<p>The method involves machining a stator segment (1) provided in an initial condition by a material erosive linear cutting unit for producing a helical segment inner surface (2). The cutting unit is moved along closed outer edges (3, 4) such that the edges run on the inner surface. The cutting unit is aligned such that a gradient of the cutting unit lies on the inner surface and formed as a jet e.g. water jet, laser jet or plasma jet or a wire e.g. spark erosion wire or fuse wire. The stator segment is made of metal i.e. aluminum, ceramic or cross-linked thermoplastic polymer. An independent claim is also included for a stator segment for a stator constructed in segments of an eccentric screw pump or eccentric screw motor.</p> |
