They are flexible, high-performance automated machine tools, represent the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] At present, CNC machine tools are generally equipped with a single spindle for processing parts, so the processing efficiency is low. In order to improve the processing efficiency, a CNC machine tool is equipped with multiple spindles to process parts synchronously. However, the existing CNC machine tool multi-spindle can only process the same part according to a single program, and it is impossible to control different parts processing operations on a CNC machine tool, which makes the applicability of CNC machine tools poor. This problem needs to be solved urgently. Utility Model Content
