LEB processing is a method that extends tool life by applying high voltage to cutting tools at room temperature and pressure, thereby modifying the structure of the metal surface (increasing the hardness at the tip and improving internal stress). Instead of applying a coating like TiN, the surface is modified by applying high voltage. Therefore, treatment is possible regardless of whether the tool is made of high-speed steel, carbide, or has a coating. Increased hardness due to high voltage application! Improved internal stress! No changes in dimensions or shape! Tool life can be more than doubled! Good surface roughness! Reduced tool replacement effort! Significant reduction in tool costs! Many case studies available. <Case Study> A cutter was processed for a car parts manufacturer, resulting in an increase in processing quantity by 1.5 to 1.8 times! We successfully achieved a cost reduction of 5 million yen with LEB processing! We are currently continuing to receive repeat orders!
