About Supfina Machine Company, Inc.

Precision is our passion

As one of the world’s leading manufacturers of surface-finishing systems, Supfina has decades of cutting-edge experience in the precision superfinishing of automotive and bearing components.  Deeply rooted in German technology, we have devoted considerable resources to researching and developing the best professional solutions for our customers. 

Given this ongoing commitment to technological innovation, it’s only natural that we’d use our years of process expertise to expand our product line to include fine grinding.  And with our new Spiro series of high-precision machines—two of which will make their North American debut at this year’s IMTS—we have done just that.

These latest additions to our extensive product and technology portfolio—which also includes our Nano machine for flat finishing—are in keeping with Supfina’s philosophy of providing you with maximum benefits: lower operating and unit costs; better reliability; and higher energy efficiency, to name just a few.  After all, when you succeed and profit, so does Supfina. 

Precision is our passion.  We build machines that create—to your exact requirements—the perfect surface for your parts.  Combine this know-how with excellent customer service and you’ll understand why Supfina continues to be so successful.

Quality, precision, and reliability: These core values ​​drive us to be the technology leader.  To see that technology up close and in action, please visit us at our booth.
