The commonly used cylindrical grinding machine in production and processing equipment is widely used. In the operation of grinding machines, the selection of abrasives is more important. Choosing the appropriate abrasive according to the different grinding machines has a great impact on the machining quality of materials and the service life of the grinding machines.
1. Selection of abrasives for cylindrical grinding machines: For quenched or non quenched steel rolling rolls, corundum grinding wheels are selected; Cold hard cast iron rollers, rubber rollers, copper rollers, and granite rollers use silicon carbide grinding wheels. For steel rollers of different materials, matching corundum grinding wheels should be selected to achieve higher grinding accuracy and surface quality.
2. Selection of Grinding Wheel Size for External Grinding Machine: Coarse grained grinding wheels are used for rough grinding; Fine grained grinding wheels are selected for precision grinding.
3. Selection of Grinding Wheel Hardness for External Grinding Machine: The harder the grinding roller surface, the softer the grinding wheel hardness should be selected.
