What to Know About Sanding
Sanding tools use abrasive sheets, discs, belts, sleeves, or drums to remove small amounts of material. Machine type affects scratch pattern, removal rate, dust collection, and access to corners or curves.
Working principleAbrasive grains cut fibers or finish as the tool moves. Coarser grits remove defects; finer grits refine the scratch pattern. Dust extraction keeps the abrasive cutting and reduces airborne dust.
Setup
- Start with the least aggressive grit that removes the defect.
- Connect dust collection where possible.
- Keep the sander moving before and after contacting the work.
- Mark the surface lightly with pencil to track progress.
