There are many kinds of grinding wheels with various shapes and sizes. Due to the different abrasive materials, bonding materials and manufacturing processes of grinding wheels, various grinding wheels have different working performance. Each kind of grinding wheel has a certain scope of application according to its own characteristics. Therefore, when grinding, appropriate grinding wheels must be selected according to the specific conditions (such as material properties of the workpiece to be ground, heat treatment method, workpiece shape, size, processing form and technical requirements, etc.). Otherwise, the improper selection of grinding wheel will directly affect the machining accuracy, surface roughness and production efficiency.
Now let's talk about how to choose grinding wheel by combining sharp corundum with abrasive:
1. When grinding materials with high tensile strength, select abrasive with high toughness.
2. When grinding materials with low hardness and high elongation, select brittle abrasive.
3. When grinding materials with high hardness, choose abrasive with higher hardness.
4. Select abrasives that are not easy to be processed by chemical reaction.
