摘要

摘要: 采用4种不同磨料的砂带对ZrO2工程陶瓷进行对比磨削实验,并采用锆刚玉磨料的砂带进行正交试验,对材料去除量、工件表面粗糙度和砂带磨损量进行了测量,得出了ZrO2工程陶瓷最佳磨削参数。文章分析了在对ZrO2工程陶瓷进行砂带磨削加工过程中砂带粒度和磨削用量的不同对磨削加工效率、工件表面质量的影响。在磨粒切削加工模型的基础上,通过观察磨削前后陶瓷表面微观形貌分析了工程陶瓷的磨损机理。实验结果表明:随着磨削压力和砂带粒度的增大,工件表面粗糙度呈减小趋势;增加砂带线速度和磨削压力可在一定程度上提高材料去除率和磨削比,但超过临界值其表面易发生崩脆断裂;砂带线速度为19 m/s,磨削压力为15 N,砂带粒度为120#时,ZrO2工程陶瓷综合磨削效果达到最好。

Abstract: The abrasive belt grinding for ZrO2 Engineering Ceramics are carried out with four different abrasive belts. The orthogonal test with zirconia-corundum belt was to get the best grinding parameter, the amount of material removal workpiece surface roughness and belt wear were measured to get the best grinding parameter. The influence of abrasive belt granularity and different grinding parameters to grinding efficiency and workpiece surface quality in the all grinding process of ZrO2 Engineering Ceramics was analyzed. The wear mechanism of engineering ceramics based on the Abrasive cutting model by observing the surface morphology was analyzed. The results show that to increase the grinding force or the abrasive belt granularity can decrease the surface roughness of workpiece. With the abrasive belt speed or grinding force increasing, the material removal rate and the wear ratio increased to some extent, but brittle fracture easily occurred on its surface when exceeding the critical value; the grinding force is 15 N and the abrasive belt granularity is 120# at an abrasive belt speed of 19 m/s, the grinding effect of ZrO2 Engineering Ceramics was the best.
