Advantages & Features
The ST-20 is designed for the production of complex components requiring many tools. With three revolvers at 8 tool stations each (firmly or powered) various holders can be installed modularly. The lower revolver also allows simultaneous machining of the main and counter spindles, which significantly reduces the cycle time.
