Editor’s Note
This article explores the unique properties of Polycrystalline Diamond (PCD), highlighting its superior cutting performance and self-sharpening ability, which make it exceptionally well-suited for high-precision machining of ultra-hard materials.
Polycrystalline Diamond (PCD) is structurally similar to natural carbonado. Compared to single-crystal diamond, it features a greater number of cutting edges, higher removal rates, and superior self-sharpening properties. Its structure allows worn crystal grains to detach, continuously exposing new sharp edges, making it an ideal material for processing ultra-hard materials that require extremely high precision.
Minimizes damage to ultra-hard materials.
Used for processing insulators and functional materials.

Polycrystalline diamond micron powder is a powder with a polycrystalline structure composed of fine diamond particles, typically ranging in size from sub-micron to several microns. It is manufactured through special methods such as explosive synthesis or high-pressure high-temperature (HPHT) processes. Unlike single-crystal diamond, it has a structure where numerous tiny crystal grains are aggregated. This structure provides “self-sharpening,” where new sharp edges constantly appear during grinding or processing, delivering stable processing performance.
Characteristics of polycrystalline diamond powder include high hardness, wear resistance, thermal stability, and the ability to minimize damage to the processed surface. Even as fracturing progresses during use, crystals within the particles are successively exposed, allowing sustained high grinding force. Additionally, compared to single-crystal diamond powder, it offers the advantage of fewer scratches during processing and a smoother surface finish.
