SB-12R Type G

Star CNC SB-12R Type G

Popular 12mm machine for manufacturing small diameter components for use in a variety of industries

  • Modular machine design flexibility greatly benefits the machining of small diameter parts
  • Ability to switch between Guide Bush and Non Guide-Bush Modes improves machining efficiency
  • Main spindle with 17 tool positions extends manufacturing possibilities
  • Fully independent sub-spindle with driven tool capability increases the amount of overlapped operations that can be carried out
