Rolling Mill Stands: Housing Rough and Finish Machining

Machining of each housing is performed on a 5-axes, latest generation CNC machine tool. Final geometry is checked by a CAM2 Laser Tracker Xi system to ensure that all working and backup surfaces are within the requested dimensional tolerances, flatness, parallelism, and squareness.
Rough machining can be performed up to more than 12 m width , above than 4.5 m height and maximum weight exceeding 120 ton on the machine tool rotating table. Depending on the rough steel cast geometry, more than 10 % of original weight can be removed during machining.
