翻译进给系统作为数控机床的关键部件其定位精度直接影响机床整机的加工精度影响精密数控机床定位精度的主要原因除热误差外还包含在加工装配过程中引入的几何误差。本文以T55精密数控车床为对象对其进给系统的热误差和几何误差进行研究最终实现定位精度的提高。

As a critical component of CNC machine tools, the feed system's positioning accuracy directly affects the machining accuracy of the entire machine tool. The main factors affecting the positioning accuracy of precision CNC machine tools, in addition to thermal errors, also include geometric errors introduced during the manufacturing and assembly process. This article focuses on the T55 precision CNC lathe and studies the thermal and geometric errors of its feed system to ultimately achieve an improvement in positioning accuracy
