Special steels require more and more frequently to be straightened during the production process and this is the reason why a famous steel plant decided this important order for a 600 kN machine for automatic straightening of 10 meter long bars. On this machine the automatic system for workpiece identification is particularly noteworthy, this system also allows small batches of parts to be processed with random feeding of accumulation magazine. This way the machine can automatically perform all the required set-up operations, leaving the operator free for other production activities.
