Polish grooves and carvers to make

Second, master the correct sharpening Angle

When grinding grooves and carving tools, the grasp of Angle is very important. If the Angle is too small, the edge surface will become too sharp, easy to break or damage; If the Angle is too large, it will lead to passivation of the edge surface and is inconvenient to use. Therefore, the correct sharpening Angle should be selected according to the specific type and use of the groove carving tool.

First, initial grinding is done with a coarser grinding stone, and then gradually turn to a finer grinding stone until the polishing is complete. In this process, the sharpness of the cutting edge should be constantly checked to ensure that the desired effect is achieved.

Fourth, the correct cutting edge oil protection

After finishing the grinding of the groove carving knife, it is necessary to pay attention to the protection of the cutting edge. Usually, the cutting edge is coated with a layer of oil film, which can effectively protect the cutting edge from air oxidation and other factors, and also extend the service life of the milling groove carving tool.

5. Pay attention to safety issues

When grinding grooves and carving tools, we must pay attention to safety issues. It is recommended to wear appropriate gloves and goggles when sanding to avoid injury from metal puncture wounds and grinding powder splashing. In addition, you need to choose the right position and posture to keep yourself and those around you safe.
