Campbell Grinder Company was incorporated in 1969 to succeed a proprietorship known as “Seaway Machinery,” which was owned by Hugh Campbell. He had a lifetime of experience in the design and construction of special machine tools, including 10 years as Chief Engineer for the Frauenthal Grinder Division of Kaydon Bearing in Muskegon, Michigan. He was responsible for the design and construction of all the grinding machines sold under the name of “Frauenthal.” These dependable machines are still in use in the bearing, aircraft and aerospace fields. Fifty year old (and older) Frauenthal models are still in demand in the used machinery market.

Hugh Campbell continued to design and build custom machinery independently as Seaway Machinery, after the Frauenthal Division was sold to Bullard in the early sixties. The accelerating demand for this type of equipment created the need for a larger organization and facility, and the Campbell Grinder Company was organized to meet that demand.
