Vitrified CBN Grinding Wheels delivery high efficiency and long tool life with the rigorous and high porosity bond system. The vitrified bond is composed of metal oxides, which is strong, durable, and hard. It is very effective in high-precision, tight-tolerance grinding because of its ability to hold the abrasive, as well as its ability to be easily dressed and profiled. They are used in wide spectrum of applications in the aerospace, automobile, and tool manufacture industries.
