ABSTRACT:
A dressing apparatus includes: a first body extending parallel to the axis of the cut-off wheel, the first body having a slider member slidable along the longitudinal axis of the first body, the slider member being urged by an urging member so as to be normally retained in an initial position thereof; a second body, slidably connected to the slider member, for movement in a direction perpendicular to both the cut-off wheel's axis and the first body's axis; a drive motor for rotating a pair of grinding wheels connected to the head member, the axes of the grinding wheels being perpendicular to a plane parallel to both the cut-off wheel's axis and the first body's axis, a line which is perpendicular to both of the axes of the grinding wheels being parallel to the first body's axis; and a drive mechanism, interposed between the first and second bodies, for moving the second body so that either of the grinding wheels is brought into contact with the peripheral cutting edge formed on the cut-off wheel to apply a dressing to the peripheral cutting edge. The drive mechanism includes: a cylinder actuator for moving the slider member from its initial position in either of the opposite directions; and a mechanism for causing the second body to move in a direction relative to the slider member simultaneously with the movement of the slider member from its initial position.
