Abstract: The invention relates to a sawing machine for cutting or separating workpieces (1), in particular a sliding saw, for sawing rolled products such as profiled bars (1) or round bars on the output side of a rolling train, comprising at least one rotating saw blade (2) with saw teeth (SZ), also comprising a transporting device (3) for feeding the workpieces (1) to the sawing machine, also comprising a drive (4) for a sawing slide (5) for advancing the sawing machine while cutting or separating the workpiece (1) in a preselectable cutting plane (SE) by a predetermined advancing increment (H) and for returning the sawing machine after the cutting or separating operation has been performed, and comprising a saw-blade grinding device (7), which can be placed at least with the end face against the saw blade (2) and is intended for at least circumferentially working the saw teeth (SZ). The saw-blade grinding device (7) has at least one braking unit (14, 15).

Abstract: An apparatus for the straightening (dressing or peening) of relatively large circular-sawblade blanks, especially for hot-sawing circular saw blanks, comprises a stand for a forging hammer which is provided with a pneumatic peening hammer directed upon a working point and a support which is linearly shiftable relative to the hammer. The hammer is vertically reciprocatable and the translation direction of the support is horizontal and perpendicular to the axis of the hammer. The support comprises linearly-shiftable carriage provided with a table which can be rotated about a vertical axis through at least 180.degree. and the peening portion of the hammer is also rotatable about a vertical axis through at least 90.degree..
