cBN Tools

Our cBN tools use cubic boron nitride, which has a diamond crystal structure composed of boron and nitrogen. These tools are used for machining iron-based metals and are especially useful for finishing workpieces, such as high-hardened steel, with high efficiency and high precision. When combining them with the polishing method by electric-field abrasive grains (PAT-3595219), machining speed is increased thanks to the excellent machining capability as well as ultra-long service life, high precision, and high quality. The tools are especially useful for direct carving of metal molds.
