Abstract
A machine for working on saws has a mounting (20) for a saw blade (10), an advance mechanism (30) for advancing the saw blade (10) stepwise through one or more tooth spacings, and a machining device (40) which, after each completed advance, carries out at least one working stroke on a tooth of the saw blade (10). A spacing gauge (58) on a disc (56) is connected with the saw blade (10) for common advance motion and acts together with a signaler (62) which transmits signals in response to the advance of the saw blade (10) to a control circuit (60). Said control circuit (60) permits a working stroke of the machining device (40) only when the intended advance of the saw blade (10) has taken place. Thus, the danger of the saw blade (10) being damaged as a result of an erroneous advance from the machining device (40), or of the machining device (40) itself being damaged, is avoided.
