Generations of Excellence

Welcome to Roberts Automatic Products

Roberts Automatic Products was founded in 1947 by Glen Roberts, a pioneer in the Minneapolis screw machine parts and products industry. Since our inception, we have been a leading supplier of quality precision production machining. Roberts Automatic has grown and prospered, due in part to solid values of both the owners and employees of the company. 

Roberts Automatic Products is a division of the Smith & Richardson Manufacturing Group. The Smith & Richardson Manufacturing Group provides unparalleled depth and breadth of precision machining capabilities and services to a wide range of industries.
