四轴球体研磨机球体研磨圆度误差均匀化效应的机理分析

从建立四轴球体研磨机弹簧加压球体研磨的力学模型入手,运用高点切削作用机制和误差均匀化效应,解释了球体圆度误差趋小化研磨机理。根据四研具对球面研磨的包络原理,提出了未包络研磨区是产生残存圆度误差的主要因素,并探讨了未包络研磨区、四研具初始压力误差、研具磨损不均匀性产生的原因和对研磨残存圆度误差的影响及解决措施。为进一步改善研磨工艺和提高球体研磨圆度提供了参考。

Mechanism Analysis of Homogenization Ball Lapping Roundness Error for the Four Shafts Ball lapping Machine

This paper introduces the ball lapping model of spring loading lap tools for the four shafts ball lapping machine and explains the small tendence mechanism of the ball roundness error using the effets of cutting high points and homogenization lapping error.It advances that the non lapping envelope region is a major fact of generating roundness errors,and inquires into the effects of ball roundness with non lapping envelope region,preliminary pressure error and lap tool wear.It gives the measures of solving these problems and provides basis for improving the ball lapping roundness.
