Custom Precision Metal Machining Services

Douglas Machine & Engineering supports industrial, aerospace and defense, pharmaceutical, agricultural, robotics, food grade packaging, and construction customers. The company’s capabilities are suited for demanding applications that require precision machining, specialty fabrication, quality documentation, controlled finishing, and coordinated program management from early concept through finished product delivery.

DM&E’s CNC machining capabilities include precise tolerance ranges from approximately +/-.005 to +/-.0005, depending on the part geometry, material, process, inspection requirements, and production conditions. Projects are reviewed up front so the team can confirm feasibility, plan the right machining strategy, and apply the appropriate verification methods.

Yes. DM&E is structured as a one-stop manufacturing partner with in-house design, CNC machining, fabrication, welding, paint and powder coating, inspection, and program management. Processes not completed in-house, such as plating or heat treat, can be coordinated through qualified partners to reduce vendor complexity and keep accountability centralized.

Yes. Inspection and quality verification can include first article inspection reporting, CMM analysis through Exact Metrology, dimensional checks on certified granite tables, gauge verification, and comprehensive documentation. These services help support aerospace, defense, and other regulated or specification-driven manufacturing requirements where traceability and dimensional confidence matter.

Douglas Machine & Engineering is ISO 9001:2015 certified and AS9100D certified, supporting quality management requirements for precision manufacturing and aerospace-related work. The company also has AWS certified welders, is JCP approved, SAM approved, carries Cage Code 87BF4, and is cyber security insured for added customer confidence.

DM&E can machine components up to 20,000 lbs and build structural fabrications up to 20 tons. These capabilities make the company a strong fit for large industrial parts, heavy assemblies, fixtures, tooling, and complex fabricated structures that require precision, weld quality, finishing, and inspection support.

DM&E can work from customer-supplied drawings and specifications, but the company also offers in-house design capabilities. The team can take a concept, develop a manufacturing process, coordinate necessary steps, and produce a finished product, helping customers refine projects before they enter machining, fabrication, finishing, and inspection.

By managing multiple manufacturing steps under one coordinated workflow, DM&E helps customers avoid separate purchase orders, excessive transportation, and fragmented communication between vendors. The team oversees in-house processes and qualified supplier coordination, keeping quality, scheduling, documentation, and issue resolution connected throughout the program.
