The ORBITEC 20 large part machining center provides the capability to create true turned surfaces on parts that are difficult, or too large, to rotate. The machine greatly reduces setup times and improves throughput for large, heavy and awkward workpieces such as those often found in the energy industry. As a cost-effective, innovative valve body production center the ORBITEC 20 can complete more than 75% of valve applications in one setup while maintaining high tolerances.

The machine's patented head-design technology allows it to perform a variety of operations, including the facing of flange surfaces, conical boring of taper holes, face milling and endmilling, in a single part setup.The machine's head allows the centerline of rotation to be moved for positioning the turning centerline where needed.
