数控车床试验台的改造

Transformation of Lathe Test Bench

主要针对华中系统的数控车综合实验设备,进行Z轴进给传动系统的改造,将其控制方式由开环控制改造为半闭环控制,从而提高该设备的精度。通过介绍改造的主要过程及其解决的主要问题,为实际进行数控机床改造提供一定的参考。

This article mainly aims at the HNC system lathe test bench,transforating Z axis feed drive system,its control mode from the open loop control transformation is half closed loop control,so as to improve the accuracy of the device.Through the introduction of the reform of the main process and solve the main problems and practical for CNC machine tools provide certain reference.
