摘　　要：本文对部分发稳定氧化锆陶瓷(Partialy Stabilized Zirconia,PSZ)在高效深磨条件下的磨削力进行了试验研究,分析了各种因素对磨削力的影响,并与其它磨削方式的PSZ陶瓷作了比较和综合分析。分析表明:PSZ陶瓷在高效深磨条件下,当比材料去除率一定时,工作台速度的变化对磨削力的影响比切深的变化对磨削力的影响大;磨削力与普通磨削相比较大,比材料去除率是普通磨削的几十倍;材料去除模式以显微塑性去除为主,磨削工件表面质量较好。This paper describes an experimental research of grinding PSZ under high efficiency deep grinding conditions. The process is also compared with the conventional grinding in terms of removal characteristics and grinding performance. The results revealed that in the high efficiency deep grinding, workpiece feed rate has a larger effect on the grinding force than depth of cut at the constant material removal rate. Compared with the conventional grinding, it produced larger grinding force and specific material removal rate. The material removal for PSZ was dominated by ductile cutting, thus enabling a low surface roughness.
