碳化硅陶瓷高效端面磨削试验研究

Experimental Study on High Efficiency Face Grinding of Silicon Carbide Ceramics

碳化硅陶瓷材料多采用小磨削深度的传统磨削方法,磨削效率较低。采用金刚石砂轮对碳化硅陶瓷材料进行了端面磨削试验研究,选用低进给速度和大磨削深度,探究了不同磨削参数对磨削力和磨削表面粗糙度的影响规律,分析了磨削表面的损伤形式,进一步验证了碳化硅陶瓷磨削加工材料去除机理。试验结果表明,端面磨削方法可以进行大切深的磨削加工,砂轮预紧力对磨削力和磨削面粗糙度有一定的影响作用。

The grinding method of Silicon carbide often uses small grinding depth with low efficiency. The face grinding experiment method with lower feed rate and bigger grinding depth is done to explore the different factors＇ impacts on grinding force and surface roughness. The grinding damage of silicon carbide ceramics is analyzed. The result indicates that the face grinding method can be used with bigger grinding depth and the preload force of the grinding wheels has a certain effect on the grinding force and surface roughness.
