Abstract:
A constant force finishing system used to finish a surface of a workpiece includes at least a first movement device arranged to apply a first movement to a finishing tool, the first movement having a range of distance D1. The finishing system also includes a constant force device (CFD) in mechanical communication with the finishing tool, the CFD arranged to apply a second movement in conjunction with the first movement to the finishing tool, the second movement having a range of Δ1, where D1>>Δ1.
