Polycrystalline Diamond (PCD)

SinoDiam Polycrystalline Diamond (PCD) Materials are advanced synthetic diamond cutting materials developed for precision machining of non-ferrous metals, composites, engineered wood and other abrasive workpieces.

PCD is manufactured by sintering synthetic diamond particles under high-pressure, high-temperature conditions to form a polycrystalline structure with excellent hardness and wear resistance. These characteristics make PCD suitable for cutting tools requiring consistent machining performance and extended service life.

Our PCD product range includes SDPD series materials, such as SDPD032-A and SDPD032-B, offering different combinations of abrasion resistance, impact toughness and cutting performance for industrial tool manufacturing.

SinoDiam PCD materials are used in machining aluminum and silicon-aluminum alloys, copper alloys, carbon fiber composites, chipboard, laminate flooring, plastics and selected abrasive non-metallic materials. Typical applications include precision cutting inserts, woodworking tools, milling cutters and specialized machining components.

PCD material selection depends on workpiece properties, diamond grain structure, tool geometry, cutting speed, machining conditions and the required balance between wear resistance, surface finish and cutting-edge durability.

For hardened steels, cast iron and other ferrous machining applications, Polycrystalline Cubic Boron Nitride (PCBN) materials are generally more suitable and should be evaluated separately.
