Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.

Introduction to Buffing
Introduction to Buffing "Buffing" is the process used to shine metal, wood, or composites using a cloth wheel impregnated with cutting compounds or rouges. The cloth buff "holds" or "carries" the compound, while the compound does the cutting. The industry refers to "polishing" as the process, which uses abrasive belt finishing.

A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process. In this study ...
