在数控强力切削进给伺服系统中，机械传动系统对电气调速系统具有扭矩反馈作用，容易形成机械谐振。

In CNC heavy cutting servo system, mechanical drive system has a torture feedback on electrical speed-adjustment system, thus it's possible to generate the mechanical resonance.

伺服进给系统的综合拉压刚度由伺服驱动系统刚度和机械传动系统刚度组成，其各自又受多项因素的影响。

Servo feed system comprehensive pull-pressing rigidity is made up of the rigidity of servo drive system and the rigidity of mechanical transmission system, and each is affected by multiple factors.

本传动系统由交流伺服电机、滚珠丝杠及直线导轨等组成。

The drive system consists of AC servomotor, ball screw and rectilinear orbit etc.
