数控机床用高速电主轴技术的现状与发展趋势

The state and development about the high-frequency motor spindles for NC machine tools

本文在总结数控机床用高速电主轴特点的基础上,介绍了国内外电主轴技术的现状和发展趋势,分析了我国电主轴技术与国外先进水平之间的差距,并提出了发展我国数控机床用电主轴技术的相应对策。

Based on the summary on the features of high-speed motor spindles equipped on CNC machine tools, this article introduces the-state-of-the-art and developing trend of the motor spindles both at home and abroad. An analysis is made on the space between the technology in China and the advanced level at abroad. It suggests a related policy and solution for deve- loping the motor spindle technology for machine tools in China.
