Problems solved by technology
[0002] At present, most of the existing milling cutters have multiple spiral chip flutes. The depth of the chip flutes is shallow, and the chip removal space of the chip flutes is small. During the processing, the waste chips are not easy to discharge, and the workpiece plate The cutting place is prone to burrs, which often cannot meet the processing requirements
