氮化硅陶瓷镶块低粗糙度磨削的研究

提出氧化铝砂轮磨削陶瓷表面的加工过程是砂轮磨粒与工件表面凸峰的碰撞－碰撞与摩擦共同作用－摩擦抛光。对砂轮速度，工件转速、砂轮横向进给量、光磨次数，陶瓷材料硬度以及切削液等因素对表明粗糙度的影响进行了分析，表明氧化铝砂轮通过挤压和磨削抛光作用使陶瓷工件表面的粗糙度得到显著改善，实现了在普通磨床上对陶瓷材料的高质量加工。

Study on Low Surface Roughness Grinding of Silicon Nitride Ceramic Glutting

This paper first presents ceramic surface grinding process using aluminum oxide grinding wheel,which is finished by the collision of abrasive particle with the apex of workpiece surface,and by the collaborative affection of collision and abrasion,and by the process of burnishing.Then the authors analyze the affection on surface roughness of such factors as the speed of grinding wheel ,the rotational speed of workpiece , the amount of feed in traverse direction of grinding wheel , the numbers of burnishing,the hardness of ceramics and the performance of cutting fluid. The experiments show that the surface roughness of porcelain workpiece is remarkably reduced by squeezing and polishing of aluminum oxide grinding wheel ,and high quality machining could be achieved by plain grinding machine.
