Diamond metal wheels and diamond resin wheels are used for grinding silicon ingots for solar cells and semiconductors. Drawing on our proven track record across various industries, we provide wheels tailored to our customers’ needs and the machinery they use.

Vertical grinding of tool materials. Used for grinding that requires long life and shape retention, such as endmill groove grinding, gash grinding, grinding of machine tool bed sides and jaw faces, and profile grinding.

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 components made from materials such as ceramics, a technology that uniformly disperses the abrasive grains within the abrasive layer has made it possible to improve cutting performance while extending tool life compared to conventional metal tools.
Furthermore, by making the abrasive layer ultra-thin, these tools reduce machining load and minimize chipping—even when machining hard and brittle materials and other specialty materials—thereby improving machining efficiency and demonstrating superior performance compared to 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.

Roller dresser for profiling are available in four types: metal truer, electroplated truer, prisma dresser, and grain stone dresser. We select the optimum specifications according to grinding wheel specifications and dimensions, dressing conditions, and requirements.

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 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.

These are grinding wheels designed for precision grinding of bearings, automotive parts, home appliance parts, and other precision mechanical components. We manufacture vitrified-bonded grinding wheels—ideal for precision grinding—using our proprietary manufacturing process.

These cup wheels were developed with safety as a top priority for use with handheld power tools and are compatible with a wide variety of work materials. We offer a wide range of options, including “Blue” for stone and “Light Green” for concrete, among others.

"CREEPSTAR" for heavy grinding of tungsten carbide
"POLASTAR POLYX" for heavy grinding of tungsten
"ASPIRE METAL" for heavy grinding of tungsten carbide
SUN Athlete Series
"SUPREMO" High-performance metal wheel for Flute grinding of Carbide tools

Developed to expand the processing area of resin bond wheels, such as lapping, mirror finishing, polishing, etc., with a new bond with a special structure that has a high elasticity not found in conventional Bright Star type bonds.
