数控机床有挡块返回参考点方式是数控机床上广泛采用的一种回零方式,同时,有挡块返回参考点在数控机床故障中发生的概率也比较大,快速而有效的排除此类故障是保证企业顺利生产的必然要求。本文重点介绍有挡块回参考点的工作原理、动作方式、参数设置、PMC控制及常见故障分析与排除方法,以期为数控机床此类故障的排除提供可借鉴的方法。
CNC machine tools have a stop to return to the reference point is a widely used CNC machine tools back to zero at the same time, there is a block back to the reference point in CNC machine tool failure probability is relatively large, quickly and effectively rule out such failures Is to ensure the smooth production of enterprises a necessary requirement. This article focuses on the working principle, action mode, parameter setting, PMC control and common fault analysis and elimination methods of the reference point with a stop back to provide a reference for the exclusion of such failures of CNC machine tools.
