Metal Bond Diamond

The MBD series encompasses M100, M200, M500,and M700. This graded series of products extends from M100, which is a relatively low-strength crystalline abrasive to MBD700.

MBD series products are widely used for drilling, grinding, and polishing applications in the optical glass, stone processing,

machinery processing electronics industries, etc.

    Description

    BRD-M100
    Characteristic: Relatively complete shape of medium transparency. Good self-
    sharpening,medium impact toughness, ideal balance between tool life and surface finish requirements.
    Application: Cut-off wheels for glass, honing cylinder, tungsten carbide, dental burrs, single crystal and polysilicon, plastic and other non-metallic brittle materials.
    Available size: 60/70 - 500/600

    BRD-M200
    Characteristic: Uniformed shape with high impact toughness and thermal resistance.
    Application: Decorative grooving of crystal & glass PD grinding of crystal, core drilling of glass. Middle stage grinding of crystal & granite OD grinding of silicon nitride.
    Available size: 60/70 - 500/600

    BRD-M500
    Characteristic: Well-defined cubo-octahedral, minimized impurity, superior thermal impact.
    Application: Suitable for processing non-metallic materials such as ruby, sapphire,
    optical glass, sawing of granite & ceramic tiles, grinding of ferrite motor core, electronics industry and etc.
    Available size: 60/70 - 400/500

    BRD-M700
    Characteristic: Perfect cubo-octahedral lowest impurity and super transparency,
    outstanding strength and thermal stability.
