This makes China a competitive global hub for high-precision CNC machining services.
From CAD to Part: The Process

Honyo Prototype Precision Machining Process Overview
Our end-to-end precision machining workflow for global clients leverages China-based manufacturing capabilities while maintaining rigorous international quality standards. The process is engineered for speed, accuracy, and transparency, eliminating traditional supply chain friction.
Stage 1: CAD Upload and System Integration
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid) via our secure customer portal. The system automatically validates file integrity, extracts geometric and material requirements, and flags potential ambiguities such as missing tolerances or surface finish callouts. This phase ensures all technical data is structured for downstream AI analysis within 15 minutes of submission.
Stage 2: AI-Powered Quoting Engine
Honyo’s proprietary AI engine analyzes the CAD geometry against real-time production parameters including machine availability, material costs, and labor rates at our Shenzhen facility. The algorithm cross-references historical production data from 12,000+ completed projects to generate a detailed quote within 2 business hours. Quotes include cost breakdowns by operation (milling, turning, grinding), material waste calculations, and a preliminary timeline. Unlike manual quoting, our system reduces estimation variance to under 3% by accounting for micro-factors like toolpath complexity and fixturing requirements.
Stage 3: Collaborative DFM Analysis
Upon quote acceptance, our engineering team conducts a formal Design for Manufacturing review. This is not a pass/fail gate but an iterative collaboration:
Geometric feasibility assessment against 5-axis milling/turning capabilities (±0.001mm tolerance standard)
Material suitability verification per ASTM/GB standards with substitution recommendations if needed
Cost-optimization suggestions (e.g., tolerance relaxation on non-critical features)
Rapid virtual prototyping via CNC simulation software to identify collisions or inefficiencies
Clients receive a marked-up DFM report with actionable revisions within 24 hours, typically reducing manufacturable lead times by 15-30%.
Stage 4: Production Execution
Approved designs move to our ISO 9001:2015 and AS9100D-certified facility in Shenzhen. Key production metrics:
| Process Parameter | Capability | Quality Control Method |
|---|---|---|
| Tolerance Range | ±0.001mm to ±0.05mm | CMM inspection (Zeiss CONTURA) |
| Material Types | Metals (Al, Ti, SS), Engineering Plastics, Composites | Material Certificates (MTR/COA) |
| Equipment | DMG MORI 5-axis, Tsugami Swiss-type | Real-time tool wear monitoring |
| Batch Sizes | 1-500 units | First-article inspection (FAI) per AS9102 |
All critical dimensions undergo in-process verification using Renishaw probes, with full traceability via serialized work orders. Production data is updated hourly in the client portal.
Stage 5: Global Logistics and Delivery
Finished parts undergo final QA per the client’s blueprint before packaging in ESD-safe containers. Our integrated logistics system provides:
DDP (Delivered Duty Paid) shipping options via DHL/FedEx with carbon-neutral routing
Real-time GPS tracking from Shenzhen warehouse to destination
Digital delivery certification including inspection reports and material traceability
Standard lead time from DFM approval to delivery is 7-12 business days for most metal components, with 99.2% on-time delivery performance in 2023. Critical shipments include expedited air freight coordination managed through our Hong Kong logistics hub.
This closed-loop process ensures technical rigor at every stage while leveraging China’s manufacturing ecosystem for competitive pricing. The integration of AI-driven quoting with human engineering oversight eliminates traditional prototyping bottlenecks, delivering precision-machined components with documented quality for aerospace, medical, and industrial sectors.
