  • Publication number: 20150308753
    Abstract: A method for producing a multilayered pipe line, in particular for transporting refrigerant in an air-conditioning system. First, an endless inner layer made of stainless steel having a layer thickness of at most 1 mm, preferably at most 0.5 mm, is provided, which constitutes the inside layer of the pipe line. Then, the endless inner layer is covered, by means of an extrusion process, with a plastic layer that preferably has a layer thickness of at most 7 mm, in particular at most 5 mm.

  • Patent number: 7513027
    Abstract: A process for machining a blank from all directions with a machine tool, such as a milling machine, involves the machining from all directions being based on a three-dimensional template. In a first step, the three-dimensional form and, if need be, also the surface finish of the three-dimensional template may be automatically measured, and the associated data may be saved. In a second step, a blank may be held by at least one clamping adapter and a first region is brought into its final, ready to use partial form by the machine tool or the milling machine using said data for numerical control. In a third step, the partially machined blank may be held by at least one clamping adapter in the first, finally machined region and the remaining region may be brought into its final, ready to use overall form by the same machine tool or milling machine.
