BRAND NEW KRAFT FB-SERIES VERTICAL TURNING LATHE — FOR LARGE FACEPLATE WORKPIECES UP TO 2 T SUSPENDED

The KRAFT FB-Series is designed for the economic machining of large, flat components such as brake discs, flanges, wheels, bearing rings, or drum parts. Available in four sizes with turning diameters from 1,500 to 3,000 mm and workpiece weights up to 2 t (suspended), they are perfectly suited for single-part and small to medium series production.

Available as conventional or CNC version (Siemens, Fanuc or Fagor), with or without tailstock, longitudinal or cross-bed configuration.
