Abstract: The machine comprises a retainer member (28) for a saw blade (10) to be plugged on as well as two machining stations located diametrically opposite each other with respect to the retainer member (28). A grinding device (38, 58) each is disposed at the two machining stations. The grinding devices (38, 58) are controlled such that they act simultaneously on a tooth (12, 16) each of the saw blade (10). Furthermore, a clamping device (70) each is disposed at the two stations, and these clamping devices are controlled such that they simultaneously clamp the saw blade (10), respectively, before the grinding devices (38, 38) engage the saw blade (10).

Abstract: A movable clamping jaw (14) cooperating with a stationary clamping jaw (12) is carried by a support member (20) which is guided for displacement at a bracket (26) by a flat guide means (30) to cause slightly arcuate movement, deviating only a little from the plane of the saw blade, of the movable clamping jaw (14) away from the stationary clamping jaw (12). The support member is adapted to be clamped to the bracket (26) and, in addition, is connected to the bracket (26) by a four-joint arrangement (22). The clamping device needs only little room for opening and closing.
