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:

  • 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)
