  • GMD Wheel Grit
    GMD diamond wheel grit is manufactured from high purity raw material, and through strict sorting procedures....

  • The GMD series comprises nine grades for various applications ranging from metal bonded tools that require high toughness to electroplated tools that require excellent sharpness. It is widely applied to process stone, glass, ceramics, silicon, etc.
  • GRD Wheel Grit
    The GRD series diamond wheel grit comprises two types of crystals: mono-crystal and multi-crystal....

  • GRD10 and GRD20 are mono-crystal diamond. They have high sharpness and are well fit for resin bond, electroplated, and vitrified bond tools.

    GRD40 and GRD60 are multi-crystal diamonds. Every single particle is a polymer of many micro crystals and will micro-fracture into many sharp angles while working, giving the tools consistent sharpness. The multi-crystal grades GRD40 and GRD60 can significantly raise the tools’ grinding efficiency and reduce the energy consumption.

  • GMP Polishing Grit
    GMP is CR GEMS’ diamond micro powder manufactured from high quality raw material, through advanced size separation, strictest cleaning treatment and comprehensive quality control procedures....

  • Such as quantitative size control by Laser diffraction particle size analyzer, visual observing and imaging by scanning electron microscope.

    Its highly uniform size and outstanding purity could guarantee the fine surface finishing of the processed part, meanwhile makes it easy for directional grit planting technology.

    It has 4 types: GMP1, GMP2, GMP3 and GMP4 satisfying different applications: cutting, grinding, polishing and lapping, etc. In addition, various coatings are available for grit sizes over 10Um.

  • GMT Triangle Diamond
    The GMT series triangle diamond is characterized with octahedral crystal shape, with eight faces, sharp edges and sharp points....

  •  GMT diamond has high purity, very low magnetism; regular and uniform crystal shape as well as highly-centralized grain size. Therefore, it has relatively high SCT & impact toughness.

    GMT-5 triangle diamond’s consistent quality and excellent performance has been highly recognized by customers.Furthermore, a series of special treatments are done to

    GMT-5+, minimizing its static electricity and magnetism to close to zero, satisfying the strictest requirements of electronic industry, etc.
