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

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

We needed someone who could support early samples and then stay with us through short production runs. That continuity matters once procurement takes over from engineering.

Clara Dubois Commodity Manager, French mobility components company

The soft-tool parts were presentable enough for customer meetings, which helped us bridge an awkward phase before production tooling was ready.

Ryan Patel Product Development Engineer, Canadian healthcare startup

Our order was not large, but the drawing notes and dimensional callouts were still handled carefully. That gave us confidence to come back with a bigger program later.

Georgia Hunt Lab Operations Lead, Australian energy research team

Packaging held up well during international transit, which was one of our concerns on a mixed metal parts order. Nothing arrived loose or confused in the box.

Rafael Mendes Purchasing Supervisor, Brazilian machinery supplier

The feedback during quoting helped us fix a problem before release rather than after samples. That saved time we really did not have in the program.

Chloe Bennett Mechanical Engineer, New Zealand agritech company

We now keep Zigitech in the mix whenever a program needs fast review, clear communication, and dependable export delivery. They have been steady across several orders.

Marco Conti Sourcing Manager, Italian motion systems manufacturer

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

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.
