How does CNC machining work?

The control system of the CNC machining center can generally control the machine tool according to the digital program instructions to realize the automatic start-stop, reversing and speed change of the spindle, can automatically control the feed speed, direction and processing route, carry out processing, can select the tool and adjust it according to the tool size. Tool amount and walking track can complete various auxiliary actions required in processing.

CNC machining structure CNC lathe is also composed of spindle box, tool rest, feed transmission system, bed, hydraulic system, cooling system, lubrication system, etc., only the feed system of CNC lathe and the feed system of horizontal lathe There are essential differences in structure, the mechanical structure of a typical CNC lathe. The movement of the main shaft of the horizontal lathe is transmitted to the tool rest through the hanging wheel frame, the feed box and the slide box to realize the longitudinal and transverse feed movement. The CNC lathe uses a servo motor, which is transmitted to the slide plate and the tool holder through the ball screw to realize the z-direction (longitudinal) and set-direction (horizontal) feed movement. CNC lathe processing also has the functions of various threads, and the motion relationship between the rotation of the spindle and the movement of the tool holder is controlled by the CNC system.
