Clark Machine was recently contracted by a steel mill for the repair of a series of large mill rolls used in their steel processing operation. Clark specified a multi-step procedure for the reconstruction of the mill rolls. Material was added using MIG, FCAW, SMAW welding, followed by milling to required dimensions and additional machining to restore journals and keyways. The rolls featured dimensions of 16″ in diameter and 186″ in length, and were machined using our engine lathes, and a horizontal boring mill. The entire process was subject to our own stringent quality measures which included weld and dimensional inspections.
