Abrasive belt grinding equipment has various forms and varieties.
The main chemical composition is AL2O3, which is made by smelting bauxite, iron filings and anthracite in an electric arc furnace at a high temperature above 2250℃. The color of Brown fused alumina abrasive is brown. This abrasive has certain hardness and toughness, strong grinding ability, and can withstand great pressure. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance and good chemical stability. Due to its high tensile strength, it is suitable for grinding materials with high tensile strength, suitable for ordinary steel, high-carbon steel, alloy steel, and can be used for hard wood processing. It can also be used as a substitute when other abrasives are insufficient. It is called an abrasive and is a widely used abrasive.
The abrasive grain size of the abrasive belt has a great influence on the grinding productivity and the surface roughness of the processing. In order to ensure the roughness and processing efficiency of the workpiece, it should be based on the different requirements of the processing, the performance of the machine tool, and the specific conditions of the processing, such as the processing allowance of the workpiece, The surface condition, material, heat treatment, precision, roughness are different to choose different grit belts. Generally speaking, coarse grit is used for coarse grinding and fine grit is used for fine grinding. (The following data is for reference only, and the actual processing conditions are related to the performance of the machine tool and processing parameters, etc.)
