Due to these tools, the cutter head has a small size, low strength, and is difficult to manufacture. The geometric angle of the artificial sharpening tool is difficult to ensure, and the blade is seriously damaged during cutting, which increases the consumption of the cutter. For this reason, domestic and foreign manufacturers are actively researching and developing the cutting of the cemented carbide machine.
