Crankshaft grinding treatment must come true high accuracy and cost-effective. Grinder of double head of a horizontal distributes stock two CBN millstones. As a result of OK and synchronous use, because this can shorten,exemple of – of circular basic cycle time accuses treatment to end namely inside the time that if a kind of 4 crock crankshaft are in,is less than dichotomy bell. The international competition of automobile production industry is more and more intense. And the demand of the technology to new car still is rising – reality to study the job makes clear ceaselessly, these mean cost. In addition, the country is discharged to the enterprise limiting value and rise further to what safety asks, increased the manufacturing cost of the enterprise. However, in view of intense market competition state, the way that thinks corresponding huff won'ts do in the market however. This to production, mean: Live to maintain up to now gain level, according to stannum of Mc-Kinsey(Mai Ken) the requirement of doctrine principle, annual the manufacturing cost of sedan must reduce 3% -- 4% . Design personnel wants constant ground to pay close attention to uses manufacturing technology: How to make ascendant cost falls afresh again? To this, crankshaft treatment is a very good example. The benefit of whole platform electric machinery and stability depend on its core component. Because this is in grinding process must the careful treatment of precision of class of micron of with a view to. Graph two 1 millstones are using: Two rise fall the synchronous treatment of bearing can shorten significantly circular handling time falls to rising twice the synchronism of bearing or headstock and company of Emag of 　 of outfit card treatment are passed use grinding machine of crankshaft of PMD 2 horizontal, can offer a quantity to order the grinding that do to machine plan personally to the user. This equipment regards a double head as grinder, be machined technically for sedan crankshaft and design. This equipment can be opposite two to rise through two millstones fall bearing or headstock undertake synchronism and outfit card machine – to be in to length the small part under 500 Mm also is such. From this, this enterprise that is located in Salach can be down crankshaft quote adjust. But be aimed at minor crankshaft part, still can offer without device of horizontal double head at present use. Say from in principle, personnel of research and development can rely on already mature technology. The foundation of PMD 2 grinder is Emag Naxos-unio and Emag Kopp 2 model equipment. Equipment combined safety of high-tech grinding technology and precision, efficient, craft and operation handy wait for a feature to be an organic whole. On equipment of PMD 2 grinder, two CBN millstones undertakes machining to crankshaft. To this, an oriented, linear electric machinery on X axis mixes the workpiece main shaft that grinder equipment deployed a direct drive, static juice online survey control system. Also can undertake on this equipment circularity detects with calibration. After measuring the job to be able to pass control instruction handily to end in bearing grinding by the user, carry out. Through using the software system that him company develops, can measure so that school plus is worth from inside error of the rest circularity. Follow-up production can get optimizing stage by stage (graph 2) . Graph model of 2 crankshaft grinder is compact. Set switch ark and container of the sources of energy on bonnet for example 4 crocks of crankshaft can be inside time of insufficient dichotomy clock grinding ends on the other hand, this technology adopted the feature that two millstones synchronism works. Craft of treatment of this kind of double cutting tool can be mixed according to different component different treatment job, offer extensive applied way to the user. Two rise fall bearing or a headstock rise with fall bearing can accept treatment at the same time. Can shorten from this the circular handling time of a component: For example 4 crocks of crankshaft can be inside the time of insufficient dichotomy bell be ended by treatment. Be in when necessary, grinding unit can be gone to by systole very narrow measure, can come true to fall to rising paratacticly thereby the synchronous treatment of bearing and headstock. Grinding axis and box of workpiece main shaft all have drive by direct drive ministry, this also can improve treatment precision and manufacturing efficiency. In addition, grinder equipment model is very compact, the design is agile. For example bonnet is compositive still electronic-controlled ark. With go up automatically the butt joint of makings device is unchallenged also. As cooling lubricant, can use emulsion or oil to taste. Emag company can make grinder equipment and user ask to match accurately. Of course, equipment compositive go up to an integrated product line, also be an important option. The technical program that uses the material on only station equipment and handiwork also can consider. Graph 3 operations personnel can enter grinder facility easily in CNC Milling
