ABSTRACT:
A grinding machine is provided wherein a pair of wheel slides are disposed respectively at both sides of a work support to be movable toward and away from the work table in a first direction. The wheel slides respectively carry turrets thereon in such a manner that each of the turrets is rotationally indexed about and slidable along an axis thereof extending in a second direction perpendicular to the first direction. Each of the turrets carries a plurality of grinding wheels which are rotatable about respective axes extending in the second direction, and when rotationally indexed selectively presents the grinding wheels to a machining station. The position of a selected one of the grinding wheels relative to a workpiece on the work support is adjusted in the first direction through the movement of each wheel slide and in the second direction through the movement of each turrets. Upon completion of the position adjustments, the work support is moved in a third direction perpendicular to said first and second directions, so that the workpiece is ground as it passes between a pair of grinding wheels having been presented to the machining station.
