A process to generate a reflective surface. Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process.". The pad is softer than ...

Surface finish is a term that refers to the process used to alter a metal's surface by adding, removing or reshaping. The goal is to protect the metal and improve the aesthetic side. The result depends on the metal finishing method. Often, there are a few different ways to achieve the same or similar results.

Knowing what you're trying to accomplish is the first step in choosing the right abrasive product. Completing rough grinding after a deburring operation requires a different process and products than does blending or finishing, for example. A common pitfall in surface finishing is using the same wheel no matter the job.

All the grinding grains in contact with the workpiece create a machining pattern by means of overlaying individual sinusoidal lines that cross each other at a particular angle. This generates a specific, defined pattern of grooves and plateaux, which, in turn, results in the particular advantages of the superfinishing process.
