Which technique uses a moving belt to abrade and smooth a surface before finishing?

• A. Linishing
• B. Polishing
• C. Grinding
• D. Surfacing

Answer: (A)

This question targets understanding of belt-based finishing. Linishing uses a moving abrasive belt mounted on a linisher or belt sander to progressively abrade and smooth the surface, removing small irregularities and creating a uniform finish that’s ready for final polishing or coating. The key idea is the belt’s continuous motion across the workpiece, which gives controlled material removal and a finer surface than coarse grinding. Grinding relies on a rotating wheel for material removal, not a belt; polishing uses very fine abrasives to create a glossy finish after roughing; surfacing is a broader term for flattening or preparing a surface and isn’t specifically tied to a belt-driven process.
