Diamond grinding wheels are made of diamond powder, and there have the bond types of metal, resin, vitrified and electroplated bond. They are round bonded abrasive tools with central through-hole. They are mainly composed of the diamond layer, transition layer, and matrix.
According to the types of bond, diamond grinding wheels are divided into resin bond grinding wheel, metal bond grinding wheel, vitrified bond grinding wheel, electroplated bond grinding wheel.
Features and applications of resin bond diamond grinding wheels:
Good self -sharpening, less blocking
The wheel has a certain elasticity and is good surface finish, is mainly used for finishing, semi-finishing, sharpening and polishing
Easy to make diamond grinding wheels with complicated surface
Applications: Mainly used for semi-finish and finish grinding of tungsten carbide tools, steel-bonded cemented carbide, optical glass, and some non-metallic materials.
Features and applications of metal bond diamond grinding wheels:
Good rigidity and high strength.
Good wear resistance and long service life
Good shape retention and can bear a heavy load
Applications: Mainly used in rough and finish grinding glass, optical lens glass, ceramics, semiconductor materials, superhard materials, and other non-metallic materials, and few used for rough grinding and molding grinding cemented carbide.
Features and applications of vitrified bond diamond grinding wheels:
Vitrified bond has high strength and good heat resistance
Good sharpness and high grinding efficiency
Lower grinding heat, anti-clogging, small thermal expansion, and easy control machining accuracy
Easy dressing
Applications: Usually used for rough grinding, semi-fine grinding, molding grinding with large contact areas, sintered superhard abrasive grinding, such as carbide tools, PDC, PCD and PCBN tools.
Features and applications of electroplated bond diamond grinding wheels:
Electroplated bond has high strength, thin abrasive layer, high abrasive density, sharp cutting, high grinding efficiency, good economy, no dressing.
Applications: Mainly used for making complex shape diamond grinding tools, small diamond mounted points, cutting blades and high speed grinding.
