Diamond metal wheels and diamond resin wheels are used for grinding silicon ingots for solar cells and semiconductors. Based on our experience in various fields, we offer wheels that meet the needs of our customers and the machines they own.

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.

This is a special gear-shaped dresser used for dressing worm-shaped grinding wheels for gear grinding and dressing internal gear-shaped grinding wheels for fine finishing, and is effective for mass production of high-precision gears.

Sintered roller dresser with excellent dressability and formability. It is especially effective in shaping hard grinding wheels. The diamonds are set in a spiral shape, which widens the grain spacing in the circumferential direction and improves sharpness, and the grain spacing in the width direction is narrower, enabling uniform shaping of the grinding wheel. As a result, highly efficient and precise grinding is now possible.

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.

Instead of granular diamonds, this dresser has one or more columnar diamonds embedded. Since the contact area remains the same from the initial dressing stage to life-out and stable dressing performance is achieved, automated lines and multiple dressers are best suited for large-diameter grinding wheels. In addition, the feed rate can be increased compared to that of a single point dresser, thus reducing dressing time. Diamond size can be selected according to the type and dimensions of the grinding wheel.

This is a single-point dresser with a pyramid-shaped cutting edge generated at the tip by grinding. Compared to conventional natural rough diamond dressers, this dresser provides more stable cutting performance and can work under similar dressing conditions. This dresser specializes in cutting performance and is good at grinding wheels with high elasticity like rubber grinding wheels.

Natural diamond dressers are dressers with one or more diamonds sinter mounted on the tip of the shank. The truing and dressing capabilities of the dresser have a significant impact on grinding efficiency and finishing accuracy. Various dressers are available to meet the various needs of customers in wheel shaping.

This is a single-point dresser with a conical cutting edge generated at the diamond tip by grinding. Compared to existing natural rough diamond dressers, this dresser provides more stable cutting performance and can work under similar dressing conditions. In addition to basic dressing performance, this dresser excels in simple shape modification such as R shape and tapered shape, and is highly versatile.

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.
