Metal bond wheel

Metal bond wheel

Wheels used for various applications, including glass grinding, carbide, and automotive accessories.

The "metal bond wheel" was invented for grinding various types and shapes of glass. In addition to glass grinding, it has been expanded to various applications such as attaching blades to carbide saws, grinding ferrite, ceramics, carbide alloys, automotive accessories, quartz, and stones. In the late 1970s, our company began designing and manufacturing edge wheels for automotive glass and edge wheels for CRT polishing ranging from 14 inches to 33 inches. Since then, in response to the demands of the high-tech industry, we have started producing electrolytic grinding wheels and have accelerated the continuous development of high-quality products. 【Product Lineup】 ■ Wheels for automotive glass grinding ■ Wheels for lens grinding ■ Honing stones *For more details, please refer to the PDF document or feel free to contact us.

Electrostatic wheel

Electrostatic wheel

Suitable for cutting and grinding various materials! Capable of processing with high material removal rates and excellent cutting performance.

Electroplated diamond and CBN tools are made by adhering diamond or CBN particles to the surface of the tool using a nickel plating method, either in a single layer or multiple layers (depending on the application). Using this electroplating method, tools with various shapes and surface textures can be manufactured. To meet the rapidly increasing global demand, our company began producing a variety of high-quality electroplated tools in 1992. In addition to conventional electroplated tools, we also produce reverse electroplated diamond rotary dressers for the automotive and aerospace industries, as well as electroplated wafer dicing blades for the semiconductor industry. 【Product Lineup】 ■ Wheels for grinding brake pads ■ Wheels for grinding ferrite ■ Wheels for grinding SiC molds ■ Electroplated reamers *For more details, please refer to the PDF document or feel free to contact us.

Vitrified bond wheel

Vitrified bond wheel

Vitrified bond wheels that maintain performance even under prolonged and harsh use, with excellent durability.

The "Vitrified Bond Wheel" is a special wheel with much higher hardness than resin or metal bond wheels, and its demand for automated equipment and systems is very high. In the late 1980s, our company developed high-quality vitrified bond CBN wheels for grinding automotive parts such as constant velocity ball joints. Since then, we have expanded the development of vitrified bond wheels that can be used for various applications, including high-precision machine parts, bearings, gears, tools and dies, semiconductors, ceramics, cermets, and particularly for grinding cutting tools made of PCD and PCBN. Our company is making every effort to develop better quality and high-performance vitrified bond products to satisfy the diverse needs of the industry. 【Product Lineup】 ■ Wheels for grinding PCD/PCBN inserts ■ Wheels for grinding the inner surface of injection nozzles ■ Wheels and honing stones for bearing grinding ■ CBN wheels for grinding crankshafts *For more details, please refer to the PDF document or feel free to contact us.
