A tooling assembly for a lathe machine includes a tool platform configured to be mounted on the lathe machine, a milling tool holder fixedly secured to the tool platform and workable to releasably secure a thread milling tool therein, and a milling tool drive. The milling tool drive is operatively connected to the milling tool holder and operable to rotate the milling tool holder independently of a work holder to mill threads on the workpiece when a pipe thread milling tool is secured in the milling tool holder. Computer numerical control threading lathes and methods of milling threads in tubular workpieces are also described.

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.

A system for simultaneously forming multiple flutes in a carbide rotary cutting tool includes a chuck adapted to grasp a green rod member and selectively rotate the green rod member about, and translate the green rod member along, a first axis. The system further includes a mechanism adapted to simultaneously machine multiple flutes in the green rod member as the green rod member is rotated about, and translated along, the first axis.
