What is a hand polisher?

Hand polishing machine refers to the hand-controlled mechanical polishing traditional method is carried out on the polishing machine equipped with a polishing wheel. Cell phone polishing machine wheel is generally used cloth, fluffy felt, leather or special kraft paper, etc. cut into a round number of overlapping layers sewn into a wheel shape, and installed in the axis of the polishing machine, so that after its rotation of the parts layer overlapping sewn into a wheel shape, and installed in the axis of the polishing machine, hand polishing machine so that after its rotation of the parts ping in the wheel to implement polishing. The hardness of the polishing wheel is related to the suture material used and the distance of the suture line. Polishing wheel high-speed rotation, the substrate and cloth wheel friction generated by the high machine temperature so that the substrate surface plasticity to improve and produce plastic deformation, the raised part is lowered and to the concave part of the flow of the filling, and thus reduce the surface roughness. Manual polishing process on the polishing wheel coated by micro-fine particles of abrasive, a variety of grease and auxiliary materials composed of polishing paste. The chemical composition of the polishing paste acts on the surrounding medium in polishing, enhancing the effect of polishing. Hand polishing machine is also the process of metal surface oxide film is constantly generated and constantly grinding off.
