摘要
采用在线电解(ELID)磨削技术对轴承套圈进行精密磨削实验,研究了在相同的磨削时间内不同导电率的磨削液对工件表面粗糙度的影响规律,以及同一导电率的磨削液随着磨削时间变化对工件表面粗糙度的影响规律,利用正交试验法对轴承套圈的工艺参数进行优化设计,试验结果表明,当磨削液导电率在合理的范围内时,磨削液的导电率越大,工件的表面粗糙度就越小,对于同一导电率的磨削液,随着磨削时间的增加,工件表面粗糙度呈现小幅度的增大,利用正交试验优化得出的方案提高了轴承套圈的加工精度。
Carries on online electrolysis （ELID） grinding technology for bearing ring precision grinding experiment,studies at the same time the effects of different conductivity of grinding fluid on the workpiece surface roughness,and effects of the same conductivity of grinding liquid with the grinding time change on the workpiece surface roughness are studied,using the orthogonal experiment to optimize and design the process parameters of bearing ring,the results showed that when the conductivity of grinding fluid in a reasonable range,the greater the conductivity of the grinding fluid,the smaller the surface roughness of the workpiece,for the same conductivity of grinding fluid,with the increase of grinding time,the surface roughness of workpiece present a modest increase,the optimize scheme from orthogonal experiment can improve the machining precision of bearing ring.
