Who have the main power source of the DC motor speed, in most CNC machine tools in the main rotation gradually replaced by the AC variable speed spindle motor. ????Variable speed main drive system and process according to the scope of the different species, divided into two categories, one can of high-speed CNC machine tools designed, one is universal CNC machine tools. The main two types of machine tool drive system are very different, the transmission program is also very different. ????This paper analyzes the above two types of machine tools, design and related parameters are given on the classification series stepless speed change mechanism of the main drive system design approach, in theory, be analyzed and discussed. Finally, a design example. Key words：Professionals can turn high-speed CNC machine tools、 universal CNC machine tools、control 2 高速专能化数控机床主传动无级调速 对要求主轴转速高，变速范围和恒功率区变速范围都较小的数控磨床、高精密数
