摘要： Described is a double-turret tool holder for a lathe, the tool holder having two turret discs (16, 18) mounted coaxially to each other and connected so that they rotate in unison. The two discs can be continuously displaced relative to each other along their longitudinal axis by a control drive (44) and can be clamped at any required relative longitudinal positions. In order to be able to machine workpieces (14) on both sides with rotational tools, e.g. grinding wheels (28, 30), longitudinally aligned tool-clamping devices (24, 26) are rotatably mounted at at least one point on the circumference of the turret discs (16, 18), the tool-clamping devices being coupled to each other by a drive shaft (46) passing through the turret discs.

摘要： The multiple-spindle lathe described has at least two parallel-acting workpiece spindle units (18, 20) mounted to move in the x and z direction. The spindle units operate in conjunction with fixed workpiece carriers (22, 24) and themselves convey the workpieces to and from a workpiece-turning device (30) so that there is no need for an automatic conveyor to feed the workpieces between the two spindle units (18, 20).

摘要： Ce tour automatique multibroche possède au moins deux ensembles broches porte-pièces (18, 20) se déplaçant dans les sens X et Z. Ces ensembles, coopèrent avec des porte-outils fixes (22, 24) et assurent eux-mêmes le transport vers et depuis un dispositif de retournement (30), de sorte qu'aucun dispositif de transport n'est nécessaire entre les deux ensembles broches porte-pièces (18, 20) pour le transfert automatique des pièces.

摘要： A lathe has two workpiece spindles (28, 30) rotatively mounted each in a headstock (24, 26) and movable therewith in the direction of and transversely to the axis of the spindle. The workpiece clamping means of the spindles (28, 30) face each other. Tool holders (32, 34) are fixedly mounted at the front side of the lathe. In a front working area, the workpieces (46) are shaped exclusively by the displacement of the spindles (28, 30) in the X and Z directions, in cooperation with the tool holders (32, 34). In a transfer position located further back on the guides (12, 14), they are then directly transferred, i.e. without any reversing means, from a spindle (28) to the other (30). Still further back, they are taken up by a conveyor arrangement (44) or delivered to a conveyor arrangement (50).
