Polishing is a process by which material is precisely removed from a workpiece to produce a desired dimension, surface finish, or shape.
Polishing techniques are beneficial due to the precision and control with which material can be removed.
There is a wide selection of abrasives to choose from when selecting a lapping and polishing process. Selecting an abrasive is dependent upon the specimen hardness, desired surface finish, desired removal rate, lifetime, and price.
The process of polishing materials has been applied to a wide range of materials and applications, ranging from metals, glasses, optics, semiconductors, and ceramics.
