Peripheral speed
The linear speed of a point on the circumference of a rotating disc, determined by rotational speed and effective diameter.
Restoration processes and safety
Contact pressure
The normal force applied through a tool divided by the effective contact area at the glass surface.
Backing pad
The interface that connects an abrasive disc or polishing pad to the powered tool and supports it during rotation.
Pad conditioning
A controlled preparation or maintenance action intended to restore a polishing pad’s usable surface texture, fiber exposure, cleanliness, or slurry distribution.
Abrasive disc
A flexible or rigid circular product carrying fixed abrasive or an abrasive structure for powered surface treatment.
Polishing pad
A compliant contact tool that carries and distributes polishing compound over the glass surface.
Polishing compound
A formulated material applied with a polishing tool to refine glass, commonly containing fine particles in a liquid or paste with additional ingredients.
Cerium oxide slurry
A suspension containing cerium-oxide-based polishing particles in water or another specified liquid carrier.
Abrasive particle size and grit designation
The measured particle-size distribution of an abrasive and the named grading system used to designate it.
Loose abrasive
Abrasive particles supplied free in a powder, paste, suspension, or slurry rather than fixed to a disc, belt, or wheel.
