A grinding machine in which a first grinding wheel (12) is mounted on a wheelhead (20) adapted to be moved towards and away from a workpiece (10) for grinding same is provided, where a second grinding wheel (14) is mounted at one end of an arm (22), the other end of which is pivotally mounted to the wheelhead (20) about an axis parallel to the axis of rotation of the first grinding wheel (12), in which the first grinding wheel (12) is larger than the second grinding wheel (14), and means is provided for pivoting the arm from an upper parked position into a lower grinding position in which the second grinding wheel (14) engages a peripheral surface of the workpiece. Arms of different lengths allow variation in positioning of the second wheel relative to the workpiece and first wheel.
