There are many kinds of grinding wheels commonly used in surface grinding machines, and they have various shapes and sizes. Due to the different abrasives, binder materials and manufacturing processes of grinding wheels, all kinds of grinding wheels have different working properties. Each kind of grinding wheel has a certain scope of application according to its own characteristics.

For example, brown corundum grinding wheel: brown corundum has high hardness and toughness. It is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. this abrasive has good grinding performance and wide adaptability. It is commonly used for rough grinding with large margin. It is cheap and can be widely used.

White corundum grinding wheel: the hardness of white corundum is slightly higher than that of brown corundum, and the toughness is lower than that of brown corundum. During grinding, the abrasive particles are easy to break. Therefore, the grinding heat is small. It is suitable for manufacturing grinding wheels for fine grinding quenched steel, high carbon steel, high-speed steel and grinding thin-walled parts, and the cost is higher than that of brown corundum.

Chrome corundum grinding wheel: suitable for grinding workpieces with high surface processing quality requirements such as cutting tools, measuring tools, instruments and threads. Single crystal corundum grinding wheel: suitable for grinding stainless steel, high vanadium high-speed steel and other materials with high toughness and hardness and easily deformed workpieces.

Microcrystalline corundum grinding wheel: suitable for grinding stainless steel, bearing steel and special nodular cast iron. It is used for forming grinding, cutting grinding and mirror grinding. Therefore, during grinding, the appropriate grinding wheel must be selected according to the specific conditions (such as material properties, heat treatment method, workpiece shape, size, machining form and technical requirements, etc.). Otherwise, the machining accuracy, surface roughness and production efficiency will be directly affected by the improper selection of grinding wheel
