摘要
电主轴的性能尤其是动态性能直接影响着主轴运转的稳定性及高速加工的加工精度和生产效率,也决定着高速数控机床的整体发展水平。通过分析数控机床高速电主轴动态性能的主要影响因素,搭建了电主轴动态性能测试试验平台,完成了电主轴在1 000-15 000 rpm转速范围内的振动信号采集与处理,实现了电主轴的动态性能测试与分析,并据此提出了提高电主轴动态性能的有效措施。
By analyzing the main factors affecting dynamic performance of CNC machine tool of high speed motorized spindle,the experimental platform of motorized spindle dynamic performance test was built. Vibration signal acquisition and processing of motorized spindle under different speed was completed. Test and analysis of dynamic performance motorized spindle was implemented. On this basis,the effective measures to improve the dynamic performance of motorized spindle were proposed.
