数控机床电主轴的检测与维护

Inspection and maintenance of CNC machine tool electric spindle

电主轴相较于传统机械主轴因为具有重量轻、转速高、摩擦和噪音小等特点正得到广泛的使用。电主轴是现代数控机床中最核心最精密的零部件,本文通过梳理电主轴经常出现的故障现象,维修维护过程中精度检测的项目和方法,总结出了有关电主轴精度检测,主轴的拆卸和安装,主轴的重新运行等方面的经验和方法。

Compared with traditional mechanical spindles,electric spindles are widely used due to their lightweight,high speed,low friction and noise.Electric spindle is the most core and precise component in modern CNC machine tools.This article summarizes relevant experiences and methods by analyzing the common faults of electric spindles and the items and methods of accuracy testing during repair and maintenance,such as precision testing of electric spindles,disassembly and installation of spindles,and rerun of spindles.
