horizontal2-axisflatbed

Product description
The Forceturn 800.50 series is a heavy-duty CNC lathe platform designed for machining large, heavy workpieces up to 5100 mm. The rigid flat-bed construction and oversized hardened guides ensure high static and dynamic stiffness for accurate turning operations. The Fagor control provides intuitive cycle programming and teach-in functions; two electronic handwheels permit manual-style setup and fine positioning. Configurable options allow adaptation for maintenance shops and single-piece production.
