Abstract

A polisher is supported on either a frame/arm arrangement or on a vehicle which is guided by track, and is arranged to be energized to polish a predetermined surface of an annular flange or the like, when relative movement is sensed between the polishing element and the surface to be polished. The polishing arrangement can be motor driven so that the polisher can be left to polish the surface in the absence of an operator.
