With two center-drive-heads for simultaneous end machining of shafts with a length up to max. 1.600 mm or with chuck construction for 4-axis turning. The product range V 300 is multifunctional and convenience through short loading and unloading times as well as simultaneous machining with two turrets. The V 300 series is particularly suitable with center-drive-heads if only both ends need to be machined and so the complete machining can be carried out in one clamping.
