Abstract: The invention relates to a machine having a base (300) and at least one work station (306) that has a module (50) for electrochemically machining a workpiece (51). The module comprises: a frame (54); and an electrode arrangement, having at least one electrode (60, 160), which is mechanically connected to the frame, and a drive (56, 156) for moving this electrode, which drive is attached to the frame; a workpiece holder (310, 311) for separably attaching the workpiece; and a positioning device (312, 313) for displacing the workpiece holder and the module relative to each other.

Abstract: An apparatus for the heat treatment of integral rotors of gas turbines is disclosed. The apparatus includes a closable working space which can be evacuated or filled with inert gas, a heat source, a distance-measuring instrument, and a pyrometer. A method for diminishing and/or for eliminating internal stresses which are introduced into a component through welding is also disclosed.
