研究纳米陶瓷材料磨削加工磨削力、磨削温度及表面粗糙度等表面特征,获取高质量的加工表面,是该工程材料得以广泛应用的重要前提。对纳米ZrO2陶瓷材料平板施加二维超声振动进行磨削,超声振动产生的空化作用、泵吸作用以及涡流作用,能一定程度上改善材料的加工性能、提高加工表面质量,实现纳米陶瓷材料的精密高效加工。结果表明:二维超声振动磨削与普通磨削相比,实际磨削力、磨削温度相对较低且随切削深度增加增长速度较慢;选取不同的磨粒粒度对纳米陶瓷材料进行磨削加工,超声振动加工的表面粗糙度值与普通磨削表面的粗糙度值相比相对较小。
It is an important prerequisite for the extensive application of this engineering material to study the surface features such as grinding force, grinding temperature and surface roughness of the nano-ceramic material for grinding and to obtain the high-quality processed surface. The application of two-dimensional ultrasonic vibration to the plate of nanometer ZrO2 ceramic material for grinding, cavitation by ultrasonic vibration, pumping action and eddy current can improve the machinability of the material to some extent and improve the quality of the machined surface to realize the nano-ceramic material Precision and efficient processing. The results show that compared with ordinary grinding, the actual grinding force and grinding temperature are relatively low and the growth rate is slower with the increase of cutting depth. Compared with conventional grinding, the grinding speed of two-dimensional ultrasonic vibration grinding is slower than that of ordinary grinding. Processing, ultrasonic vibration processing of the surface roughness and roughness of the ordinary grinding surface value is relatively small.
