Swiss roots, global performance, one amazing innovation!
By Tony Gunn
What happens when nearly 100 years of Swiss innovation meets modern CNC challenges?
Tony Gunn of MTDCNC chats with Sebastien Dunner (4th generation of Dunner!) to uncover the secrets behind their groundbreaking DunnAir system—a pneumatic guide bushing that adapts to raw material imperfections, reduces vibration, and keeps your machine running through the night while you sleep stress-free.
From ceramic-lined guide bushings that conquer sticky materials like titanium to collets engineered for tighter tolerances and longer tool life, Dunner is redefining precision in Swiss machining.
If your shop struggles with tolerance variation, part centering, or bar feed jamming—this conversation is your roadmap for higher uptime, smarter investment, and a smoother path to production.
