Advantages & Features
The ST-38 is designed for the production of complex components and has a bar passage of 38mm. With three revolvers at 10 tool stations each (fixed or driven), diverse modular holders can be installed. The lower revolver also allows simultaneous processing of the main and counter spindles, which reduces the cycle time significantly.
