Precision by Design

Process development is how Sunnen puts our decades of honing and deep hole drilling experience to the test. When our customers embark on ambitious projects, like new applications or assemblies, they come to us first. We leverage every resource we have to create the right honing procedures and workflows for their demanding needs.

Led by Experience

We’re not just honing parts anymore—we’re honing processes. And we’re not afraid to get our hands dirty. Sunnen technicians lead the charge to design productive honing platforms for our customers ’operations. Whether they require a custom buildout or something off the shelf, our processes are designed for efficiency, profitability and—above all—performance.

Sunnen’s Advanced Technology Center is home to all the latest Sunnen machines, tools and abrasives, plus a full range of metrology instruments . They allow us to refine and test levels of performance our customers could never achieve on their own. The result is a honing system that’s been thoroughly vetted and validated—before it ever reaches our customers’ facilities.
