MC with movable table / GB series

Double Gantry Boring Machines

Product description

Portal milling machines from GMW with moving table are particularly characterised by their high load capacity when absorbing machining forces. In particular, these machines are designed for the high loads during the machining of large parts. With modern milling units, this design permits high cutting speeds and multi-axis machining with large workpiece weights and dimensions.
