[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the milling cutter mainly moves in rotation, and the movement of the workpiece and the milling cutter is the feed motion.

Once the inner cavity of the cooling liquid pipe 10 is blocked, the cooling liquid circulation speed slows down. At this time, within a certain period of time, the rotation speed of the rotating rod 15 slows down, thereby reducing the number of generated electrical signals. It can be determined that the inner cavity of the cooling liquid pipe 10 is blocked, so that the knife body 11 can achieve the cooling purpose.
