Technical Capabilities
Honyo Prototype delivers high-precision machining services meeting stringent aerospace standards, with technical capabilities centered on multi-axis CNC milling and turning for mission-critical components. Our 3-axis, 4-axis, and 5-axis CNC machining platforms are optimized for complex geometries, tight tolerances, and repeatable accuracy required in aerospace applications. We specialize in machining a range of materials including aluminum alloys (e.g., 6061-T6, 7075-T6), alloy steels (e.g., 4140, 17-4 PH), and high-performance polymers such as ABS and nylon (e.g., PA6, PA66), ensuring compatibility with both structural and non-metallic aerospace requirements.
The following table outlines the key technical specifications for our aerospace precision machining services:

All processes adhere to ISO 9001 and AS9100 quality management standards. Materials are certified and traceable, with full inspection reporting (FAI/PPAP available). 5-axis machining enables single-setup production of complex contours and deep cavities, reducing cumulative error and improving geometric accuracy. Tight tolerance capabilities are maintained through thermal compensation, in-process probing, and post-machining CMM verification using Zeiss or Hexagon metrology systems.
For polymer components such as ABS and nylon, we apply optimized cutting strategies, low-stress fixturing, and environmental controls to minimize deformation and ensure dimensional stability.
From CAD to Part: The Process
Honyo Prototype delivers China-based aerospace precision machining through a rigorously controlled workflow designed for mission-critical components. Our process integrates advanced technology with deep domain expertise to ensure compliance, quality, and on-time delivery for demanding aerospace applications.
Upload CAD
Clients initiate the process by securely uploading native or neutral CAD files (STEP, IGES, Parasolid) via our encrypted portal. For aerospace projects, we specifically request associated GD&T callouts, material specifications per AMS/ASTM standards, and any applicable drawing notes referencing ASME Y14.5 or aerospace-specific standards. Our system automatically checks file integrity and geometry complexity, flagging potential issues like non-manufacturable features before proceeding.
AI-Powered Quoting
Our proprietary AI engine analyzes the CAD geometry, material requirements, and tolerance stack-ups to generate an initial quote within 24 hours. The AI cross-references real-time data on titanium alloys (e.g., Ti-6Al-4V), Inconel 718, and aluminum aerospace grades, incorporating current raw material costs from certified Chinese mills. Crucially, the AI identifies high-risk features requiring specialized tooling or inspection—such as deep cavities with ±0.005mm tolerances—and factors in NADCAP-accredited process costs. A Senior Manufacturing Engineer validates all AI outputs, adding notes on feasible lead time reductions or critical process controls.
DFM Analysis
Honyo’s aerospace-dedicated DFM team conducts a 72-hour deep dive using Siemens NX CAM. We focus on aerospace-specific optimizations:
Material waste reduction for expensive alloys while maintaining forging grain flow orientation
Machining sequence validation for thin-walled structures to prevent distortion
Critical feature accessibility assessment for 5-axis milling of complex contours
Surface finish and residual stress mitigation strategies for fatigue-critical parts
The DFM report includes actionable recommendations with tolerance relaxation options per AS9100 clause 8.5.1, always preserving functional requirements. Clients receive a collaborative review session with our NADCAP-certified process engineers.
Production Execution
Manufacturing occurs in our ISO 14644 Class 7 cleanroom facility in Chengdu, featuring:
5-axis DMG MORI machines with integrated Renishaw probing for in-process verification
Vacuum induction melting (VIM) sourced materials with full material test reports (MTRs)
Real-time SPC monitoring of critical dimensions using Zeiss Calypso CMMs
Every operation follows documented work instructions aligned with AS9100 Rev D. For titanium components, we implement strict oxygen-level controls during machining to prevent contamination. First-article inspections include full FAI per AS9102 with 3D scan overlays against nominal CAD.
Delivery and Documentation
Final delivery includes the components in ESD-safe packaging with traceability tags linking to:
| Document Type | Aerospace Requirement | Honyo Implementation |
