Campbell Grinder Company Campbell Grinder Company manufactures CBN, Creep Feed, CNC, Rotary and ID/OD grinding machines. Campbell specializes in machines for the aircraft engine industry as well as hand tools, bearings, power generation, and defense industries. These machines are capable of grinding materials ranging from super alloys to ceramics. 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 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. Used Frauenthal models 50+ years and older 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 Campbell Grinder Company was organized to meet that demand. The Campbell family retained ownership until 1998, when they sold the business to Charterhouse of New York. Charterhouse held the business until fall of 2005. Charterhouse held the business until fall of 2005, when Campbell Grinders three managing executives purchased the company. This ownership has allowed Campbell Grinder Company, to diversify into other markets and offer (8) standard models as well as the custom machines. The Muskegon Tooling Alliance of West Michigan (MTA) was formed in July 2006. Campbell Grinder Company is part of the MTA which also includes other West Michigan tool and die companies with diverse capabilities, technologies and resources. The main reason for forming our tooling collaborative is to utilize and share our technologies in design, machining and equipment. Campbell Grinder Company receives the "2007 Muskegon Area Environmental Excellence Award". Campbell Grinder Company announces the formation of its new MicroTech Filtration Division. The new division will first concentrate on the development of three exclusive MicroTech product lines matched to the specific requirements of Campbell Grinder application and then later expand the MicroTech products to handle any single or central machine tool coolant filtration application up to 4000 GPM. Glencoe Capital, LLC ("Glencoe Capital"), a private equity firm focused on control acquisitions and growth equity investments in lower middle-market companies, announced that its Glencoe Capital Michigan Opportunities Fund has acquired Campbell Grinder Company, a manufacturer and provider of high-precision grinding machines, state-of-the-art "green" filtration systems, and custom design, process optimization, and employee training services.
