[0002] The CNC machining platform is mainly used for machining some precision parts and can realize multi-axis linkage machining. In traditional CNC machining, adding a four-axis tailstock can perform rotary machining in a single direction of the Y-axis. After machining complex workpieces, the workpiece needs to be unloaded for secondary clamping, and the machining coordinate system needs to be re-searched to complete the machining of the remaining features by rotating the X-axis, thus affecting the machining efficiency of the CNC machining platform.

[0003] In view of the above problems, Chinese Patent CN 220993525 U discloses a multi-axis platform for CNC machining, including a bottom plate (1). The top of the bottom plate (1) is fixedly connected with a mounting plate (2). The top of the mounting plate (2) is fixedly connected with a speed reducer (3). The top of the mounting plate (2) is fixedly connected with a support seat (4). The top of the support seat (4) and the output end of the speed reducer (3) are both provided with a CNC four-axis rotary table (5). A CNC 4-axis bridge plate (6) is fixedly connected between the two CNC four-axis rotary tables (5). The top of the CNC 4-axis bridge plate (6) is provided with a plurality of fixing screw holes (10). A base screw (13) is inserted into the fixing screw holes (10). The top of the CNC 4-axis bridge plate (6) is provided with a 4.5-axis fixing base (11).
