Grinding and Polishing GRINDING removes saw marks and levels and cleans the specimen surface. Polishing removes the artifacts of grinding but very little stock. Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or ...

Unlike cylindrical grinding, centreless grinding is a form of grinding where there are no centres holding the object in place. Instead, it uses a regulating wheel positioned on the opposite side of the object to the grinding wheel. Concentricity is not critical. Combined with centreless polishing surface finishes of < Ra can be achieved.

The goal of Fine Grinding is to reduce damage and surface roughness of samples to a degree that is suitable for polishing. The choice of surface depends on the physical characteristics of the material to be ground and is critical. Rigidly fixed abrasives gives a flatter preparation result than when using surfaces with a shock absorbing backing.
