The Polishing Process utoledo.edu

2002-4-22  The Polishing Process Polishing is one of the oldest processing methods, first used on the making of stone implements. Polishing is one finishing loose abrasive process, used to generate surfaces with very high tolerances in geometry, surface integrity, and roughness characteristics. It is still one of the most important finishing methods.

Polishing

INTRODUCTION • Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with a significant specular reflection. • In some materials (such as metals, glasses, black or transparent stones) polishing is also able to reduce diffuse reflection to minimal values. 4/30/2015 2 3.

Buffing and Polishing— Looking to the Future

Now a single robot can process multiple pieces in one clamping operation, thus leading to a “happy medium” when compared with more-productive rotary or in-line systems. The key to a successful robot polishing or buffing system is in the integration of the robot itself to the polishing units. These units must have compliance.
