POWER, SPEED

AND PERFORMANCE!

The ST-38 from STAR Micronics further develops the series of the complex KNC-32 and SV-32 machines.

A machine for highly complex parts, yet easy to program in the usual way with the FANUC control system with machining possibilities for parts up to a workpiece diameter of 38 mm.

The 3 turrets allow for almost limitless machining flexibility. The ST-38 therefore enables the machining of turned parts which require up to 60 tools.

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* ST-38 with a standard configuration.
