Darmann Abrasive Products

Darmann was founded in 1983 to address the emerging needs of bearing and automotive companies to improve the performance of their products. They found that superfinishing of raceways and rollers resulted in increased bearing life, reduced noise levels and increased load carrying capacity.

The company developed proprietary process technology capable of producing consistent, tightly graded products manufactured to precise geometries. This allowed Darmann to make a more uniform and consistent product. Superior products combined with technical support enabled Darmann to become the superfinishing market leader. Initially we supplied stones to customers in the bearing and automotive industries. The company later utilized the same core technology to make wheels used in the production of orthopedic implants, fuel injection parts and hydraulic components.

In the early 1990s Darmann began to develop targeted CBN and diamond solutions for precision grinding applications, including wheels for small bore grinding, fuel injection and specialized materials such as ceramics. The company has accumulated considerable experience making wheels as small as a pencil head and products that utilize sub-micron abrasive materials.

Since 2004 Darmann has designed, manufactured and sold both metal bond and vitrified honing stones. Our metal bonded products have been used for transmission parts, diesel engine cylinder liners and long tube honing applications. We have developed vitrified superabrasive products for precise plateau honing applications as well as cost effective conventional vitrified hone solutions.

International customers are a very important part of our business. We have established sales and distribution companies in Poland, China, Brazil and Mexico to support customers in nearly thirty countries.

We are committed to supplying customer centric solutions. As an employee-owned company, all of our employees have an equity interest in our success.
