Grinding v. Polishing

Both grinding and polishing occur in the latter stages of production for fixing blemishes and providing final cosmetic finishes


    • A abrasive process that wears off tiny chips of material to create very fine finishes and accurate dimensions
    • Removes saw marks and levels surfaces
    • Typically uses sanding belts and orbital sanders
    • Better suited to hard materials and for making shallow cuts
    • Also known as abrasive cutting


    • A finishing process for smoothing flat metallic surfaces and creating reflective surfaces; can be sent directly to chroming
    • Enhances aesthetic appeal and removes oxidation
    • Uses progressive sanding belt and buffing wheels
    • Usually follows grinding processes–can remove scratches and damage from previous grinding
