Last month between the holidays, Global Alignment machined and grinded two steam rollers with a length of 3000 mm and a diameter of 1500 mm. The steam rollers were damaged and should be machined straight and concentric to the axis of the shaft. The roughness of the steam rolls had to be ground to within the maker’s tolerance of 0.4 – 0.8 and the runout should not exceed 0.03 mm.
