DFM first
Feasibility, process fit, and tolerance economy are reviewed with your CAD before we lock a quote.
About Zonclair
Precision CNC machining and custom hardware from Dongguan — multi-axis milling, Swiss turning, Wire EDM, finishing, and in-house inspection with DFM before we cut.
Who we are
Zonclair is the export-facing partner for B2B buyers who need precision CNC components and custom hardware from Dongguan. We coordinate DFM, quoting, and production with authorized manufacturing partners so automation, robotics, and industrial equipment teams get clear manufacturability feedback before metal is cut.
How we work
Flexible volume
From single-piece prototypes to low-volume production without forcing a separate vendor path.
Dongguan supply base
Machining, common finishing partners, and material stock coordinated to keep multi-process jobs coherent.
IP and communication
NDA available before file exchange; project files limited to assigned engineers. See Contact for channels.
Manufacturing environment
Our Dongguan shop runs enclosed CNC cells for milling, turning, and related processes in an organized production bay. Equipment brands and envelopes listed on Capabilities are reference platforms — we confirm fit for your part during DFM rather than promising a specific machine for every job.
DFM collaboration and materials
Drawing and tolerance review
Engineers mark critical dimensions and confirm which limits are worth the cost before cutting.
Stocked material families
Aluminum, steels, copper alloys, and engineering plastics planned against your print.
Technical baseline (reference)
| Area | Reference |
|---|---|
| Multi-axis / 5-axis | Mazak / Brother / Fanuc class centers; envelope up to about 800 × 600 × 500 mm |
| Swiss / turn-mill | About Ø0.5–32 mm Swiss; chuck turning up to about Ø250 mm |
| Wire EDM | Sodick / Charmilles class; sharp internals on conductive / hardened stock |
| Tolerance posture | ±0.10 mm common standard delivery; selected milling/turning features to ±0.01 mm; designated critical 5-axis features to ±0.005 mm where allowed — confirmed via DFM / per drawing |
Explore processes
Five-Axis CNC
Complex multi-face parts in fewer setups.
CNC Milling
Pockets, housings, and structural milling.
CNC Turning
Shafts, fittings, and live-tool turn-mill.
Custom screw machining
Swiss-type fasteners and threaded prints.
Wire EDM
Hardened profiles and narrow slots.
Quality control
IQC / IPQC / FQC and CMM on request.
Quality, NDA, and response
IQC checks incoming material documentation where required; IPQC covers setup and in-process checks; FQC verifies against the drawing and agreed plan before ship. In-house metrology includes ZEISS CMM and shop gauges. “100% inspection” means in-house pre-shipment verification to the agreed scope — not CMM on every feature of every part. FAI and MTRs are available on request. Details: CNC machining quality control.
We welcome an NDA before you send CAD — email [email protected] or attach it with your RFQ. With a complete package we typically provide quote and DFM feedback within one business day. Contact us or Request a Quote.
