Finishing and sizing sections are designed with interchangeable 4-roll stands. The tooling change has been conceived to minimise change-over time and operator involvement throughout the tube mill. Using existing forming concepts, Oto Mills has automated the tooling pick and set-up operations. In the finishing and sizing, the quick change-over does not occur by replacing the entire stand (as typically executed on smaller mills), but by swapping the assembly including rolls, shafts, bearing blocks and side rolls from the top of the stand. All driven stands are mounted to the mill base and universal joints are provided with an automated engagement/disengagement hydraulic system from the mill shafts allowing for the roll, bearing block, shaft, and side rolls (if provided) to be moved in and out of the stands, which are designed with an opening at the top to enable the change-over operation via crane. Jacks and absolute encoder for top shaft adjustment are part of the removable assembly. Adjustments on the roll, shaft and bearing block assembly are performed through electric gear motors and absolute encoders. The entire change-over operation is automatic, so that operators are simply involved in the lifting of the roll assembly in one motion.

The Oto 40616 ETC tube mill comes with a second set of shaft, bearing block and side roll assemblies to enable off-line roll change- over. The customer may also choose to purchase extra shafts and bearing blocks, which can be permanently assembled to the rolls for even faster roll replacement.
