CNC lathe is one of the most widely used CNC machine tools. It mainly realizes turning and drilling of metal parts.

The driving device of a CNC machine tool includes a spindle drive unit, a feed unit, a spindle motor, and a feed motor. It realizes spindle and feed drive through electric or servo system under the control of numerical control device.

As an industrial master machine, CNC machine have extremely high requirements for the control performance of frequency drives.
