If your parts exceed our standard size or tolerance guidelines, simply request a custom quote—our engineers will tailor the optimal manufacturing solution to your exact specifications.
CNC Machining Tolerance
Selecting the right tolerance for your part is critical for its use and to control costs. The higher the tolerance the better the part but the more costly. We can help you choose the right balance of precision to cost.
Maximum Part Size
Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). Lathe parts up to 62” (1,575 mm) length and 32” (813 mm) diameter.
General Tolerance
Tolerances on metals will be held to +/- 0.005″ (+/- 0.127 mm). Plastics and composites will be +/- 0.010”.
Precision Tolerance
We can manufacture and inspect to tight tolerances, including sub +/- 0.001″ tolerances.
Threads and Tapped Holes
We can accommodate any standard thread size.
Edge Condition
Sharp edges are broken and deburred by default
Surface Finish
The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified during the quoting process.

FAQ
Our team is ready to help you with any question
What CNC machining processes does Oak Engineering & Manufacturing offer for aerospace components?
We provide 3-, 4-, and 5-axis CNC milling; precision CNC turning and specialized drilling and tapping. Our multi-axis centers and high-speed spindles let us tackle everything from simple brackets to complex turbomachinery parts.
Which aerospace-grade materials can you machine?
We routinely work with aluminum alloys, titanium, stainless and tool steels, and other nickel-based superalloys, plus high-performance plastics. If you need another alloy, just ask—we’ll source it for your project.
What tolerances and surface finishes can Oak Engineering achieve?
Standard tolerances are ±0.002″ (±0.05 mm); in many cases we can hold ±0.005″ (±0.12 mm). Surface finishes down to 125 Ra or better. Post-machining treatments are also available to meet your spec.
What are your maximum part-size limits and production capacities?
We handle both one-off prototypes and high-volume runs—our flexible cell layout lets us scale quickly to meet batch sizes from single pieces to thousands.
How do I request a quote for aerospace CNC machining?
Simply send us your 3D CAD file (STEP or IGES), material spec, quantity, and any special tolerances or surface treatments. You can upload everything through our online quote form or email it to sales@oakengineering.com—our team will respond with a detailed estimate within one business day.
