本文介绍了应用可编程序控制器(PC)控制的液压多刀半自动车床,实现了多种功能的自动控制,由于考虑到生产实际的加工需要,对其进行了改造,取代了以继电器控制为主的传统控制方法.除保留机床原有功能外,还增设了自动控制功能,如自动加工,循环加工及循环加工次数的设定等. This paper introduces a hydraulic multi-knife semi-automatic lathe controlled by a programmable logic controller (PLC), which realizes the automatic control of various functions. Due to the actual processing needs of the production, it has been transformed to replace the control system with relay control The main traditional control methods, in addition to preserving the original machine functions, but also the addition of automatic control functions, such as automatic processing, recycling and processing cycles set the number of times.
