机床的主运动(如刀具切削金属)、进给运动(刀具或工件的移动)及辅助运动(供给冷却润滑液,夹紧或松开工件、自动检测尺寸等)都通过电力或液压进行驱动(有时也可用人力驱动)。不少机床(包括加工螺纹)的主运动由一台电动机实现。该电动机也能同时实现主运动和进给运动之间的联系,包括工件转一转时,刀具能有精确的位移;还有部分机床的主运动及进给运动则分别采用不同的电动机提供动力。主传动系统包括电动机和用于向机床执
The main movement of the machine (such as cutting metal), feed movement (tool or workpiece movement) and auxiliary movement (supply of cooling fluid, clamping or release of workpieces, automatic detection of dimensions, etc.) are all driven by electricity or hydraulics Sometimes human-driven). Many machines (including the processing thread) of the main movement by a motor to achieve. The motor can also achieve the link between the main movement and the feed movement, including the precise displacement of the tool during the rotation of the workpiece. In addition, the main movement and feed movement of some machine tools are respectively powered by different motors . The main drive system includes a motor and is used to hold the machine
