Commonly used planer knife materials

The properties that tool materials should have. The cutting part of the planer works under high temperature and severe friction. Therefore, the tool material must have the following properties: (1) High hardness (cold hardness). The hardness of the tool material must be higher than that of the material being processed. (2) High wear resistance makes the tool less likely to wear out during long-term cutting. (3) High heat resistance means that the tool can still maintain good cutting performance at high temperatures. In addition to having oil-free cutting performance, the tool material should also have good industrial and economic properties as much as possible.

Types and uses of planer materials The materials of the cutting tools mainly include tool steel, high-speed steel, cemented carbide, ceramics, etc. At present, the commonly used planer materials are high-speed steel and cemented carbide.
