What are polishing wheels and various structures

2020-04-25 1051

Polishing wheels are generally made by stacking multiple layers of canvas, felt, or leather, with metal circular plates clamped on both sides. The rim of the wheel is coated with a polishing agent composed of a uniform mixture of micro abrasive and grease. When polishing with a polishing wheel (cloth), a high-speed rotating polishing wheel (with a circumferential speed of more than 20 meters/second) presses against the workpiece, causing the abrasive to roll and micro cut the surface of the workpiece, and then obtain a bright machining surface. The surface roughness can generally reach Ra0.63-0.01 micrometers;

When using non greasy matte polishing agents, the bright surface can be matted to improve the appearance. Polishing wheels made of various structures such as cotton cloth, linen, woolen cloth, or composite materials have unique advantages in flexibility, wear resistance, economy, polishing effect, and play an important role in the polishing industry. The flexibility of these polishing wheels depends on many factors such as substrate material, installation structure, number of layers, size of folds, impregnating agent and impregnation method, ratio of inner and outer diameters, and stitching density. To improve the wear resistance of cotton and linen polishing wheels, the substrate is mostly 45. Weaving methods, which do not contain abrasives themselves, rely on abrasives to achieve grinding of the workpiece: together, the substrate generally needs to be impregnated, and the impregnated polishing wheel can improve the adhesion of the abrasives, and then improve the grinding effect, extending the lifespan of the polishing wheel; By selecting different impregnating agents and methods, different flexibility and adhesion can be obtained to adapt to different processing requirements. Polishing wheels generally use different colors of the substrate to distinguish their flexibility and adhesion.
