"The Supfina machine has really advanced Hirschmann."
Rainer Harter, CTO of HIRSCHMANN GmbH
“It’s the quality of the finish. We’ve tried times to do jobs without the superfinishing attachment, but it’s needed that process, as the grinding process was leaving inclusions in the material, and Superfinishing was the only way to remove those inclusions.”
Ted Ashley, Owner of NMI
