Basic Requirements For Milling Cutter Cutting Some Materials

1. High hardness and wear resistance: At room temperature, the cutting part must have sufficient hardness to cut into the workpiece; with high wear resistance, the tool will not wear and prolong the service life.
2. Good heat resistance: The tool will generate a lot of heat during the cutting process, especially when the cutting speed is high, the temperature will be very high. Therefore, the tool material should have good heat resistance, which can still It can maintain a high hardness and have the ability to continue cutting. This property of high temperature hardness is also called thermal hardness or red hardness.
3. High strength and good toughness: During the cutting process, the tool must bear a large impact force, so the tool material must have high strength, otherwise it is easy to break and damage. Since the milling cutter will be subject to shock and vibration, the material of the milling cutter should also have good toughness so that it is not easy to chip and chip.
