This document is a collection of case studies compiled by Tokyo Bolt and Screw Machine Co., Ltd. The "carbide nozzles for winding machines" are important to maintain a mirror finish as the wire runs at high speed through the holes, but even extremely small holes pose no problem. "We can manufacture jigs made from various materials such as die steel, high-speed steel, carbide, or by brazing carbide onto die steel, among others." We can accommodate various shapes and sizes as requested by our customers, so please feel free to consult with us first. [Featured Cases] ■ Carbide machine parts ■ Carbide nozzles for winding machines ■ Various nozzles ■ Various pins and punches ■ Various jigs *For more details, please refer to the PDF document or feel free to contact us.

Company information
Tokyo Bolt and Nut Company has focused on the hidden potential of cemented carbide, refining technologies for machining irregular shapes, fine holes, deep holes, and lapping processes for cemented carbide. We were once a "mold manufacturer," but our goal is to be recognized by our customers as a "ultra-precision machining manufacturer." Recently, we have succeeded in mass-producing molds with direct engraving on cemented carbide, a world first! Cemented carbide is an extremely hard metal. Traditionally, machining cemented carbide required "very expensive special machining centers and special tools, making it possible to process only under certain conditions, resulting in high costs and limited shapes and precision. Therefore, it was common knowledge that machining cemented carbide was done through electrical discharge machining. We have conducted years of research with the goal of mass-producing cemented carbide molds at low cost, specifically aiming for direct engraving and omitting lapping. We have now achieved both. As a result, while maintaining quality equal to or better than traditional methods, we have achieved a running cost of less than one-fifth of the conventional method with 24-hour continuous operation. In the future, we will utilize this technology to contribute to the miniaturization and lightweighting of parts in aerospace, precision machinery, and medical fields.
