  • Patent number: 4872244
    Abstract: Turret comprising a turret body and a turret head which is rotatable about an indexing axis relative to the turret body and in which several spindles are rotatably mounted. By moving away from the turret body in the direction of the indexing axis, the turret head is unlocked and made rotatable about the indexing axis. To enable one only or several selected spindles to be driven at a time and the remaining spindles to be locked against unintentional rotation, a drive shaft mounted in the turret body in spaced relation to the central indexing axis is released from the previously driven spindle when the turret head moves away from the turret body, and, in addition, each spindle has an associated locking mechanism which is arranged in the turret head and which is only released in the case of the spindle to be driven at that particular time when the turret head is locked on the turret body.

  • Patent number: 4818925
    Abstract: Device for setting the working point of a tool with respect to a reference point in an NC machine tool with a tool slide system and a path measuring system for the tool slide motion which is connected to a machine control system, and with a control sensor for transmitting a correction signal to the machine control system. The control sensor can be brought to the reference point, up to and over which the tool point can be moved by program control, starting from a starting point of the tool slide. The starting point of the tool slide and the reference point are spaced at a specified distance from one another and distances of the tool point from the starting point of the tool slide can be balanced by the machine control system against reference distances which can be evaluated by the machine control system on the basis of the correction signal and also on the basis of path measurement signals of the path measuring system.
