PCD tools are mainly used in cutting and processing of non-ferrous metals, hard alloys, ceramics, non-metallic materials (plastics, hard rubber, carbon rods, wood, cement products, etc.), composite materials, etc., gradually replacing hard alloy tools. Due to the presence of residual bonding metal and graphite between diamond particles, the bonding metal distributed in a cohesive or vein like state can reduce the wear resistance and lifespan of the cutting tool. In addition, there is a residual amount of solvent metal, which comes into direct contact with the diamond surface. Diamond coated tools can be applied to high-speed machining because, in addition to the excellent mechanical properties of diamond coated tools, the diamond coating process can prepare milling cutters of any complex shape for high-speed machining of aluminum titanium alloy aviation materials and difficult to machine non-metallic materials such as graphite electrodes

The advantages of diamond PCD tools are:

1 diamond PCD tools have large elastic modulus,

2 cutting edge blunt radius value can be ground very small, not easy to break,

3 can maintain the cutting edge sharpness for a long time: diamond tools have small coefficient of thermal expansion and small thermal deformation
