SR-20JN
The new models of series SR
SR-20J and SR-20JN
Continuous enhancements for the successful series SR.
And also these machines offer an excellent cost/performance ratio.
Other advantages are:
- maximum rigidity and flexibility
- enhanced tooling to capitalize on basic and advanced machining
applications
- 2 additional tool stations for deep drilling up to 100 mm
The SR-20JN is a non-guide type (like SR-32JN)
