At Tōmeidaiya Co., Ltd., we accept orders for cutting diamond sintered bodies that we handle. We offer various cut products, including the diamond sintered body "TDC-EM," which has the best wear resistance. All table surfaces of the diamond sintered bodies are finished with a mirror surface, but we can also provide non-mirror products by skipping the mirror finishing process. We can manufacture from any of the sintered body series we handle, including "EM," "E II M," "HM," "SM," "GM," "98F II M," and "FM." We also accept custom orders for non-standard sizes and cut products, so please feel free to contact us. 【Features】 ■ A lineup of products with various characteristics ■ Production possible from each series ■ Mirror finish ■ Non-mirror products can also be provided *For more details, please refer to the catalog or feel free to contact us.

The "ISBN Series" is a CBN powder product that is effective for grinding and polishing iron-based materials. CBN abrasive grains have the characteristic of being less likely to chemically react with iron, and they maintain stable high-temperature properties compared to diamond. We offer mesh size products that exhibit high grinding performance with moderate friability and sharp shapes, as well as micron size products that achieve high polishing rates and low Ra with a sharp particle size distribution. 【Features】 ■ Effective for grinding and polishing iron-based materials ■ Less likely to chemically react with iron ■ Excellent high-temperature properties ■ Less high-temperature degradation compared to general CBN abrasive grains ■ Lineup of mesh size products and micron size products *For more details, please refer to the catalog or feel free to contact us.

TMS has been developed to provide added value in fields that require higher strength than traditional metal products, such as cutters, band saws, and wire saws, due to its higher hardness. Additionally, the 400/500 and 500/600 are of the same particle size as micron-sized products and can be used as harder micron products with higher hardness compared to our metal micron products.

• Fine Ceramics

We have added two types of cBN abrasives to our lineup. Electroplated cBN abrasive "ISBN-E" Polycrystalline cBN abrasive "ISBN-P"
