Abstract: The invention refers to a length measuring device, with which a working length of a work piece may be determined for milling machines and sawing machines. The measuring device comprises one unit with a movable buffer which is laid out and secured parallel to the table on a level and vertical to the cutting tool of the machine. An electrical sensor device operable relative to an electrical ruler is synchronized to move with the buffer and the sensor device is electrically connected with an indicator to provide a read out of the measurement.

Abstract: A chucking device, in particular a vise having two chuck jaws at least one of which is embodied in two parts in the longitudinal direction. A rail guide is present between the two parts, and one of the parts, serving as a pedestal part is joined to the supporting elements of the chucking device, while the other part can be removed and replaced via the rail guide, and the rail guide simultaneously acts as a means of coupling the two parts in the direction in which the chucking force is applied.
