In the surface treatment of small and medium-sized workpieces, mechanical methods have replaced manual labor, encompassing both metallic and non-metallic pieces. This has significantly increased speed and raised quality standards. The boost in speed is due to the ability to process in large quantities at high speeds, while the quality improvement ensures that every surface of each workpiece is polished uniformly, even for pieces with complex shapes, resulting in consistent smoothness across both surfaces and recesses.
In mechanical polishing and grinding, the primary equipment is the polishing and grinding machine, which includes centrifugal polishing and grinding machines, eddy current polishing and grinding machines, vibration polishing and grinding machines, magnetic polishing and grinding machines, and so on. All of them can achieve a good surface treatment effect on the workpiece. Since mechanical polishing offers so many benefits, we must strive to enhance the efficiency and quality of the polishing and grinding process even further.
To achieve good work efficiency in the polishing and grinding process, selecting the right materials is a crucial aspect. Material selection refers to choosing the appropriate polishing material based on the workpiece's material, shape, and specifications for its surface polishing treatment. In other words, before conducting the polishing and grinding process, a suitable material is formulated according to the characteristics of the workpiece and the polishing material, ensuring effective surface polishing with desirable results.
Firstly, it is crucial to determine the abrasive for polishing, which serves as the primary medium for the surface polishing process of the workpiece. Therefore, selecting the appropriate abrasive is the main factor in determining the surface treatment of the workpiece. Consequently, a plan and operational procedures for the use of materials must be established before the workpiece is polished, along with specifying the types of polishing and luster-enhancing fluids.
The surface polishing of workpieces typically involves three steps: coarse polishing, fine polishing, and mirror polishing. Select the appropriate specifications and varieties of polishing abrasives, polishing fluids, and polishing brighteners. For coarse polishing, use coarse polishing abrasives and polishing fluids suitable for the workpiece characteristics. During fine polishing, employ fine polishing abrasives. For precision polishing, use surface polishing abrasives and choose the corresponding brighteners. This ensures optimal performance of mechanical polishing and grinding.
