Abstract: A press brake having bed and ram members whose tool-holding faces, edges and surfaces need reconditioning due to wear, and a portable milling machine adapted to be fixed to the press brake to mill and thus recondition the faces, edges and surfaces. An improved milling machine comprising an elongated carriage-support assembly supported on the bed and separated from the ram, a milling-head assembly having a carriage and a set of cutters seated on the carriage with the milling-head assembly being mounted on the carriage-support assembly, and a carriage-feed drive assembly coupled to the carriage to drive the milling-head assembly the length of the carriage-support assembly with the cutters selectively engaging any faces, edges and surfaces needing reconditioning.
