CNC crankshaft milling machine HELLER RFK 20-2-800

CNC crankshaft milling machine HELLER RFK 20-2-800 was built in 2001 by the German company Gebr. Heller Maschinenfabrik GmbH. The machine is designed for rough and finish milling of main bearings and/or lift bearings, including crankshaft sidewalls. The milling machine works in five axes with the feeds of 625 mm (W axis), 180 mm (U axis), 180 mm (X axis), 660 mm (Z axis) and 360° (C axis). The machine is controlled by the SIEMENS Sinumerik 840D CNC controller, processes a detail with a length of 800 mm and a diameter of 700 mm. The milling machine is characterized by a short workpiece replacement time, thanks to the freely accessible working space and a conveniently located clamping chuck. The total weight of the RFK 20-2-800 machine is 17 tons. We offer additional paid cutters for the machine for sale:
– IN11113502: 14265 EUR / 1 pcs.
– IIN11113500: 14330 EUR / 1 pcs.
