Quick Information

  • Brand Name: EGrind
  • Place of Origin: China

1)  Properties

  • Detonation-synthesized polycrystalline diamond micro-powder

  • The structure resembles the rare natural polycrystalline black diamond, metallic-grey, superior toughness, self-sharpening.

  • The lapping and polishing efficiency of the detonation-synthesized polycrystalline diamond micro-powder is 2 to 4 times better compared with that of the mono-crystalline diamond that is naturally occurred or synthesized via the static pressure method, Silicon Nitride, Corundum, and other abrasive materials.

  • polycrystalline diamond micro-powder allows the manufacturing of the smoothest surface possible:

    a.  When using polycrystalline diamond micro-powder of size 2-4micron to the polishing surface, Ra(roughness)<1.6nm
    b.  When using polycrystalline diamond micro-powder of size 0-0.5micron to the polishing surface, Ra(roughness)<1.3-1.4nm
    c.  When using polycrystalline diamond micro-powder of size 0-0.125micron to the polishing surface, Ra(roughness)<0.1nm

  • polycrystalline diamond can maintain its dull mono-crystalline structure by releasing the outer layer, hence will produce the most scratch free surface possible.

  • When applied to the surface of a workpiece (for example, the inner surface of a cylinder in an engine) via chemical plating method, the wearability of the surface is superior to that of a surface treated with any other materials.

  • Via after-sinter technique, polycrystalline diamond micro-powder can be turned into polycrystalline diamond particles of a large size that are highly valuable in a variety of industries.

    2) Application

  • Lapping and polishing a variety of surfaces that require superior smoothness.

  • Improving the wearability of a mechanical component

  • Via after-sinter technique can be applied in a variety of industries.

  • Can be made into liquid abrasives, gel abrasives, and many other types of abrasive tools that are capable of ultra-fine lapping and polishing tasks.

    Polycrystalline diamond micron powder can be used for below industries: 

  • Computer industry: Read/Write head lapping, rigid disk media texturing

  • Gem polishing

  • Semi-Conductor, electronic ceramic, optical instruments

  • Used as anti-wearing media in special rubber and plastics

  • Chemistry catalyst, Biomedicine
