The flexible one


The new STAR SP-23 is the first automatic lathe able to machine diameters up to 23 mm. The machine impresses with 8 turning tools and 7 power-driven cross-machining stations with 5 of these being exchangeable. The proven power-driven tools of the SR class can also be used. Using the new HIGH TORQUE option for the main and sub spindles, it is also possible to perform the most difficult rough and drilling operations.



  • CNC control FANUC series 0i-TF Plus, control system with handle
  • C axis control as standard on main and sub spindles
  • fully independent backworking with 4 stations
  • convertible from sliding headstock to fixed headstock lathe
  • movable control panel

Your advantages

with star Micronics

  • Training
    STAR Micronics GmbH offers special training sessions for machine operators. You as customer can decide whether to have the training in our company or on your premises. The training is naturally exclusively for your personnel and specifically designed for your range of parts.
  • High pressure unit
    The machine can be retrofitted with high pressure units from 50 to 300 bar. In addition, other developments are available to you, such as programmable pressure control or complete filtration.
  • Cooling lubricants
    The machine can be run with oil or with aqueous emulsions. However, we recommend the use of oil as this is far more beneficial to the longevity of the machine.
  • Bar feeder
    All commonly available bar feeders (FMB/IEMCA/LNS) can be used with the machine. The software interface is included in the machine as standard.
  • Chip conveyor
    The machine can be fitted with a chip conveyor or a chip flushing system.
  • Peripherals
    Peripheral components such as parts separators, purchased coolant units (oil/emulsion), coolant filters, fire protection systems and TPM (tool process monitoring) can also be offered. A retrofit of peripheral components is always possible.
