The range of big-sized vertical lathes VERTIGO represents the new reference point of the sector. FPT decade-long planning and technological experience in manufacturing big-sized hydrostatic borig machines , finds a new implementation in the turning, milling and grinding technology of big mechanical components. The result is a new family of machines offering solutions available for the first time on the market: • Full hydrostatic movement of all axes (included the vertical movement of the beam W) with “active” oil cooling system; • Clever hydrostatic thrust-bearing “tilter” for the table bearing and rotation with automatic unbalancing control of the loads to be machined, with adjustment data self-learning (Patent Int. Pend.); • “Load control” device allowing constant maintenance of the geometry and stiffness of the table according to the loading condition changes, by means of a hydrostatic system with “active” preload (Patent Int. Pend.); • Turning spindle movement transmission device with hybrid gearbox (planetary+parallel) and high torque and liquid-cooled built-in motor; • Dual Drive type, dedicated high stiff transmission system of C axis with complete backlash compensation and with very high bidirectional dynamics (deriving from the big-sized table of FPT boring machines); • Direct Drive kinematic system of the milling spindle. This solution manufactured for years by FPT for its boring machines, provides an in-axis power transmission to the spindle, without mechanical gear systems, through high torque liquid-cooled built-in motor.
