Abstract

In order to optimize the operation of a rotary shaping machine-tool for workpieces clamped in a motor-driven chuck (5), the workpiece discharge channel (14) arranged in the chuck (5) and a motor drive are provided so that the chuck stops when the workpiece discharge channel (14) is in a downwards oriented vertical position.

Werkzeugmaschine zur rotativen Bearbeitung von in ein motorisch angetriebenes Futter eingespannten Werkstük- ken, wobei das einen radialen Kanal aufweisende Zwei-Bak- ken-Futter derart motorisch gesteuert ist, daß es zum Entladen in einer bestimmten Position stehenbleibt, dadurch gekennzeichnet, daß ein Teilabschnitt eines das ganze Zwei-Backen-Futter geradlinig kreuzenden Kanals einen Werkstück-Ausfallkanal ausbildet, welcher in der bestimmten Position vertikal abwärts gerichtet ist, zum radialen Ausfallen des Werkstückes nach Öffnen der Bak- ken. Machine tool for the rotary machining of workpieces clamped in a motor-driven chuck, the two-jaw chuck having a radial channel being motor-controlled in such a way that it remains in a certain position for unloading, characterized in that a partial section of a the entire two-jaw chuck crossing in a straight line forms a workpiece drop channel, which in the specific position is directed vertically downwards, for the radial failure of the workpiece after opening the jaws.
