摘要： A method for producing a thread on at least one end of at least one metal tube (3) by machining the metal tube (3) in at least one CNC-controlled machine tool (2) comprises an optical measurement of the thread during the thread-cutting process and/or following the thread-cutting process, and the electronic detection and evaluation of the measurement data of the thread profile and/or of a sealing lip (6) of the thread, and the derivation of control commands for controlling the machine tool (2) from the measurement data with use of at least one closed-loop control unit coupled to the machine tool (2). A corresponding thread-cutting facility is also disclosed.

摘要： A method and a device can be used for optically measuring a thread on an end of a metal pipe by at least one measuring head which is fastened to a manipulator. The measuring head is preferably freely positionable in relation to the metal pipe and has at least one optical measuring path for measuring the thread and at least one position detector. The method includes at least the following method steps: A) providing the metal pipe in a measurement position; B) determining the spatial position of a longitudinal axis of the metal pipe by means of the at least one position detector before and/or while the measuring head is positioned in a measurement position; C) aligning the measuring head parallel to the longitudinal axis of the metal pipe before and/or while the measuring head is positioned in the measurement position; and D) carrying out the optical thread measurement.

摘要： A cross-rolling mill for rolling a block over a mandrel forms a hollow block. It includes a plurality of working rollers, each of which exerts a substantially radially aligned rolling force onto the block. The working rollers are supported in a roll stand, and the gap between the working rollers and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block can be modified. Hydraulic actuators, preferably hydraulic capsules, are provided in order to modify the rolling gap and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block.
