There are many types of grinding wheel grinding tools for each cutting piece manufacturer, and there are various shapes and sizes. Each grinding wheel has a certain range of application depending on the abrasive material of the grinding wheel, the bonding material and the manufacturing process. If improperly selected, it will directly affect the processing accuracy, surface roughness and production efficiency. Therefore, when grinding, you must select the appropriate grinding wheel according to the specific situation. So how do you choose the right wheel? Today, taking 115 golden star cutting disc as an example, the grinding wheels commonly used in grinding are summarized, so that everyone can clearly select the grinding wheel of the cutting piece.

Abrasive selection The choice of abrasive depends primarily on the workpiece material and the heat treatment method.

 The most commonly used abrasives are brown fused alumina (A) and white fused alumina (WA):

Brown corundum grinding wheel: Brown corundum has high hardness and high toughness. It is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This kind of abrasive has good grinding performance and wide adaptability. It is often used to cut a large amount of coarse grinding, which 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. When grinding, the abrasive grains are easily broken. Therefore, the grinding heat is small, and it is suitable for manufacturing hardened quenched steel and high carbon steel. High-speed steel and grinding wheels for grinding thin-walled parts are more expensive than brown fused alumina.
