Index Traub - Turn-mill center - Ratio Line, R series

With the R series, INDEX is setting the standard for a new generation of turning/ milling centers. Two motorized milling spindles perform machining in two independent sub-systems, including 5-axis machining. Both heavy-duty roughing operations and highly accurate fineturning operations can be performed simultaneously on the main spindle and counter spindle. This parallel use increases productivity significantly compared to conventional designs. New design solutions for optimum stiffness, thermal and dynamic stability, and vibration damping also provide for maximum machining quality.
