CNC automatic lathes

SW-20

The SW-20 CNC automatic lathe is equipped with 2 tool posts to enable overlapped machining on the front side, e.g. simultaneus balance cut machining, milling or cross drilling.

In addition, the SW-20 achieves unique value for money by using the latest FANUC 31i-B5 high speed control system.

Advantages

  • FANUC 31i-B5 control system with electronic handwheel
  • C axis control as standard on main and sub spindle
  • fully independent backworking with 8 stations
  • movable control panel
  • 2 tool posts for simultaneous machining on the front side
  • additional longitudinal axis on the tool post 3
  • three fully independent tool systems

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.
  • Service
    SSC star* Service Connect as 24/7 customer portal and online connectivity for your machines, tickets and service calls. A current overview can be called up at any time. In addition, you have access to the star* knowledge database

You will receive a quotation for a star* SW-20 with a standard configuration.
