[0003] When a general CNC machining device is working, the workpiece is fixed on the operating platform. The positioning mechanism needs to perform initial positioning multiple times before the control box processes the workpiece. The adjustment work takes a lot of time, which reduces work efficiency. When performing multi-directional processing on irregular workpieces, the general positioning mechanism is prone to positioning deviations, resulting in the cutting depth or weld height of the workpiece being inconsistent with the predetermined depth or height, reducing the quality and appearance of the product, increasing the unqualified rate of the product, and causing an increase in production costs.
