Report on the manufacturing of crankshafts for 6-cylinder engines for heavy-duty trucks in the Forge of Casanova Campdevanol. Detailed explanation of the manufacturing process and the machinery (automatic copy router, probe) used to create the model of the crankshaft mould. The voice-over emphasizes this is the first time in Spain that 150-kilogram crankshafts are made following the process of stamping and checking. Images of the various stages of manufacture: steel entering the furnace and stamping by hammering, cutting off burrs with a hydraulic press, mould and second stamping, mould and cutting off burrs again, finishing touches and, lastly, normalizing and collection, inspection and correction of the burr.
