Thread milling - our pride and joy - is a technology known to some but mastered by very few. At McMellon we have a large variety of Hanson-Whitney, Sunstrand and Lees-Bradner Thread Millers ranging in Diameter and length.

When squareness, circularity,
concentricity, and true position are called for in threads, thread milling is the answer. We have the largest selection of operating thread milling machines in New England.

Our thread gaging skills are unmatched in the industry... here skilled hands perform Method C Thread Gaging on our own design thread gaging equipment developed over the years to meet this most rigid of gaging specifications.

We are also capable of precision milling operations with an extensive resource or Bridgeport and Cincinnati vertical and horizontal milling machines. Along with this, we have grinding and lapping facilities.
