Rivet and contact punch
Is this the world's first!? We have succeeded in mass-producing molds by direct engraving on super hard alloys. We offer rivets and contact punches at half the conventional price.
Tokyo Bolt and Screw Machinery has succeeded in mass-producing molds through direct engraving on cemented carbide. As can be understood from the fact that cemented carbide is used for tools and molds to process regular metals, it is an extremely hard metal. Traditionally, machining cemented carbide required "very expensive special machining centers and special cutting tools, which made processing possible but limited in shape and precision, resulting in significant costs." Therefore, it was common knowledge that processing cemented carbide was done through electrical discharge machining. Our company has 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 been able to achieve running costs of less than half compared to conventional methods with 24-hour continuous operation.
