Modern furniture and building materials use a wide range of materials, from natural wood to cementitious building materials. Superalloys, ultrafine particle tungsten carbides, cermets, special thermal-sprayed metals, and "SUNPAX", are used for cutting tools to process such materials. Diamond wheels are used to shape and grind those tools, and a wide range of grinding capabilities are required. Asahi Diamond offers the most suitable bond system for each type of material, from chip saws to planer blades.

In the machining of precision parts and mechanical parts made of ceramics and other materials, the technology of uniformly dispersing abrasive grains in the abrasive grain layer has made it possible to improve sharpness while maintaining a long service life, compared to conventional metal tools.
In addition, the ultra-thin abrasive grain layer reduces machining load and chipping in the machining of hard and brittle materials and other special materials, thereby improving machining efficiency and demonstrating its superiority over other tools.

Bright Star is a superabrasive wheel with a special bond structure that has a high elasticity not found in conventional resin bonds, and is effective for processing that requires luster. BRS2 Bond is a hard type that is effective for processes that require a certain amount of material to be removed, and is compatible with both lapping and grinding. BRS5 bond is a soft type and is effective for polishing processes such as lapping and polishing.

NEO STAR wheels are bonded with polyimide resin, which has excellent heat resistance, tensile strength, and elasticity. It can be used for grinding that requires long-time shape retention, heavy-duty grinding, creep-feed grinding, efficient grinding of high-hardness steel (HRC67 higher), and grinding of relatively low-hardness steel (HRC40-50 ) that requires long life.

Vitrified grinding wheel using general abrasive grains. A wide variety of wheel configurations from soft to hard are possible, and they are effective as dressing materials for metal tools.

Vitrified bonded grinding wheel using cubic boron nitride abrasive grains. They are highly evaluated for grinding ultra-precision parts with super-finished bearing raceway surfaces. In addition to standard CBN wheels. we offer a broad lineup of CBD wheels, which emphasize sharpness, and DBN wheels, which emphasize surface finish accuracy, allowing us to design wheels that meet your needs.
