Citizen BNJ SY7: you don’t need a Y-axis to finish parts in a single setup!
By Tom Skubala
More power, upgraded spindles, and a redesigned second turret with fully interchangeable tooling. Meet the Citizen Miyano BNJ SY7, running one of the coolest demos out there.
This demo shows how the SY7 handles simultaneous machining, crisp knurling, and complex features using polar coordinates – all completed in a single setup.
The result? A finished part straight off the machine, proving that smart programming and strong application support can turn perceived limitations into real capability. Learn more in this conversation with MTDCNC’s Tom Skubala and Citizen’s Chris Downham.
