The BM300 is the only mandrel-free tube bending machine able to bend tubes both to the left and to the right, thanks to the reversible die holder of our own design and patent. Its innovative design allows tubes to be bent up to 273 mm diameter and 18,26 mm wall thickness. With a maximum centreline radius of 1700 mm, it delivers the highest performance to be expected from a machine of this size. The bending rotation speed (max.
0,4 rpm) is controlled by a dedicated inverter.
