Custom CNC Machining Process & OEM/ODM Workflow
Feiyu helps industrial buyers turn drawings, samples, and specifications into prototypes, production parts, inspected batches, and export-ready shipments.
This page explains what buyers should send, what Feiyu reviews, and how each manufacturing stage is controlled before shipment.
What Buyers Send / What Feiyu Provides
A clear RFQ package helps Feiyu check manufacturability, estimate cost, plan inspection, and respond with practical next steps.
Send These Details
2D drawings, 3D CAD files, or physical samples
Material, tolerance, surface finish, and inspection needs
Prototype quantity, batch quantity, or annual demand
Target lead time, packaging, and delivery requirements
Receive A Practical Plan
DFM feedback and process recommendation
Quotation, MOQ notes, and estimated production lead time
Prototype or sample validation plan when needed
QC checkpoints and delivery communication path
From RFQ To Repeat Production
The workflow is organized around buyer risk: confidentiality, manufacturability, sample approval, production control, inspection, and delivery.
Confidential Drawing Review
Feiyu can review drawings under NDA before discussing project details, samples, or proprietary specifications.
- IP protection
- Drawing and sample check
- Requirement confirmation
Engineering & Quotation
The team checks material, tolerance, geometry, surface finish, and process feasibility before quoting.
- DFM feedback
- Process selection
- Cost and lead-time review
Prototype Validation
Prototype or sample production helps buyers confirm fit, function, finish, and inspection requirements before scaling.
- Prototype machining
- Sample approval
- Revision feedback loop
Production Preparation
After approval, Feiyu prepares machining programs, tooling, material, fixtures, and inspection checkpoints.
- Tooling and fixtures
- Material planning
- Inspection route setup
Manufacturing & In-Process QC
Production teams control machining, fabrication, finishing coordination, assembly, and process inspection.
- CNC machining and fabrication
- Surface finish coordination
- Critical dimension checks
Final Inspection & Shipment
Finished parts are checked, packed, and prepared for export delivery with communication on shipment status.
- Final inspection
- Packing and labeling
- Export delivery support
How Feiyu Reduces Procurement Risk
The process is supported by real production, inspection, packaging, and communication steps that buyers can ask Feiyu to confirm during RFQ review.
Inspection Planning
Confirm critical dimensions, material requirements, surface finish, and report needs before production starts.
Production Tracking
Coordinate machining, fabrication, finishing, assembly, and batch communication through one factory team.
Export Readiness
Support packing, labeling, and shipment preparation from Ningbo for global industrial buyers.
Best-Fit Projects For This Workflow
This process is most useful for buyers who need custom industrial parts, repeat orders, multiple manufacturing steps, and reliable export communication.
Drawing-Based Components
Parts produced from drawings, CAD files, samples, material requirements, tolerance notes, and finish standards.
Prototype To Production
Projects where a buyer wants sample validation before moving into batch production or repeat orders.
Multi-Process Orders
Machining, fabrication, finishing, inspection, packaging, and delivery coordination through one supplier team.
Export-Oriented Buyers
International buyers who need clear communication, inspection checkpoints, and export packing support.
FAQ
Short answers for RFQ, sampling, production, inspection, and delivery questions.
What files should I send for quotation?
Send 2D drawings, 3D CAD files, material requirements, tolerance notes, surface finish, order quantity, inspection needs, and target lead time. Samples can also be reviewed when drawings are unavailable.
Can Feiyu sign an NDA before reviewing drawings?
Yes. Feiyu can support confidential drawing review before detailed engineering discussion, quoting, sampling, or production planning.
Does Feiyu provide DFM feedback?
Yes. Feiyu reviews material, tolerance, geometry, process feasibility, surface finish, and production risks before recommending a manufacturing route.
Can I approve samples before mass production?
Yes. Prototype or sample validation can be arranged before batch production when the project requires fit, function, finish, or tolerance confirmation.
What inspection information can be discussed?
Buyers can specify critical dimensions, inspection standards, material checks, surface finish requirements, packing checks, and final inspection documentation needs.
Send Drawings For Manufacturing Review
Share drawings, CAD files, material, tolerance, finish, quantity, and target timeline. Feiyu will review the process route and respond with practical next steps.
