[0002] At present, the transmission principle of the existing large and medium-sized CNC flat rotary table is usually as follows: through the numerical control program, the expansion and contraction of the boring bar is converted into the horizontal displacement of the tool through the precision mechanism in the flat rotary table; the axial displacement of the tool is passed through the movement or working of the ram The worm is driven by the motor to provide the feeding power of the slide; the gear is driven by the milling shaft to provide the rotating power of the rotating body; the planetary wheel differential mechanism eliminates the influence of the rotating motion on the feed of the slide to realize the slide. Normal feed; when processing the workpiece, the workpiece is often used to pass automatically, the tool does not move, it is easy to cause the workpiece to shift, and the accuracy is reduced

The invention discloses an NC (numerical control) facing head. The facing head comprises: a main shaft, wherein a bearing and a positioning sleeve are arranged on the surface of the main shaft, and the main shaft is connected with a main shaft motor; a transition pad, arranged on the left side of the main shaft; a cutter head body, arranged on the left side of the transition pad and fixedly connected with the main shaft, wherein a main shaft motor drives the main shaft to rotate, and the main shaft transmits the rotating motion to the cutter head body through the transition pad. Under the condition that a workpiece is fixed, the cutter head body rotates and conducts turning machining on the workpiece, stability is good, the structure is compact, machining precision is high, and machining procedures are simple and rapid.
