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. Drawing on our proven track record across various industries, we provide wheels tailored to our customers’ needs and the machinery they use.

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.

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 bushings are ideal for injection molding of filler-reinforced plastics. They offer excellent wear resistance and help prevent “progressive wear at the nozzle contact point,” which is a common cause of resin leakage issues. These bushings are crafted from high-quality diamond, a material that—in addition to its high hardness—exhibits low wettability. Furthermore, their service life is more than 10 times longer than that of conventional iron-based metal bushings. This also helps reduce 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.

This is a vitrified grinding wheel made with general-purpose abrasive grains. It can be formulated into a wide variety of grinding wheel structures, ranging from soft to hard, and is highly effective as a dressing material 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.
