[0002] The turning and milling compound machine tool is the fastest growing and most widely used CNC equipment among compound processing machine tools. Turning and milling compound processing is to realize two different processing technologies, turning and milling, on a single machine tool. The purpose of compounding is to make a single machine tool multifunctional, to complete multiple tasks in one clamping, and to improve processing efficiency and processing accuracy.

[0003] The machine tool is also equipped with a tool magazine with the function of automatically replacing milling cutters. The milling cutter is used in conjunction with the tool holder, and the milling cutter is connected to the mechanical spindle on the machine tool through the tool holder, which is conducive to lightweight and high-speed tool change. The common HSK tool holder is a new type of high-speed short-taper tool holder. Its interface adopts the method of simultaneous positioning of the cone surface and the end surface. The tool holder is hollow, the cone length is short, and the taper is 1 / 10.
