ABSTRACT:
A radial belt grinder having a drive wheel and a camber adjustable idler wheel coupled by a housing assembly. The housing assembly is rotatably supported on a machine radial groove by four shoulder bolts which also function to attach a C-framed motor to the base ring plate. A closed loop abrasive belt is transported about the wheels to accomplish multiple position platen and contour wheel grinding. An anti-recoil control mechanism facilitates belt exchanges and limits pressure recoil when the idler wheel is used in tilt angle, contour wheel grinding. A universal work rest arm, centrally supported at the rear of the housing assembly, provides the structure to adjustably support the work piece in infinite radial work positions through 180 degrees. A quick set friction lock functions to secure the rotatable housing at a selected radial angle. The work rest and all guards are reversable to accommodate left or right hand machine operations.
