Grinding is to use not certain the crucial point to come the treatment of cutting. Current grinding technology, raised new requirement to grinder equipment not only, and also raised taller requirement to abrasive tool. To raise precision, improve efficiency, reduce cost, each abrasive grinds a manufacturer to be made hard in every respect, will suit and develop new product, increase their respective competition capacity. Combine our country's current actual condition, I think the development trend in the future has the following sides: The application of the CBN that develops bond of pottery and porcelain further and diamond emery wheel produces the German Krebs with special famous emery wheel with the world&Riedel company is exemple, its exceed hard abrasive - emery wheel of CBN/ diamond pottery and porcelain in recent years, annual grew with 40 ％ speed 2005 especially with the speed of 20 ％ , enough sees clearly, abrasive grinds provided development tendency is Xiang Chao hard abrasive - the way of emery wheel of CBN/ diamond pottery and porcelain develops. Sex of not the thermal stability of abrasive of its reason CBN, close iron, hardness is mixed high wearability is good, with the emery wheel that it will come to produce, grinding efficiency is tall, treatment surface quality is good, process harder work especially, will have wider application. The emery wheel of the bond of pottery and porcelain of CBN, will compare the application with colophony wider emery wheel. The CBN emery wheel of pottery and porcelain can undertake correction by factitious need, when working at the same time give out heat not easily, this is the condition with essential production of large quantities of quantities, high accuracy, also can press the demand that processes work, produce the emery wheel with different hardness, will get used to the need of treatment. The bond of pottery and porcelain with new research and development, produce the high speed emery wheel of atmosphere aperture. To bond and filler grind to exhibit and choose correctly, produce the emery wheel of atmosphere aperture, want to have better wearability at the same time. Atmosphere aperture emery wheel is process, poriferous to deep grinding and heavy-cut grinding and atmosphere aperture is indispensable, it is carried cut bits, carry cutting fluid to arrive osculatory area, shun burn work, particularly right figuration grinding and accurate grinding, in order to assure the figuration sex of emery wheel. High speed emery wheel, the working rate of 60 – 80m/s, to CBN emery wheel its job rate is more than 100m/s to already was used morer in Europe, especially a few special grinding machine, if the crankshaft of Junker and camshaft grinder use Krebs&The emery wheel of Riedel, its job rate achieves 125m/s, its characteristic is unit time those who attend grind a much, efficiency the quality of tall, surface is good, prolonged the life of emery wheel. The following graph can see the scope of application of CBN emery wheel. The much face emery wheel with manufacturing geometry complex form is mixed according to the property of abrasive wear bead, special to treatment workpiece undertakes abrasive grinds bead to produce emery wheel mixture, with different treatment the face differs the emery wheel that wears bead, a Krebs with unique at present mature technique&Riedel is on crankshaft grinder, be in same piece on emery wheel, two different faces wear bead with different CBN abrasive, this kind of emery wheel has been in the world a lot of engine plants are applicable. German Krebs&This innovation of Riedel company, greatly improved manufacturing efficiency, reduced sheet manufacturing cost. The crankshaft that suits large quantities of quantities particularly, camshaft and slideway grinding are produced. The quality that rise and stabilizes manufacturing emery wheel produces the emery wheel with stable quality, it is each manufacturer place is striven for those who accomplish. The ingredient that because produce the complexity of emery wheel, uncertainty and influence emery wheel,produces quality is very much, each approve the emery wheel that gives heat, its quality has fluctuant, each production manufacturer is in hard, as far as possible make quality wave motion is reduced, in order to reduce the adjustment of the user time. The similar product that the user orders, this batch Alexandrine approved grinding situation is different, this also is the place with abrasive tool and other different cutting tool. Of colophony bond exceed hard abrasive emery wheel to trim acute defect to avoid to amend, investigator is being developed " from acute " emery wheel. Of metallic bond exceed respect of hard abrasive emery wheel, amend Xiu Rui in research with laser and electrolytic method. These mature with needing a technology. Improve knowledge of be transferred to civilian work, since grinding is,use inaccuracy to decide edge to come for user choosing good emery wheel the treatment of cutting, a lot of do not decide the element affects his to produce, to the manufacturer home of large quantities of quantities, optimize its grinding craft, increase production efficiency, reducing cost is very important. This also asks to grind a supplier to want to have very good technology service. When choosing emery wheel for the user, want to know its workpiece parameter, with the requirement that should achieve, according to emery wheel of its parameter choose and buy, also be the lowermost requirement that good applied business raises to the supplier. The choice of abrasive mould, cannot be the choice of its appearance only, more important is the basis manufactures technology, its suit to machine the abrasive choice of workpiece. With the word of the industry: Had chosen correct abrasive and grinding method, had completed half treatment. Raise the person that abrasive mould is sold and the professional level of the person that apply, the professional level of the person that sell especially and after service, it is the mainest factor to choosing the vendor of emery wheel.
