The booster-type unclamping cylinder is adopted for the spindle head, so that it has the advantages of compact structure and high-speed automatic tool change. It is mainly applied to the full-automatic equipment, and can realize to store a certain quantity of cutter and automatic tool changer completing the automatic exchange function of cutter by matching the various tool magazines. The processing efficiency of the numerical control machine tool is further improved,and one clamping isrealized, namely, many processes can be completed; and it is assembled into the CNC milling machine or component of the spindle system in the machining center. 

缩短非切削时间，提高生产效率，可使非切削时间减少到 20%-30%；减少人工换刀频率的劳动重复性。

The non-cutting time is shortened, the production efficiency is improved, and the non-cutting time can be reduced to 20%-30%; and the labor repeatability of the manual tool change frequency is reduced.

工序集中，扩大数控机床工艺范围，减少占地面积。

The process is concentrated, so as to expand the process range of the CNC numerical control machine tool, reduce the floor space.

提高加工精度，刀具重复定位精度高，安全可靠的特性。

Improve the machining precision; and moreover, it has characteristics of high repeated positioning accuracy of the cutter and safety and reliability.
