Honing stones are used for accurate and efficient honing of the inner surfaces of holes in automotive parts, such as cylinder liners, connecting rods, crankshaft bearings, valve rocker arms, transmission gears and brake hydraulic cylinders, and in vessel and generator parts, such as engine cylinder liners and compressors.

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.

Electroformed roller dresser with diamond grains regularly arranged to reduce grain concentration and improve sharpness. Grain concentration can be adjusted according to your needs. The sharpness of parts requiring complex shapes can be controlled.

The newly developed "KD Dresser", added to our lineup, is a rotary dresser that achieves both high-precision overall shape and cutting performance.

We support customers' prototype development with short delivery times that exceed conventional common sense. This roller dresser, a high-precision general-purpose type, achieves quick delivery while maintaining the performance of conventional products. This roller dresser is designed to meet the needs of those in charge of prototype development, etc., who place priority on quick delivery.

Diamond roller dressers are used for forming and dressing fired abrasive grinding wheels and CBN wheels. Since these dressers are capable of accurate and speedy form dressing, they can effectively be used to mass produce work parts with a high degree of accuracy. Diamond roller dressers are available in sintered and electroforming types.

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.

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.

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.

This grinding wheel is used for polishing as a final finishing step for metal products. It is ideal for superfinishing the raceways of various bearings and for superfinishing the outer diameters of needle bearings, roller bearings, and similar components.

These grinding wheels are designed for the final finishing of bearings. We will select the grinding wheel best suited for the raceways of various types of bearings.
These grinding wheels are highly regarded for the ultra-precision grinding of bearing raceways. CBN, we offer a wide lineup that includes CBD grinding wheels designed for superior cutting performance and DBN grinding wheels designed for superior surface finish accuracy, enabling us to design grinding wheels tailored to your specific 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.
