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

BRAND NEW KRAFT FB SERIES FACING LATHE — FOR LARGE FACEPLATE WORKPIECES UP TO 2 TONS (SUSPENDED)

The KRAFT FB series provides economical machining of large, flat workpieces such as brake discs, flanges, wheels, bearing rings, or drum components. Four machine sizes with turning diameters from 1,500 to 3,000 mm and suspended workpiece capacity up to 2 tons cover single parts and small to medium batch production.

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