China CNC machining factory for custom parts, prototypes, and low-volume production
Upload your 2D drawings or 3D CAD files and get a manufacturability-focused quote from a China-based CNC machining factory. We support CNC milling, CNC turning, metal and plastic parts, DFM review, inspection, and export packaging for overseas buyers.

CNC Milling
Complex profiles, pockets, slots, plates, housings, brackets, and fixture parts.
CNC Turning
Shafts, bushings, spacers, threaded parts, pins, and round precision components.
Prototype + Low Volume
Useful for engineering validation, pilot runs, replacement parts, and bridge production.
DFM Review
Drawing review before quote so buyers can clarify tolerances, material, finish, and quantity.
Know what to send before you request a CNC quote
Strong CNC quote pages reduce uncertainty before the form. Use this homepage to prepare the files and manufacturing details that affect price, lead time, machinability, and inspection risk.
Files that speed up review
Send a 3D model for geometry, a 2D drawing for tolerances and threads, and notes for material, finish, quantity, delivery country, and inspection requirements.
What the factory checks before quoting
The review focuses on machinability, tolerance risk, material availability, surface finish, fixture needs, critical features, and avoidable cost drivers before production is confirmed.
Tolerances
Mark fit-critical dimensions clearly instead of over-specifying every feature.
Material grade
State the alloy, plastic grade, or acceptable equivalent standard where possible.
Surface finish
Mention as-machined, anodizing, plating, passivation, polishing, or other required finish.
Inspection needs
Tell the factory if dimensional reports, material documents, or packaging notes are required.
Clear manufacturing information before you send an RFQ
Engineers
Check whether the material, tolerance, finish, and geometry are suitable before release.
Procurement Teams
Send drawings, quantities, and delivery requirements to compare practical machining quotes.
Hardware Startups
Move from prototype validation to short-run production without changing suppliers too early.
From your drawing to your parts in three steps
Prototype and small-batch RFQs are welcome. Engineering review is based on your drawings, material, finish, and quantity requirements.
Upload Your Drawing
Send 3D CAD (STEP/STP/IGS/SLDPRT) plus a 2D drawing with tolerances and finish notes.
DFM Review & Quote
An engineer checks machinability and cost drivers. You receive quote feedback after your drawing and requirements are reviewed.
Parts Delivered
Prototype lead time depends on material, geometry, surface finish, and order quantity. Inspection checks can be added based on project requirements.
Factory-direct CNC support for overseas custom part buyers
Direct manufacturing communication
Discuss drawings, quantities, material options, surface finish, and inspection requirements with a production-focused team.
Prototype to batch transition
Use early samples to validate fit and function, then request low-volume or batch machining when the design is stable.
Export-oriented quoting
RFQs can include destination country, packaging needs, lead time target, and documentation requirements.
Cost-conscious engineering
DFM feedback can help reduce unnecessary machining time, difficult features, or over-specified tolerances.
Machining services for custom metal and plastic parts
Services
CNC milling, CNC turning, prototype machining, low-volume production, batch machining support, and drawing-based custom part manufacturing.
Materials
Common RFQ materials include aluminum, stainless steel, carbon steel, brass, copper, engineering plastics, and other specified materials.
File formats
Send STEP, STP, IGS, IGES, X_T, SLDPRT, DXF, DWG, PDF, or other available manufacturing drawings for review.
Quote details
For faster quoting, include material, quantity, key tolerances, surface finish, threaded features, lead time target, and shipping country.
Quick check before you upload a CNC drawing
Use this overview to decide whether your custom part is a practical RFQ fit. Final confirmation depends on the drawing, material, quantity, tolerance, finish, and inspection requirements.
CNC machined parts for these industries
Jigs, fixtures, mounting plates, machine components
Structural brackets, joints, end-effector parts
Housings, heat sinks, panels, connector bodies
Prototype and aftermarket components
Functional prototypes, design iterations, pre-production runs
Non-implant fixtures, housings, and instrument components where requirements are confirmed.
From drawing upload to inspected CNC parts
Upload drawing
Send 2D/3D files with material, quantity, and finish notes.
DFM review
The drawing is checked for machinability and quote-critical details.
Quote
Receive pricing based on geometry, tolerance, material, process, and quantity.
Machining
Prototype, low-volume, or batch parts are machined after confirmation.
Inspection
Parts are checked, packed, and prepared for international delivery.
Quote with the details that affect machining quality
Good CNC quotes depend on more than part geometry. Critical dimensions, tolerance callouts, material grade, surface finish, threads, inspection points, and packaging expectations all affect price and delivery risk.
Tolerance review
Avoid over-specifying non-critical features; call out dimensions that affect fit or function.
Material confirmation
Specify grade or equivalent standard where possible to avoid sourcing ambiguity.
Inspection before shipment
Request dimensional checks or reports when your project requires documented verification.
Before you request a CNC machining quote
What files should I send?
Send 3D CAD files such as STEP/STP or IGS/IGES when available, plus 2D drawings or PDFs for tolerances, threads, finishes, and inspection notes.
Can you quote prototypes and small batches?
Yes. This homepage is structured for prototype, low-volume, and batch CNC RFQs. Final feasibility depends on drawing, material, quantity, tolerance, and finish.
What should I include in the RFQ?
Include material, quantity, target lead time, delivery country, critical tolerances, surface finish, and any inspection or packaging requirements.
Can I request a DFM review?
Yes. Use the RFQ CTA to send your drawing and ask for manufacturability feedback before confirming production.
How are my drawings handled?
Drawing files are used for RFQ review and project communication. If your project requires confidentiality terms or an NDA process, mention it before sharing sensitive files so the requirement can be reviewed first.
Request a CNC machining quote for your custom part
Share your drawing files, material, quantity, and delivery requirements. A complete RFQ helps the factory review manufacturability, quote accurately, and reduce back-and-forth before machining.
