Expert Aerospace CNC Machining in Wisconsin

Douglas Machine & Engineering provides CNC milling, lathe turning, fabrication, specialty welding, assembly fixtures, weld tooling, inspection, and finishing coordination. The company machines components up to 20,000 lbs and supports tolerances from +/-.005 to +/-.0005, making its capabilities suitable for aerospace, defense, robotics, agriculture, and other demanding industrial applications.

Yes. Inspection capabilities include first article inspection reporting, CMM analysis through Exact Metrology, dimensional verification using certified granite tables and gauges, and comprehensive quality documentation. These resources help support aerospace, defense, and regulated manufacturing programs where traceability, dimensional accuracy, and verification records are required.

Douglas Machine & Engineering holds AS9100D and ISO 9001:2015 certifications, both important for quality-driven aerospace and defense manufacturing. The company also has AWS certified welders, JCP approval, SAM approval, and Cage Code 87BF4, supporting customers that need a qualified manufacturing partner for regulated or government-related programs.

Yes. The machining operation can produce components up to 20,000 lbs, while fabrication capabilities support structural fabrications up to 20 tons. This combination allows DM&E to serve projects involving larger machined parts, welded assemblies, tooling, fixtures, and integrated components that require both precision and structural capacity.

DM&E operates an in-house paint and powder coating facility and coordinates plating and heat-treat processing through qualified partners. Available finishing support includes thermoset powder coating, liquid finishes, blasting, corrosion-resistant coatings, wear-focused finishes, conductivity-related plating, and heat treatments that improve hardness, strength, and durability.

By managing design, machining, fabrication, inspection, finishing coordination, and supplier processes under one program workflow, DM&E helps customers reduce transportation costs and avoid multiple purchase orders. This approach also keeps quality ownership clearer, improves communication, and minimizes delays caused by handoffs between separate vendors.

In addition to aerospace and defense, Douglas Machine & Engineering serves industrial, pharmaceutical, agricultural, robotics, food grade packaging, and construction customers. The same precision manufacturing, fabrication, inspection, and project management capabilities used for aerospace programs can be adapted to demanding applications across these technical markets.

Start by sharing drawings, specifications, material requirements, tolerances, quantities, inspection needs, and any finishing or delivery expectations. DM&E can review the scope, discuss manufacturability, identify required outside processes, and develop a coordinated production path that supports quality, communication, and on-time delivery from concept through installation.
