The strength of the workpiece material, the higher the hardness, the higher the cutting temperature generated, the faster tool wear

The strength of the workpiece material, the higher the hardness, the higher the cutting temperature generated, the faster tool wear, tool life is lower. Cutting carbon structural steel, carbon steel for tool life have a greater impact. The higher the carbon content, the proportion of cementite and pearlite greater the higher the hardness,  Polycrystalline diamond . Therefore, when the high-carbon steel cutting tool wear faster, lower durability; carbon steel cutting tool wear is relatively slow, durability is relatively high. Further processing of the material elongation of  Diamond blade  thermal conductivity, are to make the cutting temperature, reduced tool life. Tool material impact on tool life tool cutting part of the material affect tool life is a major factor in improving the cutting tool material, the use of high, the more wear and durability is also higher. Quality tool  grinding wheel  and cooling lubrication conditions on tool life of tool sharpening quality durability of the tool has a great influence. Such as cemented carbide cutting tools with silicon carbide grinding wheel, if no fine whetstone grinding, due to the small gap serrated blade, the higher front flank surface roughness and other reasons, the tool wear faster, low durability, and sometimes also easy chipping.
