CNC Turned Aluminum Components to Your Drawing
Aluminum turning is a lathe-based process: bar or billet stock rotates while a cutting tool shapes it into shafts, bushings, spindles, standoffs, and threaded fittings. DEK prices against the critical callouts on your drawing, not a flat rate per geometry.
Need pockets, flats, or slots on the same part? Our CNC milling services combine with turning on one drawing and one quote. For mostly milled work, see our aluminum machining services; for other metals, see CNC turning services.
Why Source Aluminum Turning from DEK
OEM engineers, procurement teams, and startups order single prototypes or running production batches from the same lathe cells.
Engineer-Reviewed Quotes
A mechanical engineer reviews every file by hand. Material behavior, tolerance stack-up, and finishing steps all affect the price, so no automated calculator sets your number.
Aluminum Turning Capabilities
Aluminum's machinability supports the full range of lathe operations, quoted and inspected to the dimensions your drawing flags as critical.
Aluminum Turning vs. Other Machining Options
Choose turning for rotationally symmetric aluminum parts that must be light and corrosion-resistant. See how CNC turning works.
| Criteria | This ProcessAluminum Turning | CNC Milling | Brass Turned Parts | Carbon Steel Turned Parts |
|---|---|---|---|---|
| Best for | Shafts, bushings, standoffs | Pockets, flats, slots | Connectors, fittings | Same fit and finish in steel |
| Geometry | Rotationally symmetric | Mostly milled parts | Turned parts | Turned parts |
| Material trait | Light, corrosion-resistant | Full aluminum milling set | Conductivity, bearing wear | Carbon steel |
| Choose when | Weight matters | Part is mostly milled | Aluminum lacks conductivity | Steel is specified |
Industries Using Turned Aluminum Parts
Aerospace, medical device, robotics, and semiconductor equipment teams source turned aluminum where parts must be light and corrosion-resistant.
Turned Features & Challenges We Solve
From stepped shafts to micro-turned parts, these are the turned aluminum geometries we machine and the issues we control.
-
Shafts & Stepped Diameters
Contour, straight, and taper turning for custom shafts, stepped diameters, and conical fittings.
-
Threads & Knurling
Threads and knurls for fasteners, grip surfaces, and mating connectors; fit-critical pitch diameters to ±0.005 mm.
-
Cross-Holes, Flats & Keyways
Live tooling cuts secondary milled features in the same setup, without re-fixturing, at ±0.01 mm profile control.
-
Micro-Turned Components
Sub-10 mm outer diameters held to ±0.003 mm with CMM inspection at FAI. See micro machining.
-
Large Turned Components
Turned structural parts up to ~1000 mm long. Related: large part CNC machining.
-
Bushings & Standoffs
Bushings, couplings, and standoffs for motion assemblies and fluid-handling lines.
Common Challenges We Handle
-
Thin-Wall Deflection
We reduce cutting forces, support the wall in the workholding, and finish with light passes so thin walls stay round within tolerance.
-
Shaft-Bore Coaxiality
Coaxial features and press fits held to ±0.005 mm, verified by CMM at FAI and OQC rather than sampled from the cutting program.
-
Tool Marks Before Coating
A polished or bead-blasted pass before anodizing removes visible tool marks for consistent color and corrosion protection.
-
Bare Metal After Anodizing
Threads, bores, and mating faces are masked with tape or plugs to stay bare for press fits, electrical continuity, or grounding.
Certified Quality on Every Batch
ISO 9001, AS9100D, and ISO 13485 certified through TUV, with in-house CMM inspection.
