CNC Machining
Advanced CNC mills, lathes, and fabrication equipment support precision components up to 20,000 lbs, with tight tolerances from +/-.005 to +/-.0005 for demanding industrial applications.
Douglas Machine & Engineering delivers precision CNC machining, fabrication, inspection, finishing, and automation support for Wisconsin manufacturers that cannot compromise on tolerance, documentation, or delivery. From aerospace and defense components to agricultural, robotics, and industrial production needs, our team manages complex work from concept through installation with quality-driven planning and transparent communication.

Integrated machining, fabrication, inspection, finishing, and automation capabilities for demanding production and custom manufacturing projects.
Advanced CNC mills, lathes, and fabrication equipment support precision components up to 20,000 lbs, with tight tolerances from +/-.005 to +/-.0005 for demanding industrial applications.
Full-scope fabrication services include specialty welding, structural fabrications up to 20 tons, assembly fixtures, hydraulic tooling, electronic weld tooling, and concept-to-installation project execution.
Quality verification includes first article inspection reporting, CMM analysis through Exact Metrology, dimensional checks on certified granite tables, gauges, and documentation for regulated industries.
In-house paint and powder coating capabilities include thermoset powder finishes, liquid coatings, blast preparation, and consultative finish planning for custom metal parts and assemblies.
Precision heat-treat processing is coordinated through certified supply partners to improve hardness, strength, durability, and metallurgical compliance for machined and fabricated components.
Turnkey robotic and automation systems include custom robotic welding units, assembly solutions, system retrofits, full unit testing, on-site setup, and validation for industrial workflows.

We begin by reviewing drawings, tolerances, materials, documentation requirements, and production goals. For Wisconsin manufacturers serving regulated markets, this helps align scope, quality expectations, and delivery planning before work begins.
