Welcome to Roberts Prototype Machining.

Roberts’ Prototype Machining is a job shop in the Chelmsford MA area that has been serving a variety of businesses for the past 20 years, including the semi-conductor, medical, aerospace and 3d printer industries. Not just for prototypes anymore, we are capable of producing high volumes of parts on our quality vertical machining centers.

We pride ourselves on customer service. At times, extremely quick turnaround is possible. We have had customers bring us parts that need to be modified and wait while we do it! That’s not always possible but we will make every effort to get your parts machined or modified as quickly as possible. Just ask! Our job is to solve your problems.
