在外圆磨床或端面外圆磨床上磨出内凹端面的几种情况及原因浅析

摘要

零件磨削后的端面有时会有凹凸方面的要求，要求允许适量内凹而不允许内凸的情况较多，而加工中经常出现的是内凸。有必要对磨削端面如何产生内凹进行研究。为此，根据经验，对在外圆磨床或端面外圆磨床上磨端面会出现内凹的几种情况进行介绍并简单分析其原因。%Sometimes inner concave or inner protuberance is re- quired after head face is grinded, generally modesf inner concave is required and inner protuberance is not allowed, but inner protuberance is produced often. It is necessary to research how to produce inner concave of grind head face. And so as a matter of experience several instances is presented about that head face is grinded into inner concave by cylinder grinder or head face ＆ cylinder grinder, the reason is also analyzed.
