When a part calls for ±0.005 mm tolerances and Ra 0.2 μm surface finish, you're in high-precision territory. Most machine shops can hold that for one part. Doing it consistently across a production run — that takes process control, good equipment, and experienced programmers. That's what CNC high-precision parts processing looks like at AOOM.
I remember a fuel-injection nozzle job we ran for an automotive Tier 1 supplier. The print called for a 0.3 mm diameter cross-hole with a positional tolerance of 0.01 mm. One wrong step and the part scraped. We dialed the program in, ran a full first-article validation, and delivered 8,000 units with zero rejects. The client had never seen that kind of repeatability from a Chinese CNC shop.
Our CNC high-precision parts processing covers milling, turning, and multi-axis work. Our shop floor has 5-axis machines that let us machine complex geometries in one setup. That's critical for precision because every setup change introduces alignment error. Fewer setups means tighter parts.
We process aluminum, titanium, stainless steel, and engineering plastics. Surface finishes down to Ra 0.2 μm. Tolerances as tight as ±0.005 mm. And we scale from single prototypes to high-volume production runs while maintaining that consistency.
We serve aerospace, medical, automotive, and electronics clients. Aerospace landing gear components require flawless surface integrity — no micro-cracks, no burrs. Medical implants demand biocompatible finishes and dimensional accuracy that fits every time. Automotive fuel systems need leak-free sealing surfaces.
When a part goes into a critical assembly, there's no room for "close enough." Our ISO 9001-certified quality system makes sure every dimension matches the GD&T callouts on your print.
Before we cut any chips, our engineers review your design. We look for features that are hard to hold — thin walls, deep cavities, sharp internal corners. We suggest practical modifications that preserve function while making the part easier to machine. That DFM review alone often cuts 10-20% off the production cost.
