Abstract: A machine saw comprises a machine frame, a slotted flat plate rotatable about a vertical axis and serving to receive a workpiece to be sawn, a motor-driven circular saw blade which is rotatable about a horizontal axis of rotation and is adapted to be passed upwards through the slot in the rotatable plate from beneath during sawing, a clamping bridge which is fixed in relation to the frame and spans the rotatable plate and a clamping device mounted by the bridge for clamping a workpiece on the rotatable plate. Part of the clamping device is formed by a clamping jaw movable vertically upwards and downwards and adapted to be set down onto the workpiece, this clamping jaw being rotatable about the axis of rotation of the rotatable plate and displaceable at right angles to this axis of rotation in a sliding guide means.

Abstract: The invention relates to a circular saw machine having a machine frame, a workpiece support, a rotatingly driven circular saw blade and a clamping device for clamping workpieces on the workpiece support; the clamping device is displaceable and clampable on the machine frame and relative to the circular saw blade in a groove and by means of a sliding member engaging in this groove. The sliding member is hereby designed to be clampable in the groove by means of an eccentric so that the clamping device of such a machine may be adjusted and locked in position in a simple manner.
