Abrégé

Disclosed is a method for manufacturing a stator for an eccentric screw motor where at least two milling heads are used for machining the inner wall of the stator tube, wherein, at the start of the machining, one of the milling heads is brought to a predetermined position near the stator with respect to the end of the stator tube, the milling head is fed into the tube interior along its linear axis from this predetermined position, and a thread is machined until the milling head reaches at least the longitudinal center of the stator tube or exceeds a predetermined value, and the second milling head starts its machining of the inner wall surface of the stator tube at this point, wherein the milling head is moved along its linear axis and rotated about its rotary axis until the milling head reaches the centre of the stator tube.
