Asahi Diamond Industrial Co., Ltd.

Natural diamond Natural diamond is produced in only a few favored places in the world because of the very unusual conditions under which it occurs. Rough diamonds are used in wire drawing dies, drill bits, dressers, etc. synthetic diamond Synthetic diamond is different from natural diamond in that it can be mass-produced and that optimum properties for particular applications can be imparted to it. Synthetic diamonds play an important role in improving the workability of hard, brittle materials, such as stone, concrete, and carbides. cubic Boron Nitride (cBN) Like synthetic diamond, CBN is artificially...

utilizing the unique characteristics of diamond diamond is one of nature’s most precious gifts to humankind. Its sturdy crystalline structure and strong atomic bond give it properties which make it ideal for use in the working of advanced technology materials. As industry develops more complex materials which require increasingly sophisticated equipment to cut, drill, shape, grind and polish them for highly specialized uses, diamond will become indispensable. As the world’s leading producer of highly functional diamond and cubic boron nitride tools, and backed by superior technological capabilities,...

Vitrified Bond cBN Wheels (for grinding camshafts) “Vt series” Vitrified bond CBN wheels are used for grinding the cam lobes of automobile camshafts. Optimum bond specifications have been set for each type of cam material, and since the wheels are used for high-speed grinding, bond quality, adhesives, and the materials used for the core are carefully designed for safety. AutomoBILEs, ELEctrIcAL mAcHINErY, BEArINGs the growth of the automobile, electrical machinery, and bearing industries has been instrumental in Japan’s rapid economic development. High-precision tools are an integral part of...

Vitrified Bond cBN Wheels (for centerless grinding) Vitrified bond CBN wheels are used for centerless grinding of various types of bearing rollers, injection nozzles, pump parts, etc. Since CBN has excellent grinding characteristics, vitrified bond CBN wheels need not be as large as conventional abrasive wheels. However, due to their comparatively large width and diameter, and in order to maintain wheel balance essential for high-speed revolution, a ceramic core is used to reduce overall weight and prevent thermal deformation. Vitrified Bond cBN Wheels (for grooving & forming) Vitrified bond...

Electroplated cBN Wheels The CBN layer, electroplated onto the core of the wheel, has excellent cutting ability due to its greater protrusion of CBN particles. This structure is suitable for high precision formed wheels such as those used in gear form grinding. It is also used for high-speed grinding applications, owing to its extremely rigid core. Profile of electroplated CBN-forming wheel diamond & cBN Wheels (for re-grinding machining tools) Diamond or CBN wheels are used to re-grind machining tools made of high-speed tool steel, cemented carbide alloy, cermets, ceramic, diamond compact, CBN...

diamond Wheels (for pencil edging automobile window glass) Metal bond diamond wheels used for pencil edging automobile window glass and diamond core drills for drilling holes in it have contributed greatly to automobile safety. diamond & cBN Honing stones 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. Gear dresser form accuracy...

diamond roller dressers sintered & Electroforming types 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. Electroforming diamond roller dresser other diamond dressers A diamond dresser has one or more diamonds mounted on the tip of its shank and is used for truing and dressing abrasive grinding wheels. The efficiency...
