Zhengzhou major scientific and technological research project diamond grinding wheel passed the appraisal

Zhengzhou Abrasives Research Institute, Zhengzhou City, major scientific and technological research project "processing diamond tools for hard and brittle materials - high-thickness metal bond diamond grinding wheel" has passed the identification.

The appraisal committee believes that the project has mainly solved four problems: First, through the reasonable selection and configuration of various metal powders, a special metal bond formulation suitable for processing high-aluminum ceramics and NdFeB magnetic materials has been developed. Second, solve the problem of uneven axial density of the working layer of high-thickness grinding wheel; Third, through the treatment of the basic outer circular surface of the grinding wheel and the bonding process of the base body and the grinding wheel ring, the bonding strength is improved, and the grinding wheel is used. In the middle, it does not take off the ring; Fourth, using the cutting-in technology, the research determines the processing parameters and ensures the straightness of the grinding wheel. The innovation of the project: solving the problem of the uniformity of the axial direction of the high-thickness metal bond grinding wheel; the combination technology of the working layer of the high-thickness grinding wheel and the substrate.
