Grinding wheel machine
One of the uses of the grinding wheel machine is the grinding of the cutting tool, in the process of cutting metal, the material of cutting tools. Under the pressure of larger, higher temperature and intense friction, the tool wear. The length of service life and the productivity of cutting tools depend on whether or not the cutting performance of the tool material. In addition, the process of cutting tool cutting part of the material has a significant impact on the quality of the cutting tools and cutting tools. Therefore, tool material G1 must have the following performance:
(1) the hardness of the high hardness cutting part of the cutting tool material is higher than the hardness of the workpiece material, at room temperature, the cutting tool is hard.
Degrees should be higher than 60HRC above.
(2) high wear resistance is usually determined by hardness. The higher the hardness of the material, the better the wear resistance. Wear resistance
The more the better the carbide particles, the finer the grain, the more uniform distribution, the better wear resistance.
(3) sufficient strength and toughness of the cutting part of the cutting tool material is subjected to various stresses and shocks. In order to prevent cutting tool edge and fracture, we must have sufficient strength and toughness. The flexural strength and impact toughness of the materials are usually expressed as o
(4) high heat resistance is defined as the performance of the material at high temperature when the cutting part of the material is kept at room temperature, which can be expressed by hot or high temperature hardness.
(5) a good technological performance for manufacturing, cutting tools cutting part of the material should have good forging, welding, heat treatment and grinding performance. At the same time, it should be as far as possible to meet the requirements of resource rich and low cost. So, the wear of the tool is repaired by the grinding of the grinding wheel. West Lake sand turbine is the preferred brand!
