Important for the future buyer: The machine is currently out of operation as the bearings and drive belts need to be replaced. The milling machine is basically operational, but both axes are no longer running exactly parallel – normal wear and tear for machines of this type over time. These works should be carried out once the machine is at the buyer’s location. Transport and installation can be arranged by Buth Graviersysteme.
