Abstract: A work rest blade assembly for a centerless grinder that provides multiple wear surfaces on which a work piece may be supported. The work rest blade assembly includes a generally cylindrical work rest bar splined at opposite ends and clamped to a crowned support plate in such a manner that the bar is flexed from end to end to impose a bending moment thereon and is twisted in opposite directions at opposite ends so as to impose a rotary moment on the bar to thus rigidify it.

Abstract: Method and apparatus for automatically dressing a regulating wheel to the required curvature for a centerless grinding operation. A dressing wheel is mounted for rotation about an axis which is inclined to a reference axis. The regulating wheel is mounted on a gimbal assembly which permits the axis of that wheel to be oriented as desired with respect to the axis of the dressing wheel, and the gimbal assembly is mounted on a carriage which is movable in directions parallel and normal to the reference axis. With the axis of the regulating wheel positioned as desired and the wheels in peripheral engagement, the wheels are rotated and moved relative to each other in a direction parallel to the reference axis to dress the regulating wheel. The angle between the axis of the dressing wheel and the reference axis is made to correspond to the angle at which the axis of the regulating wheel is inclined to feed workpieces past the grinding wheel in a centerless grinder.

Abstract: A grinding wheel functions both as an abrasive wheel and as a blower for removing dust and cooling the workpiece and wheel. The wheel has passageways through which air and dust are drawn from one axially facing side of the wheel to the other as the wheel rotates. A shroud partly encloses the wheel, and means is provided for catching dust from the workpiece and holding the dust in position to be drawn through the wheel by air passing therethrough. An exhaust duct is provided for carrying the dust and air passing through the wheel away from the wheel.
