In high-speed cutting, the machining accuracy, cutting life and productivity are influenced by the high rotational speedofspindle.
高速切削时主轴转速很高，加工精度、刀具寿命和生产率受到影响。

Two-step drive device make the force-enduring reasonable, and the frequency converter control the motor, it is easier to adjust the speedofspindle.
二级传动结构，使受力更合理，变频控制电机，可以方便调整所需转速。

This function can make numerical control system according to the point in the X coordinates, as the diameter of the workpiece calculated value spindlespeed, and the cutting speed to be constant.
