Star CNC SB-16R
Category: Star CNC


The SB-16R Type G offers impressive machining versatility within a compact footprint. The SB series main spindle platen includes six turning tools, two fixed high-speed ER16 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-16RG 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.



  • Maximum machining diameter 16mm
  • 4 types of tool posts available from which to select the tooling layout most suited to the required machining applications
  • Flexible tooling layouts allow for endless variations of complex machining
  • Flexible tooling layouts include the ability to combine the selection of tool post and cartridge unit
  • Maximum tooling variations yield performance that meets manufacturing needs across multiple industries
