History of Duval Precision Grinding

Our founder, Richard Duval began his career in Chicopee, Massachusetts working alongside his father in a one man, one machine shop. He continued his education in grinding at the local vocational high school. By 1972, Richard moved his wife and young children to Orange County, California where he built his reputation for his work ethic and quality services. In 1980, Duval Precision Grinding was established and has continued to provide exceptional grinding services throughout the years.
