[0002] CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machine is divided into two categories: without tool magazine and with tool magazine. Among them, CNC milling machine with tool magazine is also called machining center. CNC milling machine usually clamps and positions the workpiece manually during processing to avoid the workpiece from shifting during processing. There are the following shortcomings when using it:

[0003] 1. Manually replacing workpieces takes a certain amount of time, and during this period the equipment is always in a stopped state, resulting in low processing efficiency.

[0004] For this purpose, we propose a CNC milling machine for precision machining. Utility Model Content
