type B
MAXimum DIAMETER
MINimum PRODUCTION COSTS
In comparison to its proven small brother the SR-20R IV, the new SR-38 type A/B automatic lathe has an extended material passage of 38 mm. In addition, the tool post can be used for simultaneous rough machining and finishing (X3 axis). The swivelling B axis offers additional cross machining possibilities.
Advantages
- FANUC 31i-B5 control system with handle
- C axis control as standard on main and sub spindle
- fully independent backworking with 8 stations
- convertible from sliding headstock to fixed headstock lathe
- movable control panel
- additional X3 axis for simultaneous turning on the front side
- B axis programmable for main and sub spindle on the tool post

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.
