摘要
采用树脂结合剂金刚石砂轮磨削氧化锆陶瓷套圈内圆,分析了各磨削工艺参数包括砂轮的粒度、线速度(vs)、轴向振荡速(fa)和径向进给速度(fr)对氧化锆套圈内表面粗糙度的影响。利用正交实验,通过回归分析得到加工表面粗糙度的回归方程。实验结果表明,金刚石砂轮的粒度是对加工表面粗糙度影响最大的因素,随着砂轮粒度的减小,加工表面粗糙度呈明显下降的趋势,而砂轮的线速度、轴向振荡速和径向进给速度的变化对加工表面粗糙度的影响均不显著。
Grinded zirconia ceramic ring inner surface with resin bonded diamond wheel,analysed the impact of grinding process parameters including the particle size of the grinding wheel,the linear velocity（vs）,the axial oscillation speed（fa） and the radial feed speed（fr） on roughness of the zirconia ring inner surface.Under the orthogonal experiment of grinding process parameters,obtained the regression equation of the surface roughness by regression analysis.Experimental results showed that the particle size of the diamond wheel was the most influential factor on the machined surface roughness,as the granularity size of wheel decreases,machined surface roughness was markedly decreased,while the changes of the line speed of the grinding wheel,the axial oscillation speed and radial feed rate had no significant influences on machined surface roughness.
