Need high-volume CNC turned parts delivered on time, without compromise? Douglas Machine & Engineering operates an AS9100D and ISO 9001:2015 certified production shop purpose-built for large, precise lathe turning at wholesale scale. From aerospace components to industrial assemblies, we hold tolerances as tight as +/-.0005 and manage every step—design through delivery—so your bulk orders ship fast and right.
Comprehensive large-part CNC turning and supporting capabilities for demanding bulk production requirements across multiple industries.
Precision lathe turning for components up to 20,000 lbs with tolerances from +/-.005 to +/-.0005. Ideal for high-volume wholesale orders in aerospace, defense, and industrial sectors requiring consistent, repeatable accuracy.
Complementary CNC milling and full-scope fabrication services supporting turned components, including structural builds up to 20 tons, executed entirely in-house from design through final delivery.
Rigorous first article inspection (FAI), CMM coordinate measurement, and dimensional verification on certified granite tables ensure every bulk-turned part meets specification before shipment.
Integrated heat treat processing through certified partners enhances hardness and durability of turned components. In-house powder coating and plating via qualified suppliers complete the finish workflow.
AWS certified specialty welding integrated directly into turned-part assemblies and fabrication workflows, eliminating the need for separate subcontract purchase orders and reducing lead times.
Guaranteed spare parts manufacturing availability for ten or more years post-order, ensuring continuity of supply for wholesale customers with ongoing or long-lifecycle production programs.
Our in-house design team reviews your bulk order specifications using PTC Creo, CATIA v5, and AutoCAD. We clarify tolerances, material requirements, and delivery expectations up front, establishing a clear production roadmap before a single chip is cut.
DM&E combines AS9100D-certified quality, expanded production capacity, and single-source project management to make high-volume CNC turning straightforward and reliable.
AS9100D and ISO 9001:2015 certifications guarantee every bulk turned part meets rigorous aerospace and industrial quality standards.
From design and CNC turning to heat treat, finishing, and inspection—all managed under one roof, eliminating multiple POs and costly freight.
Our newly expanded CNC production shop handles large components up to 20,000 lbs, built specifically for the throughput that wholesale bulk orders require.
Careful planning, transparent communication, and dedicated project management keep your wholesale order on schedule—every time.
Skilled manufacturing professionals dedicated to precision, quality, and on-time delivery.
