CBN abrasive wheel produced, depending on the process and the different Internal Grinding components of the binding agent used can be divided into the following four. Their nature and purpose (only for machining purposes) are different. 1 electroplated CBN / Diamond Wheel Wheel production process is simple, low cost of production. Simple but only one layer forming coating, in the process, is difficult to know when the grinding layer is damaged, suitable for small batch processing and correction roller machine. 2 sintered CBN / Diamond Wheel High hardness and density, a high-precision machining, and the cost is high. The amendment is mainly used for grinding wheel rollers and large quantities of superhard materials processing. 3 Resin CBN / Diamond Wheel Wheel production process is simple, low cost of production. Forming simple but good fix integer. For multi-shape small batch processing. Grinding and cutting tools such as tools for processing, and processing of glass. 4 vitrified bond CBN / diamond wheel Vitrified bond CBN / diamond grinding wheel has a strong, high-speed processing does not burn the workpiece can be corrected and durable advantages.
