All custom CNC machining projects in China are supported by full process documentation, GD&T interpretation, and engineering review to ensure compliance with demanding design requirements. Tight tolerance features such as precision bores, thin walls, and complex contours are routinely held within specification using high-stability tooling and proven fixturing strategies.
From CAD to Part: The Process
Honyo Prototype executes China custom CNC machining through a rigorously defined workflow designed for speed, precision, and risk mitigation. This integrated process ensures manufacturability while maintaining strict adherence to international quality standards for global B2B clients.
Upload CAD
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid) via our secure customer portal. Our system validates file integrity and geometric completeness, rejecting submissions with critical errors like unsealed surfaces or missing datums. This step establishes the foundational geometry for all downstream operations, with automated checks ensuring compatibility with ISO 10283 tolerance standards.
AI Quote
Within 72 hours, Honyo’s proprietary quoting engine generates a binding price and lead time estimate. This AI system dynamically analyzes CAD geometry against real-time variables:
Current machine utilization across our Dongguan and Shenzhen facilities
Live material pricing from certified Chinese suppliers (AISI 304, 7075-T6, POM, etc.)
Geometric complexity metrics (feature count, cavity depth ratios, thin-wall detection)
Secondary operation requirements (anodizing, precision tapping)
The output includes a detailed cost breakdown table validated by senior manufacturing engineers before client release.
| Cost Component | Calculation Basis | Transparency Level |
|---|---|---|
| Raw Material | Weight × Live market rate + 5% waste factor | Full visibility |
| Machine Time | Spindle hours × Facility-specific rate card | Itemized per setup |
| Finishing | Surface area × Process complexity multiplier | Per-operation |
| QA Documentation | Fixed cost based on AS9102 or PPAP requirements | Explicit line item |
DFM
All projects undergo mandatory Design for Manufacturability review by Honyo’s China-based engineering team. This phase identifies critical issues such as:
Non-optimal wall thickness for specified materials below 0.8mm
Tool access limitations in deep cavities exceeding 10:1 aspect ratios
Tolerance stack-up risks in multi-axis setups
Cost drivers like unnecessary tight tolerances (±0.005mm vs achievable ±0.025mm)
Clients receive a formal DFM report with actionable revision recommendations, typically resolving 92% of manufacturability issues before production begins. This step reduces scrap rates by 37% compared to direct-to-machine workflows.
Production
Machining occurs in Honyo’s ISO 9001-certified facilities using HAAS and DMG MORI equipment. Key protocols include:
First-article inspection against CAD using Zeiss CONTURA CMMs
In-process checks at critical stages (e.g., after roughing, semi-finishing)
Real-time SPC monitoring of dimensional drift on critical features
Material traceability via laser-etched batch codes matching mill certificates
All operations follow documented work instructions compliant with IATF 16949 standards, with full production logs accessible via client portal.
Delivery
Honyo manages end-to-end logistics with DDP (Delivered Duty Paid) terms as standard. This includes:
Consolidated shipment preparation with customs-compliant documentation
Real-time container tracking from Shenzhen port to final destination
Final inspection reports (FAIR) packaged with parts
Automated delivery notifications with ETA updates
Typical lead time from CAD upload to EXW delivery is 15–20 business days for complex multi-part assemblies, with 99.2% on-time performance in Q1 2024. All shipments include material certifications, process validation records, and non-conformance reports if applicable, ensuring full audit readiness for regulated industries.
