Consider to make clear, the diamond millstones that is C100 for D64 and density by the granularity of synthetic resin agglutinate can achieve lesser coarse coefficient and better exterior quality to use diamond millstones and add note abrade oil to change silicon pottery and porcelain and material of alumina pottery and porcelain to undertake to nitrogen, still have very large development latent capacity. Accordingly, the purpose of each research is the efficiency that continues to improve grinding technology below the premise of character of attend to material. Use the data of efficient pottery and porcelain that regards cut as material, the product is replaced in what specific application can make material of groovy rolled steel or hard metal in the domain. Be in especially efficient cut circumstance, can be accelerated because of cut and feed speed and achieve higher time / size specific value, thereby great improved manufacturing efficiency. Although material of pottery and porcelain has advantageous character (mix like admirable high temperature hardness, wear-resisting anti-corrosive characteristic) , but because its are made,maintain cost very tall, often abandon material of pair of pottery and porcelain because of this people use. The character that notices material of pottery and porcelain in grinding exercise because the character of material of pottery and porcelain (the hardness with very tall such as, brittleness, hot oscillatory sensitivity) , special caution needs in machining a process. Differ with hard metal, material of pottery and porcelain because its brittleness is big, not quite have be out of shape through plasticity come the pointed department position that burnish appears. Accordingly, treatment exercise often wants attend to to be short of to this kind break but model is characteristic. When grinding processes data of pottery and porcelain, by the diamond millstones of synthetic resin agglutinate because its hardness is tall, behave thereby outstanding. Use synthetic resin adhesive, can achieve relatively lesser treatment power, reduce millstones wear away degree, make workpiece achieves better exterior quality and appearance precision. But, the millstones of synthetic resin agglutinate is differred as a result of heat conduction function, because this is in grinding flow, can appear very high temperature. Agglutinate of pottery and porcelain is different. Because it has better hole sex, because this is in grinding process,can realize inferior temperature. Normally it also has taller effective hardness. Study working purpose, below the premise that is the character that should noticing material of pottery and porcelain, improve the efficiency of grinding flow. To study a purpose, the with agglutinate of a kind of pottery and porcelain diamond millstones that used agglutinate of a kind of synthetic resin, its granularity is D64, density is C100, use technology of circumferential plane abrasion, be in add on direction instead pour abrade oil (graph 1) . What what want exploration is, of agglutinate type fluctuant, can be versed in to adding force and quality of surface of material of pottery and porcelain bring how old influence after all. Considering simple modelling, used nitrogen to change silicon pottery and porcelain (Si3N4) with alumina pottery and porcelain (Al2O3+ZrO2) SNGN120408 dislocation razor blade, as the work that needs treatment, with hereat the research activity of fundamental sex, with obtaining simple technological process trends mechanism is mixed but reduplicative grinding process. Graph the experiment of circumferential plane abrasion of razor blade of dislocation of 1 pottery and porcelain is tectonic in the series test that the grinding force in technological process of influence of Nextpage feed speed produces change in feed speed, it is normal to use 3 components dynamometer to be opposite grinding force and grinding tangent force undertook determining, in order to obtain information of cutting tool bear. The graph is shown 2 times when changing material of silicon pottery and porcelain and material of alumina pottery and porcelain to undertake grinding is machined to nitrogen, grinding force and two kinds of use relationships of the feed speed of millstones. Can see total impact from which, namely feed rate rises, criterion flow grinding force also is increased. Accelerate as feed speed, the volume amount of unit grinding time also can be increased automatically, because millstones can wear the stuff of same size inside shorter time,this is. As contrary as this, when using method of agglutinate of pottery and porcelain, flow grinding force wants the grinding power that leaves under circumstance of synthetic resin agglutinate apparently. Its are main of the agglutinate material that the reason depends on using wear away mechanism each are not identical. Because agglutinate of pottery and porcelain has better hole sex, because this is more advantageous than synthetic resin. The grinding force contrast that uses the grinding treatment that material of different pottery and porcelain has makes clear as a result, the grinding force that appears when grinding nitrogen changes silicon pottery and porcelain should be more than the grinding force when grinding alumina pottery and porcelain. Material of different pottery and porcelain pledges the reason of the difference of grinding force numerical value between can explain because what different material composition and different physics character cause,be is. Graph the quality that the influence of type of 2 millstones agglutinate to grinding force can carry work to the result of technological process tries assess. The numerical value such as the surface roughness that can use coarse coefficient, place to be measured to this and arithmetical and average surface roughness will undertake. The relation between the exterior coefficient change that the graph shows face of grinding of workpiece of pottery and porcelain 3 times and the different feed rate that use millstones of type of two kinds of different agglutinate. When grinding nitrogen turns material of silicon pottery and porcelain, if feed speed is increased, the coarse coefficient that measures can present ascendant state slightly, this and grinding force are basic and corresponding. And when material of grinding alumina pottery and porcelain, although have two kinds of different feed rate, coarse coefficient is relatively stable however, but when numerical value should change silicon pottery and porcelain than nitrogen tall. This is main end falls off at different material character and different material mechanism. The material of material of pottery and porcelain falls off OK and perforative till,be out of shape from plasticity dinkum fragile the whole process that stop. The main reason that uses millstones of agglutinate of pottery and porcelain to cause poorer surface quality depends on in front what states place uses different agglutinate data is different wear away mechanism. Graph the mensurable influence of type of 3 millstones agglutinate to quality of grinding workpiece surface studies the result makes clear, the granuality of synthetic resin agglutinate is the diamond millstones of C100 to be able to achieve lesser coarse coefficient and better exterior quality for D64, density. And the grinding force with the millstones lesser generation of agglutinate of pottery and porcelain, this lowered the rate of total heating power bear on workpiece apparently. CNC Milling
