Principle of mechanical polishing
Is the use of mechanical polishing polishing machine, abrasive belt machine, grinding machine tools for polishing articles etc..
Polishing is made of soft materials, polishing wheel, with adhesive or grease fixed abrasive or semi fixed abrasive or free abrasive, polishing wheel to do high-speed rotation, workpiece and polishing wheel to do feed motion processing workpiece, so that the workpiece is smooth, bright surface of the final processing method.
Its main purpose is to remove the machining marks before the processing procedure (marks, grinding lines, marking, pitting and burr), generally can not improve the accuracy of the shape and dimension.
Usually used for substrate surface, plating or oil dyeing finishing on the surface and a concave surface, is the final finishing method is simple, rapid, inexpensive parts of the surface, the polishing method of modern development, but also improve the accuracy of the shape and dimension of workpiece.
In order to make the difference with the traditional polishing method, the modern polishing is referred to as the precision polishing, the high precision polishing and the mirror surface polishing.
