[0002] A milling cutter is a multi-tooth tool used to process planes, steps, grooves, formed surfaces and cut off workpieces on a milling machine. Its working principle is that each tooth cuts off the excess of the workpiece intermittently in sequence. The milling cutter is an indispensable tool in modern mechanical finishing. Correct selection and use of the milling cutter can greatly improve processing efficiency and quality. When choosing a milling cutter, you should choose it according to specific processing requirements and conditions.

[0003] During the use of existing milling cutters, it is necessary to clean the chips generated by the milling cutter. Generally, an air gun is used to move with the cutter to blow away the chips. However, the air gun is large in size and needs to be a certain distance away from the cutter, so it cannot clean the chips attached to the milling cutter. The chips attached to the cutter body will affect the use of the milling cutter.
