Polycrystalline Diamond (PCD) Blanks:
PCD Blank (Polycrystalline Diamond Blank) is a high-performance super-hard material manufactured by sintering high-purity diamond powder with a high-strength metallic binder under extreme high temperature and high pressure (HPHT).
It combines diamond hardness with the toughness of a tungsten carbide substrate, offering exceptional wear resistance, ultra-high hardness, excellent thermal conductivity, and outstanding chemical stability.
These properties make PCD blanks an ideal material for manufacturing high-precision cutting, grinding, and drilling tools, especially for machining non-ferrous metals (aluminum, copper, magnesium alloys), non-metallic materials (stone, glass, ceramics, and composites such as CFRP/GFRP), as well as wood.
