The core components of the compact machining center are two roll grinders of the type WS 250 MonolithTM. It is loaded via a traversing workpiece pallet which can be parked within and outside of the fully automated area. While the workpieces of one pallet are machined, the other pallet is loaded and unloaded. Thus, non-productive time is reduced and the capacity is increased – valuable production time of the grinders is wasted no longer.
