During MRO, helicopter blades are a challenge to sand because the paint thickness on rotor blades varies along the surface (especially considering the frequency of field repairs); because the substrate (and copper grid/ lightning protection) is susceptible to damage, and because the topcoat (particularly CARC paint used in some military applications) is hard enough to survive extreme operating conditions. Temple Allen’s solution focuses on finish quality (consistent scratch depth/pattern) and part protection - by holding the sander flat while applying even pressure to the workpiece, operators are able to dial in a desired contact force and thereby establish a predictable material removal rate which, among many advantages, allows different operators to generate the same high-quality results.
