[0002] CNC milling machine is also called CNC milling machine. In English, it means a milling machine controlled by electronic digital signals. 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 also somewhat similar. CNC milling machine can be divided into two categories: without tool magazine and with tool magazine. Among them, CNC milling machine with tool magazine is also called machining center.

[0003] Existing CNC milling machines generally process workpieces through milling cutters. The temperature of the milling cutter will gradually increase after working for a long time. It is impossible to reduce the temperature of the milling cutter surface and protect the milling cutter, which will cause the milling cutter to overheat and break, thereby reducing the working efficiency of the CNC milling machine. At the same time, when processing the workpiece, the debris generated is easy to splash, which can easily cause harm to the staff and reduce the safety of the CNC milling machine during operation.

[0004] According to a CNC milling machine provided by publication number: CN211361311U, the utility model includes a bed and a fixing unit; bed: a spindle is provided on the inner upper surface of the bed, a fixing shaft is provided at the bottom end of the spindle, and a table is provided at the bottom of the inner side surface of the bed; the fixing unit: the fixing unit includes a fixing block, a screw, a connecting rod, a fixing ring, a threaded hole, a mounting rod and a mounting plate, a blind hole is opened on the bottom surface of the fixing block, the fixing block is arranged at the bottom end of the fixing shaft, the screw passes through the side surface of the fixing block and extends into the blind hole, one end of the connecting rod is arranged on the bottom surface of the fixing block, the other end of the connecting rod is fixedly connected to the fixing ring, a threaded hole is opened on the outer side of the mounting rod, the screw is threadedly connected to the mounting rod through the threaded hole, and the mounting plate is arranged at the bottom end of the mounting rod. The turning and milling positioning device of the CNC milling machine and the CNC milling machine can perform milling and turning on the same CNC milling machine, and also has a positioning device common to turning and milling, which effectively improves the production efficiency.

[0005] According to the CNC milling machine introduced above, the temperature of the milling cutter will gradually increase after working for a long time.
