Will replace facility of special machine tool through using CNC machining center, turning exercise also can be changed work for milling. Through applying the planar milling cutter that contains tangential clip to hold, milling can undertake inside the half the time that needs before, the service life of cutting tool can be lengthened however fourfold. Connecting general reason condition to fall, the special type machine tool that in the light of specific treatment task place designs should compare standard type machine tool apparently exercise is faster, efficiency is taller. But, machine tool of most special type can apply to circumstance of a kind of treatment only more or less, if need transhipment of through cargo, criterion cost is very high. And when using device of standard type machine tool, often need to make compromise on treatment efficiency, and the effectiveness sex of treatment and use flexibility criterion but taller. Because the function of milling machine or CNC machining center is rising ceaselessly, because of this cost costly special type machine tool cannot show an advantage more and more. This kind of circumstance also can be of course on cost hold a technology to bring an influence to cutting cutting tool and workpiece clip. Accordingly, new machine tool facility is purchased to replace facility of old special type machine tool in need, when the investment that requires when place especially is huge, make comprehensive consideration with respect to need. Be held to be in by clip SK50 main shaft the tigidity of the smooth milling cutter of the 85mm diameter that go up is strong, oscillatory small, achieves exterior quality is high, the service life of bit is long, treatment noise is low (graph 1) . Graph 1 be held to be in by clip SK50 main shaft the smooth milling cutter of the 85mm diameter that go up. Tigidity of system of this kind of cutting tool is strong, oscillatory small, achieves exterior quality is high, the service life of bit is long, whole of strategy of treatment noise low treatment updates the D ü Ker&Co that belongs to small and medium sized business.

The chief not long ago of KGaA company is facing such challenge. After making sufficient reflection to technology and economic respect, they decide pair of treatment strategy and technical equipment make whole change. This enterprise can be mixed in fluid technology, air feed production respect of water supply and equipment provides the product with various breed and service. Besides mould and enamel product, the company still produces grey mouth cast-iron with malleable iron, and include whole machining course. Company of D ü Ker has 470 stuff in Laufach factory and the works is distinguished in Karlstadt/Main additional have 250 professional. Machining is mixed in large turning, boring milling equipment and undertake on afore-mentioned special type equipment (for example turning and boring combination treatment) . Now, as a result of the special type equipment inside Laufach factory already ageing, must undertake rightly changing, because this company considers to change,the technology equips, change turning and boring to be mixed for milling namely boring. Can keep away from already so the special type equipment with high price, also invest the CNC machining center with lesser, stronger flexibility accessibly at the same time. The company ordered equipment of machining center of a Heller MCH 280 CNC very quickly. This kind of machining center still needs the workpiece clip with corresponding equipment to hold system and cutting cutting tool. The convention that company of D ü Ker decides to use a firm above all makes the same score milling cutter and withhold the Chamdrill boring cutter of Iscar company. Had accumulated the rich experience that uses about boring cutter on special type machine tool as a result of this company, because this also thinks,continue on CNC machining center continue to use this kind of cutting tool. But, the company discovered smooth milling cutter encounters bigger and bigger question very quickly. Because be placed on one hand,this is run a state not beautiful, cutting pressure is too great on the other hand, cause cutting rate thereby too slow, feed is lesser also. Accordingly, this company replaces possibility to what Iscar company enquires cutting tool. Iscar company recommends system of a kind of Helitang T490 milling cutter. System of this kind of tangential cutting tool has good edge appearance and with downy cutting and lesser cutting force be good at. Because existing at that time,clip runs a state not beautiful, angle of throw spends coefficient of big, cutting tool service life of small, cutting tool is brief differ with exercise security wait for a circumstance, accordingly, iscar company is first choose the smooth milling cutter that contains tangential clip to run a system, also changed treatment strategy at the same time and stipulated cutting is numeric. The diameter is 63mm respectively (left) with 85mm (right) Dao Rutu of Helitang T490 Ping Xi is shown 2 times. Graph 2 diameters are 63mm respectively (left) with 85mm (right) booked result can be achieved after milling cutter of peace of machining center of Nextpage of Helitang T490 smooth milling cutter can come true to undertake to flange component investment is used machining cutting tool neatly. Experiment continuously through two weeks, company of D ü Ker bought this kind of cutting tool to buy more cutting tool systems in succession later. The application of system of Helitang T490 milling cutter scores a success continuously, accordingly, this company bought quadruplet again this kind of cutting tool of diameter of 63 ～ 80mm. The versatility that the flexibility of CNC machining center adds smooth milling cutter formed a kind of perfect combination to realize the quick treatment of familial to all flange product. According to different specifications, DIN GGG flange accepts clip twice to hold on tray, undertake the plane of two sides or all sides is machined next. Still need milling at the same time 2.

The surplus of 5 ～ 4mm and boring gives 8 opening. Capacity of every batches of treatment is 3500 mostly. Use the smooth milling cutter of Iscar company, at present the handling time of flange needs only 7.

2s, 17 before and rather than.

7s. In addition, the service life of every razor blade of milling cutter is 80 workpiece only before, and improve 320 work now, grew fourfold. In the meantime, although feed increased one times, main shaft rotate speed rose 50% , but treatment noise had however substantially drop. All these should be attributed to pair of new-style smooth milling cutter use, no matter this kind of cutting tool is in charge respect, still be in other each respects, show scene. The dislocation razor blade of Helitang T490 smooth milling cutter has 4 very good and stable cutting wedge (graph 3) . The dislocation razor blade of graph 3 Helitang T490 smooth milling cutter has 4 very good and stable cutting wedge to be in data side, this kind of treatment basically does not have the place with insufficient what, can cover molding sand even. On the foundation that assembles the Helitang T490 that has bit of LNMC agglomeration dislocation smooth milling cutter to use the parameter such as time in 100min of limitative cutting force and every razor blade, realized longer service life and inferior razor blade to change frequency. The success of this respect results from the cogitative choice to cutting tool. Great majority of system of tangential cutting tool produces radial cut power only. Accordingly, it and before 45 ° smooth milling cutter is different, cut force is OK and direct action go up at the radial interface of device. Other good points still have bit ply big, treatment flow security is high, the cutting appearance of dislocation razor blade is complaisant distributing with milling cutter compact (distributinging feature of profit from tangent) etc. Graph 4 using newest generation tangent to make the same score milling cutter is implementation efficient with safe production make sure to D ü Ker the company is mixed for relevant functionary, change machining center and using system of another kind of milling cutter is special worthiness. Can come true to two work with 3 and can process a flange product that amounts to 100 different breed on manufacturing facilities. Process capability is OK from till hundreds of workpiece. Every work number can obtain 150 quantities, this is in before cannot be accomplish. In this respect, play of Iscar cutting cutting tool gave very main effect. Now, smooth milling cutter and boring cutter can be in to the combination on equipment is used and achieve whole to machine the effect. Installation cost is reduced significantly, and also need not use so much cutting tool. CNC Milling CNC Machining
