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.
