Polishing processing usually refers to the use of the mechanical and chemical effects of micro abrasive particles to achieve smooth or ultra smooth surfaces with the assistance of soft polishing tools or chemical processing fluids, electric/magnetic fields, etc., in order to reduce or completely eliminate the processing deterioration layer, thereby obtaining high surface quality processing methods.

Polishing differs from grinding in the selection of abrasives and grinding tool materials. Polishing usually uses fine abrasive grains below lum. Polishing discs are made of soft non-metallic or metallic materials such as asphalt, paraffin, synthetic resin, Artificial leather, tin, etc. The back cutting amount of abrasive grains can be automatically adjusted according to the contact state to slow down the scratch damage caused by larger abrasive grains on the processed surface and improve the surface quality. At present, the removal units of abrasive processing have reached the order of nanometers or even sub nanometers. Within this processing scale, the polishing process is accompanied by chemical reactions, and the chemical effects of the processing atmosphere cannot be ignored. If various chemical interactions between workpiece and abrasive particles, workpiece and processing fluid, and workpiece and grinding tool can be effectively utilized in machining, it can not only improve machining efficiency but also obtain a non-destructive machined ceramic flange surface.

For the grinding of hard and brittle materials, when the abrasive particles are small to a certain particle size and a soft material grinding disc is used, the differences in grinding and polishing caused by the different characteristics of the ceramic nozzle abrasive and the grinding disc change the removal mechanism and surface formation mechanism of the workpiece material. It should be pointed out that in some cases, grinding and polishing are difficult to distinguish, and the two terms are sometimes mixed.
