At present picture of international car market flourishs, increase impetus fierce interest. Make clear according to the data of Polk of American market research organization, photograph of car sales volume grew 3% than 2010 2011. A lot of cars and task of supplier company production are busy, phasic flourishing. Face the order that following sb's heels and reachs, be opposite inside brief period on one hand " appropriate of essence of life is produced " (turn production in time) spare parts demand will be climbed considerably litre; Also posed grim challenge to how closing the quality of good part on the other hand. One applies example to prove: Through using the machine tool technology of new structure, can meet above challenge easily not only, and can think those who raise engine is overall quality rises to urge action: This is the crankshaft of unprecedented and camshaft innovation grinder. Use dust the leap that the technology of the synchronous grinding that prop up of mark research and development can make the manufacturing efficiency of crankshaft and camshaft manufacturer raises – of hundred 70 to realize an amount. It is with China exemple: Although the car market of China of period of time rises to put delay somewhat recently, but compare with phase of world other market, this " central country " still acting part of world economy bibcock as always. Car output of China was returned 2009 is 1 1000 1 million 1, to 2010 its car output already grew 1 1000 1 million 4. Although,grew 2011 somewhat slow down, but car total output still achieves 1 1000 1 million 5 (data origin: PwC, statista) . Meanwhile, the import volume of car component, engine or gear-box assembly also is in rapid growth. Estimate according to German commerce and the foreign trade expert that invest an orgnaization, china already made the world country of the 3rd big entrance. Face so rapid growth, people can'ts help wanting to ask, the manufacturing shift that how should reach high quality effectively through economy will answer? How should the manufacturing base outside Chinese churchyard plan to produce, can ability satisfy this growth requirement? Crankshaft and the outstanding example that camshaft machines are well-known, because crankshaft and camshaft are the two core spare parts of engine, and the characteristic in view of its geometry structure and dimension, manufacturing technology is particularly sophisticated. In the treatment process of these two spare partses, because grinding craft must assure the dimension of package, holding in whole treatment catenary so special position. Grinding is very additionally time-consuming, precision requirement is very slashing also, processing long and thin rod especially kind when, because workpiece is machining rigid difference of direction, often need to configure many centers to wear so will stabilize workpiece. Accordingly, after work is steady, the feed when treatment still needs to be controlled lesserly, be in especially eliminate inaccurate when actual error. And feed is small, mean metre tall, yield low. "We are in axis of vertical of research and development kind when grinding craft, go up in this one problem very left time one time. Train of thought of our research and development is the outside force that workpiece brings to bear on when reducing grinding as far as possible. Only such ability raise feed " , aimakesalahe explanation of presiding apparitor Dr. Guido Hegener says machine tool limited company. Dust machine tool of mark VTC 315 DS brings to bear on the outside force of workpiece is small configured dust the synchronism of newest research and development supports mark the machine tool of VTC 315 DS of grinding technology, decreasing respect of little work outside force to obtain major breakthrough. The principle of this one new technology is the emery wheel that used two mutual contraposition, the moving direction of the emery wheel when machining crankshaft or camshaft just contrary. Because emery wheel is in,two side check work each other buy, so when synchronous cutting, the radial load each other of feed direction is quits. The machine tool configured tie-in of numerical control of a NC at the same time, it supports the one end of workpiece, so workpiece won't deviate at any direction, and tangential force also is eliminated. "This design reflected favorable openly effect in a lot of respects " , mr Guido Hegener says. "On one hand, because the tigidity of workpiece clamp is good, machining camshaft or crankshaft so when this kind of long and thin workpiece, also can use extremely tall feed; On the other hand, two emery wheel at the same time grinding, compare with current and common grinding craft photograph so, shortened greatly handling time. " the good point that the cam outline with geometrical complex form also can use technology of the synchronous grinding that prop up to undertake synchronism machines Nextpage vertical structure improves treatment economy is dust the another design tenet that mark grinder emphasizes. Use VTC 315 DS to process a rod kind when, workpiece is inside the machine tool vertical clamp. Workpiece main shaft (the head is worn) decorate in machine tool upper part, rear push frame is decorated subjacent. Workpiece is undertaking below this kind of condition complete set grinding is machined. As a result of workpiece vertical clamp, fall so bit is very good. Scrap of cutting fluid along with can be sent treatment area by simple and efficient ground. Additionally cutting fluid does not shed classics airframe, so cutting fluid temperature won't produce wave motion in whole grinding process. "This also is a when decide to machine quality main factor, deliver because of the heat inside equipment very few " , guido Hegener explains. At the same time because use vertical structure, the operation of the machine tool is convenient, pull current Cheng is efficient. Besides, use machine tool of VTC 315 DS to still can use tailor-made end panel drive elliptically, simplified greatly process of transhipment of through cargo. Produce a system to what camshaft undertakes complete set machines: Adopt platform of VTC machine tool entirely to grinding from soft treatment. What experience is there after the user of camshaft of 4 crocks of engine with dimension extremely tall precision used technology of the synchronous grinding that prop up? "The information of the user feedbacks quite the front, first-rate " character of Guido Hegener deeply touched, "Use principle of this one grinding to suit to machine the biggest length particularly the gear-box axis under 600 millimeter, gimbal axis, pump shaft or trunnion shaft. When machining these spare partses, new grinding technology showed huge advantage in efficiency respect. Compare with photograph of traditional grinding craft, can shorten when the pitch time of new grinding technology is maximum hundred 70. " machine quality to also rise somewhat meanwhile. Among them typical case is new grinding technology the application in machining cast of 4 crocks of camshaft. The main shaft neck of this camshaft divides ordinal treatment, every sequential grinding time is 5 seconds. Although grinding time is short, but the round jumpy precision of treatment can assure to be inside M of 10 μ however. This precision result greatly the tolerancepublic errand limit that prep above allows, apparently good also the treatment result at traditional grinding technology, do not allow doubt this is a qualitative leap. Double emery wheel of principle of technology of the synchronous grinding that prop up is synchronous " treatment " technology of the camshaft synchronism grinding that prop up applies to round treatment not only, also apply to domain of the treatment that be not a circle, it is OK to use it for example the cam wheel pair that synchronism machines 4 crocks of camshaft, that is to say 4 emery wheel are at the same time on a camshaft grinding. Used this technology to shorten greatly not only handling time, also improved the outline quality of cam at the same time, brought double profit for the user. Use dust mark craft of this one innovation, can make the end panel of – of catenary of whole treatment craft of camshaft treatment, car, mill, deep bore, round grind and be not a circle to grind – to hold clip in vertical next finishing. Tremendous market business chance a variety of advantages in view of new technology, dust mark company controller thinks it has tremendous market business chance should be the thing in expect. Actually the advantage of technology of the synchronous grinding that prop up still reflects in other respect: For example shorter handling time also means specific power consumption to reduce. "Compare with photograph of traditional processing technique ' odd a specific power consumption ' reduce apparent, its are to be an user as a result managing operation expenses " , mr Guido Hegener affirms say. Compare with photograph of horizontal machine tool additionally, the machine tool of vertical structure is covered an area of small. "Craft economy is efficient, the operation goes to the lavatory simply, quality is excellent and outstanding the good point that – is supporting grinding technology to have these traditional techniques to cannot be had as a result of synchronism, the cosset that it is sure to make the market " , mr Guido Hegener is full of self-confidence, complacent.
