Peterson Wash & Blast Systems better known as Peterson Machine Tool has a long and varied presence in the automotive machine shop equipment manufacturing area. Mr. Peterson started out in 1948 in Kansas City MO with a solid stone push over surfacing machine that was so durable and popular that we still get calls for it this day. With the change from in frame engine overhauling to complete engine rebuilding, Peterson Machine Tool responded with the ever changing field. We developed more accurate surfacing machines and partnered with several other companies to market a complete line of machine shop equipment. In 1978, Kansas Instruments was acquired as a subsidy of Peterson in Council Grove KS. The KI brand specialized in sheet metal construction which included our first wash cabinet and cylinder hones. Peterson Machine Tool and Kansas Instruments became the leading manufacturer of cleaning equipment.
