Trustbridge CNC Machining | Precision Manufacturing & Expert Design Support

Trustbridge delivers precision CNC machining services through our global network of certified and highly vetted manufacturing partners. Whether you need rapid prototypes, small-batch production, or full-scale part runs, we match your exact technical requirements to the right supplier — based on capabilities, certifications, location, and lead time.

From simple brackets to complex 5-axis parts, our platform gives you access to the full range of CNC milling and turning technologies, coupled with in-house engineering support to ensure your parts meet spec the first time — and every time. Trustbridge is your smarter sourcing solution for tight tolerances, high-performance materials, and scalable production.

What Tolerances Can You Expect?

Our partners routinely achieve industry-standard and tight-tolerance CNC specs:

Standard Tolerance: ±0.005 in (0.127 mm)
Tight Tolerance Option: ±0.001 in (0.025 mm) upon review
Surface Finish Range: 63–125 Ra standard; down to 16 Ra with polishing or lapping
Post-Processing Options: Anodizing, powder coating, plating, bead blasting, and more

If your project requires ultra-precision machining, we’ll match you with facilities equipped for aerospace-grade tolerance control.
