ABSTRACT:
A grinding machine has a base and a pair of work support bars journalled within the base. A table is journalled with the support bars in such fashion that it is axially movable along the parallel spaced bars and pivotable around one bar central axis while the other bar is radially displaced relative to the base. A pair of ramp surfaces having ramp planes disposed transversely to the pivot axis of the table are provided on the radially movable bar, such that a wedge feed is accomplished by relatively moving a powered wedging device along the ramp plane to thus radially move the movable bar, thereby causing table feed movement with respect to the base. A work support head stock is preferably carried on the base, and a wheelhead having a rotable grinding wheel is carried on the table, so that pivotal movement of the table causes relative feed movement of the grinding wheel with respect to a supported workpiece.
