Universal models dedicated to medium sized pieces (diameters from 20 to 180 mm). The configuration can reach 6 fixed spindles, with 6 controlled axes (one “X” and one “Z” axis for each head, plus those of the electromechanical clamping system); of great power and particularly suitable for working without supervision. Possible processes: milling, centering, drilling, tapping, chamfering and collar with dedicated tools.
