Aerospace CNC Machining & Precision Parts Services for California

Douglas Machine & Engineering provides CNC milling, lathe turning, precision fabrication, AWS certified welding, assembly fixtures, inspection, finishing coordination, paint, powder coating, plating support, and heat treat coordination. The company manages work from concept through installation, helping California aerospace customers reduce vendor handoffs while maintaining quality oversight and documentation throughout production.

DM&E machines components to precise tolerances ranging from +/-.005 to +/-.0005, depending on the part geometry, material requirements, setup, and inspection plan. These capabilities support demanding aerospace, defense, robotics, and industrial applications where dimensional consistency, documented verification, and controlled manufacturing processes are essential to performance and compliance.

Yes. Douglas Machine & Engineering is AS9100D certified and ISO 9001:2015 certified, supporting quality management expectations for aerospace, defense, and regulated manufacturing. The company also has AWS certified welders, JCP approval, SAM approval, cyber security insurance, and CAGE Code 87BF4 for defense supplier identification.

Yes. DM&E provides rigorous inspection and quality verification, including first article inspection reporting, dimensional verification, certified granite table checks, gauges, and CMM analysis through Exact Metrology. These inspection resources help support aerospace documentation, production approval, and regulated industry requirements where traceable measurements and quality records matter.

Yes. DM&E offers in-house paint and powder coating, including thermoset finishes such as epoxy, polyester, nylon, polyurethane, and metallic coatings. The company also coordinates plating and heat treat services through qualified partners, integrating those processes into the project workflow for corrosion resistance, durability, wear performance, and specification compliance.

DM&E can machine components up to 20,000 lbs and build structural fabrications up to 20 tons. Its capabilities include CNC machining, fabrication, specialty welding, assembly fixtures, hydraulic and electronic weld tooling, and full fabrication workflows, making it suitable for complex, heavy, and high-value aerospace or industrial component programs.

DM&E operates as a one-stop shop with in-house design, machining, fabrication, inspection, paint, powder coating, and project management. When outside processes are required, such as plating or heat treating, DM&E coordinates qualified suppliers. This reduces transportation costs, minimizes multiple purchase orders, and keeps finished product quality under coordinated oversight.

In addition to aerospace and defense, Douglas Machine & Engineering serves industrial, pharmaceutical, agricultural, robotics, food grade packaging, and construction customers. Its combination of CNC machining, fabrication, inspection, finishing, tooling, and automation integration is designed for demanding applications that require careful planning, tight execution, and reliable communication.
