We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

What is the process of polishing?

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.

What is the principle of polishing?

Polishing is a processing technique that removes irregularities on the surface of a product using abrasive grains. Since it can be adjusted in um (micrometer) and micron units, it is often used in the final process of product processing.

What is the science behind polishing?

At a microscopic level, even seemingly smooth surfaces have peaks and valleys. The polishing process systematically removes these irregularities by: Material Removal - Abrasive particles in the polishing compound scratch the surface, removing minute amounts of material.

What is the mechanics of polishing?

Mechanical grinding and polishing consists of removing material from a specimen with increasingly fine grit grinding paper or polishing compounds (typically performed on a rotating wheel platen).

Which two types of polishing methods are used for specimen preparation?

Specimen surfaces can be polished by diamond suspensions of successively finer particle sizes. Those particles can be in sub-micro or nano sizes. For example, Sakulich et al. [69] used a series of graded sized particles from 9 m to 0.05 m for fine polishing.

What are the 3 stages of polishing?

The first is usually very aggressive, typically wet sanding or a heavy abrasive with a heavy cut pad, like M105 and a MF cut pad. 2nd stage is to refine the heavy cut, so something like a low abrasion compound or a more aggressive polish, and the 3rd stage being fine polish.
