Metal

Metal bond wheels for surface grinding of wafers such as SiC and GaN. The ultra-porous structure realizes fine grain grinding, which could not be applied with conventional metal bond wheels, and has excellent sharpness and wear resistance compared to vitrified bond wheels of the same particle size.

SUNCREA contributes to improving processing efficiency and reducing costs in hard and brittle materials such as sapphire, carbide, and ceramics, hard magnetic materials such as ferrite and neodymium iron, and iron-based materials such as sintered parts.

Features
1) Good chip evacuation
(2) Stable grindability
(3) Excellent wear resistance and long life
(4) Truing with Electroplated truer is possible (limited to CBN ).

Diamond metal wheels for chamfering automobile glass, which play an important role in improving automobile safety.

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.

Diamond wheels with varying bonding materials such as curve generating wheels, pallets, lens centering wheels and grinding wheels are used for grrinding camera and binocular lenses, prisms, etc.

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.

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.
