The mobility of the tool arrangement allows a machining towards the centre of the workpiece holder. The mobility of the tool arrangement on the other slide track (24) is limited from a position which is so spaced from the centre of the workpiece holder (12) that it prevents a contact of the tool arrangements on the slide tracks (18, 27).</p> |
