Douglas Machine & Engineering (DM&E) is an ISO 9001:2015 and AS9100D certified precision manufacturing company serving aerospace, defense, agricultural, robotics, food grade packaging, pharmaceutical, construction, and industrial sectors. Operating as a true one-stop-shop, DM&E manages every project from initial concept and in-house design engineering through CNC machining, fabrication, finishing, inspection, and final installation. The company recently expanded its capabilities with the grand opening of a new CNC Machining production shop, demonstrating a forward-looking commitment to higher production value and enhanced capacity. With AWS certified welders, FeatureCAM CNC programming, and advanced metrology resources, DM&E's skilled workforce is dedicated to exceeding customer expectations through careful planning, transparent communication, and timely delivery on every job.
CNC (Computer Numerical Control) machining refers to the automated process of using computer-controlled machines to cut and shape materials. Precision machining is a broader term referring to any machining process that achieves very tight dimensional tolerances. Precision CNC machining combines both—using CNC automation to consistently achieve extremely accurate tolerances, often as tight as +/-.0005 inches, as DM&E delivers.
