Working principle of CNC machining


Working principle of CNC machining

Every processing technology has its own working principle. If we want to know what the working principle of a processing technology is, we only know that CNC processing is one of them. What is the working principle of CNC processing?

The control system of CNC machining center can generally control the machine tool to stop, change direction and speed automatically according to the digital program instruction. It can automatically control the feed speed, direction and processing path to process. It can select the cutting tool and adjust the cutting amount and walking track according to the cutting tool size, and can end all kinds of auxiliary actions required in the processing.

CNC machining structure CNC lathe is also composed of headstock, turret, feed transmission system, bed, hydraulic system, cooling system, lubrication system and other parts, but CNC lathe feed system and horizontal lathe feed system in the structure is essentially different, typical CNC lathe mechanical structure composition diagram. The movement of the horizontal lathe spindle is transmitted to the tool rest through the change gear frame, feed box and slide box to end the longitudinal and transverse feed movement. The CNC lathe is to select servo motor, through the ball screw to slide plate and turret, end Z direction (longitudinal) and set direction (transverse) feed movement. Fine CNC machining also has the function of various threads. The movement between spindle rotation and tool rest movement is controlled by CNC system.
