Grinding disc is an important grinding tool in grinding processing. It is a porous body made by adding a binding agent to the abrasive, pressing the body, drying and baking it.
Due to different abrasives, binders and manufacturing processes, the characteristics of grinding discs also vary greatly, which has an important impact on grinding quality, productivity and economy.
The characteristics of grinding discs are mainly determined by factors such as abrasive, particle size, binder, hardness, structure, shape and size.
The grinding disc should be carefully inspected and identified before installation.
The inspection and identification steps are as follows:
1. Check whether the grade of the grinding wheel is correct and whether it matches the performance, shape and size of the selected grinding wheel.
2. Check and identify the appearance and structure of the grinding wheel. Use your eyes to see if the grinding wheel is damaged (or cracked). Grinding wheels with damaged (or cracked) appearance cannot be used. In addition, both ends of the grinding wheel are required to be flat without obvious skew.
3. Check and identify internal cracks in the grinding wheel components. Hold the grinding wheel in your hand, tap the grinding wheel lightly with a wooden hammer, and listen for the sound. The crack-free grinding wheel makes a crisp sound. A cracked grinding wheel makes a hoarse sound and cannot be used.
