[0002] A CNC milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth intermittently cuts off the excess of the workpiece in turn. The milling cutter is mainly used for processing steps, grooves, forming surfaces and cutting off workpieces. According to the structure, the milling cutter is divided into integral type, integral welded tooth type, inlaid tooth type and indexable type. When installing the CNC machine tool milling cutter, first install the collet into the clamping handle nut of the CNC machine tool, and then the tool rod at the tail of the milling cutter can be inserted into the collet in the middle of the nut, and then the nut can be screwed and installed on the clamping handle to install the milling cutter.

[0003] At present, when the integral milling cutter of a CNC machine tool is installed on a special tool holder, it is usually necessary to remove the clamping tool holder nut of the CNC machine tool, then pull out the tool rod of the milling cutter in the collet, then reinsert the tool rod of the new milling cutter into the collet, and screw the tool holder nut back to the clamping tool holder. The milling cutter installed in this way is inconvenient to disassemble and install, which affects the tool changing efficiency of the CNC machine tool. For this reason, we propose a milling cutter for CNC machine tools that is easy to disassemble and install. Utility Model Content
