Head Turning Lathe KRAFT FB-15/20/25/30, brand new · 1500–3000 mm faceplate · CNC or conventional

BRAND NEW HEAD TURNING LATHE KRAFT FB SERIES — FOR LARGE FACEPLATE WORKPIECES, UP TO 2 T FLYING

The KRAFT FB Series is designed for efficient machining of large, flat workpieces such as brake discs, flanges, wheels, bearing rings, or drum components. Four model sizes with turning diameters from 1,500 to 3,000 mm and workpiece weights up to 2 t (unsupported) cover single unit and medium-sized batch production.

Available as conventional or CNC variants (Siemens, Fanuc or Fagor), with or without tailstock, bed orientation longitudinal or crosswise.
