Structure and working process description of CNC lathe: The composition of CNC machine tools generally consists of input/output devices, CNC device (CNC), servo unit, drive device (or actuator), programmable controller (PLC) and electrical control device, auxiliary device, machine body and measuring device. Dongguan Wanjun specializes in large-scale precision parts processing. A CNC lathe is also composed of parts such as the spindle box, tool holder, feed transmission system, bed, China Material Recycling Network, hydraulic system, cooling system, lubrication system, etc. However, there is an essential difference in structure between the feed system of a CNC lathe and that of a horizontal lathe. In a horizontal lathe, the motion of the spindle passes through the gear rack, feed box, and saddle box to the tool holder, realizing longitudinal and transverse feed motions. In contrast, a CNC lathe uses a servo motor to transmit motion via a ball screw to the slide and tool holder, thereby achieving z-axis (longitudinal) and x-axis (transverse) feed motions. CNC lathes also have the function of machining various types of threads. The motion relationship between the spindle rotation and the tool holder movement is controlled by the CNC system. Inside the spindle box of a CNC lathe, there is a pulse encoder installed. The motion of the spindle is transmitted accurately to the pulse encoder via a synchronous toothed belt. When the spindle rotates, the pulse encoder sends detection pulse signals to the CNC system, ensuring that the rotation of the spindle motor and the cutting feed of the tool holder maintain the motion relationship required for thread processing. This means that during thread processing, for each revolution of the spindle, the tool holder moves longitudinally by one pitch of the workpiece.
