Index R300
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-sysA new dimension in milling and turning RatioLine R300 tems, including 5-axis machining. Both heavy-duty roughing operations and highly accurate fine-turning 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.

- With up to 140 magazine stations, tools can be changed in only 6 sec chip-to-chip time on both spindles.
- The tool loading strip allows even more productivity gains by changing 8 tools during machining.
- Shortest change cycles; chip-to-chip time only 6 s.
- Simultaneous and independent loading of both milling spindles possible.
- High degree of functional reliability due to standard tool magazine with chain design.
- 70/140 tool stations (HSK-T63 mounting).
- Change up to 140 tools (HSK-T63) in 6 seconds chip-to-chip time – thereby shortening secondary processing times at both spindles
- Two full 5-axis systems in a turn-mill center
- Extensive automation options – tailored to the individual customer needs
- X travel ranges of up to 780 mm
