Note the high hardness of stone carving tools and wear resistance
发布时间:2016-12-20
Hardness is the basic characteristics of the stone tool material should have, cutting tools from the workpiece material, the hardness must be greater than the hardness of the workpiece material, tool material hardness is generally more than 60HRC, wear resistance is the ability of materials to resist wear, the general situation , The higher the hardness of the tool material, the better the wear resistance, the finer the grain of the material, the more uniform the distribution, the higher the wear resistance.
