Processing technology of Grinding and Polishing Lines
Coarse Grinding
Use a coarse grinding belt or wheel with greater grinding pressure and higher feed rate. Suitable for removing burrs, scale and uneven parts of the workpiece surface.
Fine Grinding
Use a medium-fine grit abrasive belt or wheel to reduce the grinding depth and feed rate. This process helps to reduce surface roughness and prepare for the polishing stage.
Brushing
Use a brushing machine with a special brushing brush to treat the surface of the workpiece with a rotating brush to form a uniform texture. Suitable for stainless steel and other metal materials, providing visual effects and practical functions.
Polishing
Use a fine-grained polishing disc or cloth with a polishing agent for treatment. It is carried out at a lower speed to remove minor surface defects and finally form a high-gloss surface.
Cleaning
Use cleaning equipment, such as an ultrasonic cleaner or a spray cleaning system, to remove dust, grinding chips and polishing agent residues. Drying is usually carried out after cleaning to prevent oxidation.
Inspection
Use measuring tools, such as a surface roughness tester or a coordinate measuring machine, to inspect the workpiece for quality. Confirm whether the surface smoothness, dimensional accuracy and appearance of the workpiece meet the specifications.
