About Us


History :: 

We are a locally owned corporation now in our 39th year of business. Started in 1980, Stone Machine Company has grown from a 3 employee garage shop to nearly 30 employees. In 1989 a new 8500 square foot building was constructed on a 19 acre site. The business was moved to this new location in March of 1990. Then, in 2002, we enlarged the shop to 10,500 square feet. 

Our Philosophy :: 

We believe quality machined parts are a direct result of qualified individuals working together for a common accomplishment: a high quality finished product. We recognize the service we provide is special and is what helps differentiate Stone Machine from all others. We strive to provide our customers the best parts at competitive prices. The success of Stone Machine relies on this.
