a steady craft support shows actually more. Involved aspect includes tool system, technological process and control program, and these differ the requirement that machines with the tradition very far. Below a few circumstances, the position that still needs to understand a machine tool to fall in rotate speed of different main shaft to the choice of craft. Considering the norms of different machine tool, be aimed at the high speed treatment of different workpiece to come true, in the system that craft architect wants to will machine each medium link interconnected system to add up to a balance. This requirement architect considers the following important segment: The alloy brand of cutting tool of cutting tool material and cutting parameter are acting important role in craft. Also accordingly, yi Sika developed IC08 brand hard alloy -- one kind does not have coating, exceed fine grained, hard alloy brand, use at the high speed treatment of nonferrous metal. Besides, yi Sika returns research and development IC903 brand alloy -- a kind of cobaltic content is of 12% exceed coating of imperceptible grain, TiALN PVD, those who have tall tenacity, tall wearability is idiosyncratic, apply to hard steel of temper by dipping in water (62HRc above) , titanium alloy, nickel radical alloy and stainless steel. These cutting tool pass special geometrical appearance and design of the chamfer that break bits, apply to high speed treatment. Besides, high strenth material pledges your cutting tool can resist high-frequency wallop, also have inferior hot coefficient of expansion at the same time. Knife handle -- the breakthrough balances a problem to wait for accessory system to knife handle, influence high speed adds what work efficiency leads to electric machinery of main shaft, layshaft, drive, knife handle and cutting tool wait. Main shaft is crucial element, accordingly, mix to keep efficient high accuracy, must assure to beat be fallen to come lowest. Jumpy value is less, the life of bit is longer also, it is especially in high speed treatment, jumpy value size is attached most importance to especially should. On cutting blade the value of TIR should be controlled it is in 10 μ M. Jumpy value every increase 10 μ M, cutting tool life will decrease 50% . Although cutting tool, knife handle and main shaft maintain height to balance a gender, also can produce a few not stable ingredients. One of elements are knife handle and main shaft clearance, often exist between both cannot the span of oversight. And this clearance is likely even corner scrap and dirt. In be machined actually, a rotate speed is 20000r/min establish milling cutter, need to adjust dynamic balancing only to 20g/mm. To assure accuracy to the greastest extent, yi Sika research and development shrink collet (SHRINKIN) -- bilge through heat cold shrink the system of principle implementation clamp, make through this means hard alloy establishs milling cutter clamp to achieve taller tigidity. New clamp system was obtained taller torsional, smaller beat and taller repetition locates precision. The knife handle of shrink collet is long and thin, can offer more length alternatives, achievable also deeper model antrum mill and the milling that have sidewall interference. Yi Sika supplies the complete set equipment of shrink collet for the user, include the heater of unique design, deserve to have heat movably handle. Heater is measured from the temperature with advanced belt control apparatus, handlers but simple, undertake operating in machining center or tool room conveniently. Yi Sika offerred another alternative for the high speed treatment of high accuracy is dynamic balancing knife handle (BALANCIN) -- dynamic balancing regulating system is installed on knife handle. Series of dynamic balancing knife handle has a certain number of advantages, if can go up to numerate directly in knife handle,the dynamic balancing of high accuracy is worth, regulating system can be used at all sorts of dynamic balancing appearance to wait conveniently. Additional, this knife handle can undertake dynamic balancing and static balancing adjustment, filling difference value achieves 61g/mm. Besides, to ensure high speed machines precision, we still need to consider order of the structure of main shaft, thermal stability, motion, the element such as hardware, centrifugal dilate, hot dilate and vibration. Mention oscillatory, it originates likely the contact of cutting tool and workpiece, or the resonance that cutting causes, because centrifugal master piece is used on lopsided cutting tool or knife handle,also be likely. Control is oscillatory, can improve treatment precision and efficiency not only, also can prolong the life of machine tool main shaft and cutting tool. Vibration still can affect the surface bright and clean degree, cause blade of cutting blade collapse and generation noise. What speed brings is efficient the stability of the athletic condition of machine tool tool and whole system decided to be machined the quality of workpiece. Besides, the design of cutting blade, treatment parameter and the systematic condition that impose man-hour decided the exterior quality of workpiece. This also is meant, will for a long time look, an excellent treatment facilities that supports high speed cutting can achieve first-rate return rate. Use steep drive electric machinery the electric machinery of drive of ball guide screw than the tradition is OK greatly improve manufacturing efficiency. And the because machinery cooperates,causes error in using linear electric machinery to be able to reduce system of drive of guide screw of similar and traditional ball. Using advanced high speed processing technique to be able to be regarded is pattern of a kind of management. It needs each link in integrated, harmonious treatment, those who will achieve treatment efficiency is the biggest change. The processing technique that the market competition of conclusion cruelty asks to update and solution, high speed is machined even if implementation is efficient and what save finished cost with season is outstanding example. Although raised taller requirement to machine tool equipment, but what high speed treatment gives us is endless interest. It is us managing manufacturing time, decreased to machine measure (for example artificial polish) , still assured to machine precision at the same time. Although we had had certain knowledge to high speed treatment, but for better quality and lower cost, the research to it and development must proceed. CNC Milling CNC Machining
