Our Approach

For more than 90 years, Sunnen has been the technology leader of honing systems worldwide.

But beyond the quality, power and precision of our machines and our full range of Sunnen-made tooling and abrasives, it’s the Sunnen approach that truly makes us unique.

When you invest in a Sunnen machine, you not only get best-in-class honing technology, you have access to unparalleled service and support from a team that’s been in the business since 1924.

We work with you to determine the best solution for your needs and we will continue to supply you with the highest-quality tooling and abrasives throughout the life of the machine.

Our Heavy Duty Team

Sunnen’s sales representatives are industry-specific honing experts covering everything from aerospace and hydraulics to oil and gas. And with more than 150 years of collective experience, they know your industry. They understand your needs. They know the challenges you face. They speak your language.

Our field service technicians are available to come to service your machine if anything goes wrong. They investigate the problem and perform diagnostic tests to get your operation up and running as soon as possible.

Plus, our worldwide sales and service team provides comprehensive, in-person support for the installation and operation of every system we make. This includes refresher training courses and getting new employees up to speed.

No matter where you are in the world, Sunnen is there to support you. It’s all part of the added value you get with Sunnen.
