The shape and size of the grinding wheel and its choice

The grinding wheel is made in a variety of shapes and sizes depending on the machine structure and the need for grinding. Table 6 shows the shape, size, code and use of several commonly used grinding wheels. The outer diameter of the grinding wheel should be selected as large as possible to increase the peripheral speed of the grinding wheel, which is advantageous for improving the grinding processing productivity and surface roughness. In addition, under the conditions of machine tool stiffness and power permitting, if the grinding wheel with larger width is used, the productivity and roughness can be improved. However, in the case of grinding heat sensitive materials, in order to avoid burns on the surface of the workpiece and Cracks are generated and the width of the grinding wheel should be appropriately reduced.
