Star SB-12R Type G

The SB-12R Type G offers impressive machining versatility within a compact footprint. The SB series main spindle platen includes six turning tools, two fixed high-speed ER11 spindles for cross working plus a further three modular cross power driven stations that accept a variety of cartridge attachments.

The flexibility of the SB-12R Type G is further enhanced by its ability to switch between guide bush mode (Swiss type) and non-guide bush mode.

The fully independent sub-spindle with C axis control coupled with driven tool capability across all four back working stations further enhances the machining capability of the SB series.
