Custom Precision CNC Machining Services

Multi-Process Precision CNC Machining Under One Roof

When your project demands more than a single machining operation, coordinating multiple suppliers introduces delays, tolerance stack-up errors and accountability gaps. Our precision CNC machining service combines turning, milling, drilling, tapping and finishing in one IATF 16949 certified facility, eliminating handoff friction and giving you a single point of accountability from drawing to delivery.

What We Machine

• Shafts and pins: CNC turned with IT6-IT7 tolerance, ground finishes available
• Mounting plates and brackets: CNC milled with tight flatness and perpendicularity
• Bushings and sleeves: Turned and bored with H7 tolerance bores
• Threaded components: Tapped, threaded and chamfered in a single setup
• Sub-assemblies: Press-fit pins, inserted bearings and ready-to-install units

Why Buyers Choose Consolidated Machining

Importers and EPC contractors frequently face the challenge of managing 5-10 suppliers for a single assembly. By consolidating multi-process machining at ChunTian, you gain:

• Single-source traceability: One FAI package, one CMM report set, one QC photo pack for the entire assembly
• Reduced tolerance stack-up: Critical datums machined in the same setup, not accumulated across suppliers
• Shorter lead time: No inter-supplier shipping, no queue delays at multiple shops
• Consistent quality system: IATF 16949:2016 applied uniformly across every operation

Materials We Commonly Machine

Carbon steel (C45, Q235), stainless steel (304, 316), aluminum (6061, 6063, 7075), brass, copper, and engineering plastics (PEEK, POM, nylon). Material certificates (3.1 or 2.2) available on request.

Quality Documentation Package

Every production run ships with a structured documentation set:

• Drawing review notes with tolerance risk flags
• First-article inspection (FAI) report with CMM data
• In-process SPC charts for critical dimensions
• Final inspection checklist with dimensional sign-off
• Material test certificates
• QC photo pack showing key stages and packing

Buyer FAQ

Q: Can you handle both prototype and volume production?
Yes. We run prototype lots for design validation and scale to volume production with documented process control.

Q: Do you provide CMM inspection reports?
Yes, CMM reports are included for critical dimensions. Additional inspection plans can be tailored to your requirements.

Q: Can you machine to custom drawings?
Absolutely. Send your drawings (STEP, IGES, DWG or PDF) and we will review them for manufacturability before quoting.
