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.

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
Müller Products can easily be combined with and configured to your star* machine.
