Abstract
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.
Claims6
A method of milling threads on a workpiece using a computer numerical controlled (CNC) lathe machine, the method comprising:
- mounting a tool platform on the CNC lathe machine, the tool platform operable to perform a turning operation by positioning a static tool against a surface of the workpiece;
- performing the turning operation by rotating the workpiece with the static tool against the surface of the workpiece, which workpiece is supported in a work holder;
- rotating a thread milling tool supported in a milling tool holder, the milling tool holder fixedly secured to the tool platform;
- and
- milling threads in the workpiece in a milling operation using the thread milling tool while rotating the workpiece supported in the work holder.
