Solid is worn abrasive high speed is abrade

5 are shown. Solid is worn abrasive high speed is abrade abroad is in 20 centuries 60 time development rises, 20 centuries begin to develop our country since 70 time. Solid is worn abrasive is abrade better land solved a tradition medicinal powder bead abrasive is slow fast abrade in exists much is short of owe. Its are the biggest the characteristic is can remarkable improve abrade treatment efficiency, and treatment efficiency is low it is the biggest obstacle that restricts traditional and abrade wide application, because this is originallying abrasive high speed is abrade appeared to get of people take seriously. College of Changchun grain industry from 20 centuries 70 time rise begin to be engaged in originallying abrasive is abrade the research of processing technique, held water to be engaged in the task group that this one technology studies technically, discussed wear in solid abrasive is abrade in, pair of abrade efficiency such as abrade pressure, abrade speed, cooling fluid and the influence that machine quality. Treatment object is confined to glass at that time, because this solid that discuss is worn abrasive is abrade the action of each parameter of treatment is to point to treatment glass commonly. These study effectively drove the promotion application of this one new technology. But solid is worn abrasive is abrade also existing a new issue, grind namely ongoing the conference in grinding appears wear away, this was brought about grind provided face form precision to drop, as a result is added precision of work area form drops. This asks people wants often seasonable nap to grind. Before medicinal powder bead abrasive is abrade, uses millstones processability is opposite for better. And use at originallying abrasive is ground abradely apparently solid writtens guarantee the abrasive of move pole wear-resisting. This makes grind a nap very difficult, because this restricted solid,wear the wide application with abrade abrasive. The teachers of college of Changchun grain industry begin early also to discuss grind wear away the rule, be aimed at spherical and abrade, discovered wear an expression of ideal tatty maths, also call rule of cosine wear and tear, reach according to this the rule grinds the distributinging regulation of a grind segment. After this, task group studied plane is originallying technically again abrasive is abrade in grind wear away, discussed grind a design problem. Grind however wear away with grind in abrade treatment provide and the opposite motion between workpiece and athletic contrail are having very close relationship. In 20 centuries for this the Li Mao of college of industry of grain of the Changchun at the beginning of 80 time and teacher mix 70 time end Mr. Liu Guiling discussed plane respectively again abrade and spherical and abrade in, grind provide and the opposite motion between workpiece, mr. Liu Shaodong begins to be ground from mechanical angle analysis wear away reason. These research are to assume the rotate speed of workpiece is foregone, and it is changeless. Accordingly, these research achievement are abrade to drifting in, the circumstance with workpiece sealed rotate speed, appear loath, but these research achievement drift for further research abrade grind wear away the rule laid a foundation. Take a person 20 centuries 80 time, our country is engaged in originallying the person of abrade research adds abrasive gradually much. Professor Cao Tianning of university of Professor Cha Liyu that prior has university of Beijing grain industry, Zhejiang waits. They discuss abrade mechanism, abrade craft already, discuss again grind with the opposite motion between workpiece. Pei Qingkui, Lin Jinwen, Zhang Liming, king is emerald green later the scholar of a batch of experts such as Di, Wang Kai, Xin Qiming is engaged in originallying abrasive is abrade the research of processing technique. The person such as Hua Jinsong and Wang Zhongqi still will originally abrasive is abrade the technology is fetching polishing domain, study new-style solid is worn abrasive casts mating plate, use at undertaking high speed polish. The person such as Zhang Gongxia considered technically still to using solid to wear abrasive casts mating plate to undertake polishing in, how to assure the even purify problem of workpiece material. Not only expert scholar of home is engaged in originallying abrasive is abrade the research of this one technology, and abroad also the research that somebody pursues this one technology. David F.

The person such as Edwards studied diamond is originallying abrasive muller manages, solid is worn abrade treatment workpiece already machined abrasive exterior surface roughness and the metabolic rule that destroy a layer to wait. The treatment data that its study is glass, the key is to discuss workpiece to already machined exterior surface roughness and material purify quantity to follow the metabolic pattern of abrade handling time. They still compared the result of different cooling fluid, discovered the surface surface roughness and destroy a deepness to have one constant relation, this makes people can be worth the purify deepness that will issue working procedure certainly according to workpiece surface surface roughness. At present abroad takes the improvement of abrasive function seriously relatively, and bolus piece the research of the technology that make, discuss how to avoid bolus piece delamination and break, avoid bolus piece in interfuse air, the uniformity that raises abrasive and bond. Wear to improve solid better abrasive is abrade the effect, raise bolus piece quality, the person such as the JuichiIkeno of Japanese Tokyo university still considered to use electrophoresis deposit legal system to make the high quality, fine ball that wear bead piece, the pill that adopts them to develop piece machine silicon chip, make machined exterior quality to get very big improvement, achieve 8nm (wave crest - trough is worth) . Return somebody to adopt diamond pill piece abrade treatment is spherical and blame is spherical, rose to machine efficiency, obtained very good result. But people is noing doubt to be in abrasive float is abrade in nap grinds a research that still lacks deep person, and provide because of grinding wear away reach wear a face scraggly easy to workpiece generation is bumped, attaint workpiece, at present so foreign solid is worn the rotate speed of abrasive muller still does not calculate tall, although improved abrade treatment efficiency, but not ideal also. The solid that Peter Wolters company of Germany produces is worn abrasive muller, grind a top rotate speed to be 148r/min. In the absense of provide to grinding wear away the proper control technology that intensity distributings, make people still wants often nap is ground, the face form precision that provides with assuring to grind and by the face form precision of treatment workpiece surface. This wastes abrasive already, increase auxiliary man-hour again, grind a worker to operated technical level to raise very tall requirement to nap at the same time. Because this perfects solid further even,wear abrasive is abrade processing technique. Although before people is worn to solid abrasive is abrade had a lot of research, provide to grinding especially wear away undertook deep person is discussed, but still fail from go up at all solve grind wear away problem. Because current muller often uses float,this basically is abrade, grind provide and in workpiece both, one is to rotate actively, it is foregone that its move; And another is float is on its, rely on abrade cutting force to drive turn subsequently, also call float (we say this is planted abrade to drift abrade) , it is sealed that its move. A lot of people just were discussed in the past grind provide and workpiece moves to all have the opposite campaign between workpiece to be ground below foregone circumstance. Because this and float are abrade the condition is abhorrent, because this is opposite,the direct action with abrade float is restricted. Drifting abrade in the analysis grinds a workpiece opposite motion is more difficult, because this people is forced to do a few hypothesis, in an attempt to gives this one sealed campaign. The simplest hypothesis is size of both rotate speed equal, way is same. And somebody is opposite the rationality of this one hypothesis had a proof, but did hypothesis again before the proof, grind suppose provide and workpiece both drifts mediumly master piece uses an abrade cutting that gets another driving link only, and suffer external the impact of the element such as attrition obstruction quadrature is very little, negligible. In fact abrade treatment is a kind of nicety and superprecision, taller to requirement of work area form. Although discussing the factor that grinds the oversight when having the opposite campaign between workpiece very not important, the error that cause is very small, but because this error is to accumulate disperse the internal heat with sudorifics model, accordingly as treatment undertake, grind a face form error with workpiece to will increase gradually, this is very adverse to treatment. Somebody ever was opposite float is abrade medium float motion was done suppose improve. But existing oversight element, be in theoretic, cause inevitably grind provide and error of work area form.
