PCD (polycrystalline diamond) diamond blades are cutting tools made from a combination of polycrystalline diamond and a metallic substrate. They have high hardness and wear resistance, so they are often used to machine hard materials such as hard alloys、silicon carbide, and composite materials PCD diamond blades are commonly used in automated machinings, such as on CNC centers and lathes. They are also widely used in the automotive, aviation, chemical, and other industrial processing fields.
