PRODUCTION FACILITIES

Stelmi equipment machines the tube horizontally; the tube turns and the tool translates, carried at one end of the boring bar. Rotation and translation may be varied continuously. Machining the tube horizontally means an easier control of the tube itself from both sides and an easier positioning for long tubes. The machining operation is fully automated.
