Precision CNC Machining Tolerances

Reference values vary by geometry, material, feature depth, and process route. Final tolerance review is confirmed during engineering evaluation.
ProcessTypical Tolerance (mm)Best Possible Tolerance (mm)Notes
EDM (Electrical Discharge Machining) +/-0.015 +/-0.005 Tolerance can shift with electrode condition and cut strategy.
Grinding +/-0.005 +/-0.001 Grinding is often selected when surface finish and flatness both matter.
CNC Turning +/-0.025 +/-0.010 Final finish and slender geometry can influence repeatability.
CNC Milling +/-0.025 +/-0.005 Tool reach, cutter selection, and material grade affect precision.

Verified Client Feedback
Trusted by teams shipping precision parts under real production deadlines.

We ordered aluminum manifolds for a pilot build and were watching the sealing surfaces closely. The parts arrived well packed and checked out cleanly during our incoming inspection.

Jonas Eriksen Lead Engineer, Norwegian process equipment startup

What stood out was that the quote review connected design choices to production reality. Our team got clear notes on wall thickness, access, and finish instead of vague suggestions.

Melissa Ward Product Development Manager, US industrial sensor brand

For a control cabinet program, the hardware insertion and bend details matched the released drawing set without surprises. That saved rework on our assembly side.

Petr Svoboda Manufacturing Sourcing Specialist, Czech electrical systems company

We asked for a tooling review before final approval and got specific comments on shutoffs and cosmetic risk. It felt like feedback from people who actually build these parts.

Sharon Lim Program Engineer, Singapore consumer appliances brand

The turned shaft parts were consistent from sample to sample, which mattered because we were checking fit against bearings and seals. That repeatability is hard to fake.

Tyler Hughes Operations Engineer, US motion control supplier

We had one material question mid-order and got a straightforward answer with options, not a delayed sales response. That helped us keep our internal approvals moving.

Elena Petrova Procurement Manager, Polish industrial components distributor

The prototype covers looked good enough for customer demos but still gave us usable fit information. That balance was exactly what we needed at that stage.

Daniel Kim Hardware Lead, South Korean smart device startup

Across a mixed order of parts and jigs, revision control stayed clear all the way through. That made our own internal tracking much easier when the shipment landed.

Laura Green NPI Program Manager, UK medical equipment supplier

FAQ

Choose precision machining when your part requires tight tolerances, repeatable geometry, intricate features, or dependable fit inside an assembly. It is commonly used for aerospace, medical, robotics, electronics, and other critical hardware programs.
Yes. Precision CNC Machining is selected specifically for tighter dimensional windows. Final capability depends on process choice, material behavior, part geometry, and inspection method, but the route is designed for high-accuracy part production.
