4.3.2.2 Abrasion with Power Tools

Small handheld power tools or larger shop tools can speed the cleaning/roughening of surfaces. As in manual mechanical cleaning, a belt, rotary and orbital sanders may be used with abrasive media in a range of roughnesses; the operator must control the amount of material removed and, usually, one part is cleaned at a time.

Bristle blasting is abrasion using a rotary wire brush tool. The angle of the bristles and their acceleration as they are ‘snapped’ over a perpendicular bar give the bristle tips a speed and angle more like a particle-blasting treatment than a traditional rotary brush, leaving a pitted, clean surface.
