The dull or damaged large diameter drill bits will affect the progress of the work, and due to the higher hardness, larger diameter, and larger sharpened area of large diameter drill bit, generally for manual sharpening that necessary worker to sharpen it with more experience, today, we are talking about how to sharpen large diameter drill bits with […]
Chemical Vapor Deposition (CVD) diamond coating has many excellent properties, such as high hardness, high thermal conductivity, low friction and low expansion coefficient. CVD diamond coated cutting tools are based on hard alloy materials and coated with CVD diamond film on the substrate of milling cutter, drill bit, blade and other tools to enhance cutting […]
The common cutting tool materials used in tool grinding include: high speed steel, powder metallurgy high speed steel, hard alloy, PCD, CBN, metal ceramics and other super hard materials. The high – speed steel tools have the sharp, the toughness good merit. Carbide cutting tools have high hardness but poor toughness. The density of carbide […]
