J.E. Marble Precision Deburring, formerly known as Marble Engineering, was founded by James E. Marble in 1953 and was located in North Weymouth, MA. Our expertise is the removal of burrs from machined pieces (visual to 30x) on all components for defense, aeronautical, aerospace, medical, electronics, communications, radar, sonar, and a variety of other fields. Our process helps our clients save thousands on production expenses. Rather than compensating a highly skilled machinist to do such work, our staff can do it for you at a lower cost. And, untrained staff have the most difficulty deburring the constricted inner passages of a machined part, wasting both material and time. We only remove the burr and do not touch any base material that may change dimensions of the piece. We can also alert you to quality control issues that may cause your machined pieces to fall out of specifications when finished. we can give you any edge break or radius. We do not use chemicals or tumble parts.
