1 . Cleaning on the surface of the workpiece The can be used as a rust layer on the metal, the residual salt and oxidation layer on the surface of the heat processing parts, the oxidation layer on the surface of the rolled parts, the oxidation layer on the surface of the forged parts, the oxidation layer on the surface of the welding part, and the surface of the casting surface Sandy and oxidation layers, residual dirt on the surface of the machine, and the surface of the old parts, and the surface of the old parts are treated to remove the surface attachment layer and reveal the nature of the substrate. The surface cleaning quality can reach the SA3 level. 2. Preparatory processing before the surface coating of workpieces This can be used as pre -processing processes of various electroplating processes, brush plating processes, spraying processes and bonding processes to obtain active surfaces and improve plating, coating and adhesive parts Attachment. 3. Change the physical mechanical properties of the workpiece This can change the surface stress status of the workpiece, improve the lubrication conditions of the puppet, and reduce the noise in the process of puppet motion. It can harden the surface of the workpiece and improve the wear resistance and fatigue strength of the parts. 4. The light decoration processing on the surface of the workpiece The value of the surface roughness of the workpiece can be changed. The surface of the workpiece that can produce a sub -light or roaming reflection to achieve the purpose of light decoration processing.
1 . Cleaning on the surface of the workpiece
The can be used as a rust layer on the metal, the residual salt and oxidation layer on the surface of the heat processing parts, the oxidation layer on the surface of the rolled parts, the oxidation layer on the surface of the forged parts, the oxidation layer on the surface of the welding part, and the surface of the casting surface Sandy and oxidation layers, residual dirt on the surface of the machine, and the surface of the old parts, and the surface of the old parts are treated to remove the surface attachment layer and reveal the nature of the substrate. The surface cleaning quality can reach the SA3 level.
2. Preparatory processing before the surface coating of workpieces
