CNC machining What is the working principle of CNC machining?

Every machining technology has its own working principle. I want to know how a machining technology works. We only know how to understand it. CNC machining is also one of them. What is the working principle of CNC machining? ? Let me tell us about it.

The control system of CNC machining centers can generally control the automatic start and stop, reversing and speed change of the spindle according to the digital program instructions. It can automatically control the feed speed, direction and processing path, and perform processing. It can select tools and follow the tools. The scale adjusts the amount of knife and the walking trajectory, which can end various auxiliary actions required in the processing.

CNC machining structure CNC lathe is also composed of headstock, tool post, feed transmission system, bed, hydraulic system, cooling system, lubrication system, etc. It is only the feed system of the CNC lathe and the horizontal lathe. There are fundamental differences in the structure of the feed system, the mechanical structure of a typical CNC lathe. The movement of the main shaft of the horizontal lathe is transmitted to the tool post through the hanging wheel frame, the feed box, and the slide box, and the longitudinal and transverse feed motions are ended. The CNC lathe uses a servo motor, which is transmitted to the slide plate and the tool post via the ball screw, and ends the z-direction (longitudinal) and positioning (transverse) feed motion. Fine CNC machining also has various thread functions, and the movement connection between the spindle rotation and the movement of the tool post is controlled by the CNC system.
