Abstract

The invention concerns a belt grinding machine or finisher, adapted to grind a flat or curved surface. The belt is driven and endless and passes over a conveyor on which workpieces each having a face to be ground, are located. The belt runs over a flexible beam which can be bent by one or more of a plurality of piston and cylinder units some of which are fixed to and some mounted displaceably on the frame of the machine, each cylinder having a feeler-actuator which during the passage of a workpiece past the belt, comes into contact with the surface to be ground, or a template, and follows the curvature thereof. Each feeler operates a valve to admit pressure fluid to or drain it from its cylinder so that the various cylinder actuations cause the beam and hence the belt to follow a path the curvature of which is that desired on the workpiece surface.
