Typically performed on metal, wood, plastic, stone, or concrete, grinding is different from sanding in that it isn’t just about smoothing or blending a surface, but is meant to remove stock or shape a workpiece. Grinding can be achieved via a number of processes, including vibratory mass finishing, using hand tools such as right-angle grinders paired with grinding discs, or using bench-style grinding wheels.

While it is possible to produce a high luster by manually polishing a part using coated abrasives or buffing wheels, hand polishing can be expensive and inconsistent. Instead, mass finishing, particularly using high energy equipment or high frequency finishing systems, can yield a higher output of parts.

SurfacePrep supports a variety of grinding and polishing processes via a large selection of tools and equipment.
