This wheel is used for grinding thin glass used in displays such as TVs, PCs, and smartphones.

Small-diameter formed wheels are used to finish the notches of large-diameter wafers. Our notch grinding wheels maintain the run out accuracy of diamonds to the shank, and realize a favorable wafer circumference. As with our edge grinding wheels, we are able to provide a wide variety of specifications, including single-grooved wheels, multi-grooved wheels, and wheels for both rough and finish grinding.

Metal bond wheels and resin bond wheels are used in edge grinding on the outer circumference of silicon wafers, which requires uniform sharpness in addition to precision accuracy in the shape of the wheel and abrasion resistance. We are able to provide a wide variety of specifications, including single grooved wheels, multi-grooved wheels, and wheels for both rough and finish grinding.

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.

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.

Asahi Diamond produces various types of precision wire drawing dies, such as those applicable to gold and other soft wires used in the manufacture of semiconductors. It also markets various types of drawing dies. Natural diamond, SUNPAX, and synthesized single-crystal diamond are used for wire drawing dies, such as formed dies, guide dies for tin-plated wires, diamond nipples, and others.

Diamond Sprue Bush is ideal for injection molding of filler-reinforced plastic materials. It has excellent wear resistance and reduces "wear progression at the nozzle touch area" that causes resin leakage problems. High quality diamond finish that exhibits low wettability more than a high hardness substance. In addition, the life is 10 times longer than that of conventional ferrous metal bushings. It also reduces waste.

By using diamond for water jet nozzle, water stream width can be minimized and directness and ultrahigh pressure achieved, resulting in higher precision and longer life. Furthermore, by expanding the width of the water stream, the nozzle can also be used for cleaning and removal of burrs.

The accuracy of the wire guides determines the precision of wire electrical discharge machining(EDM), which is used for metal forming processes in various industries. Asahi Diamond has developed this highly functional diamond wire guide jointly with an electrical discharge machining equipment manufacturer.

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.
