CNC Turning Services
Precision CNC turning for aerospace shafts, bushings, and housings. AS9100 and ITAR-registered, with tight concentricity, clean finish, and multi-axis capability.
Overview
What Is CNC Turning?
CNC turning is the process of shaping a rotating part with computer-run cutting tools on a lathe. As a result, EGM Manufacturing, a CNC turned parts manufacturer based in Sunrise, Florida, makes shafts, bushings, housings, and connectors with tight concentricity and clean surface finish, so every part meets the tough needs of aerospace and defense assemblies.
As a CNC turning company, EGM delivers precision rotating parts built for aerospace and defense programs. To start, our team reviews every CAD file to confirm the part can be made, then runs the job on multi-axis lathes staffed by seasoned machinists. Because of this careful review, our AS9100 and ITAR-registered shop supports buyers who cannot accept runout drift or late delivery. In the same setup, the turning cell also handles threading, grooving, and tight-tolerance features, with CNC swiss turning services and CNC vertical turning services available for parts that call for a different chucking approach. As a result, and with no volume minimums and fair pricing, EGM scales from one prototype to 1,000+ units.
For teams that need round and machined features on the same part, our CNC turning and milling services combine lathe work with our multi-axis CNC milling cell, so shafts, flats, and cross-holes come off the same job traveler.

Aerospace & Defense
Why CNC Turning Matters for Aerospace and Defense
When a rotating part fails in a flight or defense system, the result is total loss of function. That's why aerospace and defense buyers demand CNC turning done inside a certified quality system. After all, tight runout, strength, and repeat accuracy are not optional on shafts, bushings, or pressure housings. Specifically, a turned part that holds clean threads and true runout keeps the assembly safe and steady under load. On top of that, EGM runs every turning job inside the same quality system used for milled work, so paperwork stays in one place, whether the job needs standalone turning or full CNC milling and turning services on one part.
Multi-Axis Value
Is Multi-Axis Turning Worth the Cost Over Standard Lathe Work?
Often, yes. Multi-axis turning mixes threading, grooving, milled flats, cross-holes, and turned features in one setup. As a result, buyers save on fixture cost, setup time, and handling error, and runout stays tight because the part never leaves the chuck. In the end, total part cost usually drops despite higher hourly rates.
Our Process
How Our CNC Turning Process Works
Every CNC turning job at EGM follows a clear workflow:
- Your team submits CAD files, 2D drawings, and material specs
- Our engineers review the package, confirm the part can be made, and plan tooling
- The job goes to the right lathe based on size, length, and how complex the features are
- Our CMM checks key dimensions against print, including runout, diameter, and threaded features
- We ship with full paperwork, including inspection reports, material certifications, and certificates of conformance for your records
Programs that start as a single article often move through our CNC prototyping service before scaling into short run production, all without switching suppliers.
Materials
What Materials Does EGM Turn for Aerospace Parts?
EGM routinely turns aerospace-grade aluminum alloys like 6061, 6061-T6, 6082, and 7075. In addition, we cut stainless steels like 303, 304, 316, 17-4, 420, and 2205 duplex, along with titanium, brass, copper, alloy and tool steels. Beyond metals, our CNC plastic turning services cover PEEK, PTFE, Delrin, UHMW, and G-10. Even so, custom materials get case-by-case review.

FAQ
Frequently Asked Questions About CNC Turning Services
EGM can turn parts up to Ø 350 x 600 mm, or roughly Ø 13.8 x 23.6 inches. Plus, we hold minimum feature sizes down to 0.50 mm in diameter. Therefore, large shafts, housings, and small precision bushings all fit within our shop envelope.
Standard turned batches under 50 parts can ship as quickly as 8 days. However, complex multi-axis work, exotic alloys, or special finishes push out the timeline. Therefore, our team gives an exact delivery date at quote — not after the job starts — so aerospace and defense program schedules stay on track.
Yes. Our multi-axis lathes handle single-point threading, tapped holes, outer and inner grooves, live-tool milled features, cross-holes, and face slots. Plus, all of these steps can run in one setup. Therefore, buyers get complete rotating parts without routing the job to a second milling step.
Yes. EGM Manufacturing is ITAR registered and holds a JCP Certification (DD2345). As a result, we can receive and handle controlled unclassified information and defense-related technical data. Plus, all ITAR drawings run through secure systems with access limited to cleared staff. Please contact our team before sending any controlled package.
Runout depends on material, length-to-diameter ratio, and how complex the feature is. However, EGM routinely holds runout within ±0.001″ on standard aerospace shafts. Plus, tighter specs are possible on short parts with proper fixturing. Therefore, please send your drawing with concentricity callouts and our team will confirm what we can hold at quote.
