What is Polishing?
Polishing is a processing technique that uses fine, hard particles called abrasive grains to gradually remove the surface of a material and create a smooth finish.
It allows for precise processing down to the micrometer level, resulting in a beautiful glossy finish that improves appearance and helps prevent rust and dirt.
When even higher smoothness is required, advanced polishing methods such as mirror polishing, precision polishing, and ultra-precision polishing are used.
