[0002] A CNC lathe is a mechanical device that uses programming control to complete part processing in the form of digital instructions. It is also called a machine tool or lathe. In the processing of specific transformer parts, the demand is large, and the processing efficiency of ordinary lathes is relatively low, and the labor intensity is high. During processing, the product end face is cut and formed at the same time, and then holes are drilled. After the holes are drilled, they are cut again, and the cutting and drilling actions are repeated continuously. The existing automatic CNC machine tools basically meet the needs, but there are still certain shortcomings. The existing CNC machine tools need to stop the spindle for feeding, and then feed, and the feeding time is long.
