Technical Capabilities

CNC prototype machining is a high-precision subtractive manufacturing process used to produce functional prototypes with tight tolerances and complex geometries. At Honyo Prototype, we specialize in multi-axis milling and turning operations to meet demanding engineering requirements across a range of engineering-grade materials.

3/4/5-Axis Milling allows for the machining of complex 3D features with minimal setup. 3-axis is ideal for prismatic parts, while 4-axis (with rotational A-axis) and 5-axis (dual rotational axes) enable undercuts, angled features, and organic shapes without re-fixturing. CNC Turning is used for cylindrical or rotationally symmetric components, often in combination with milling for mill-turn parts.

All processes are optimized for tight tolerance machining, typically holding ±0.005 mm (±0.0002″) for critical dimensions, with surface finishes down to Ra 0.8 µm (32 µin) achievable.

Parameter	3-Axis Milling	4-Axis Milling	5-Axis Milling	CNC Turning
Max Work Envelope	1000 x 600 x 500 mm	800 x 500 x 400 mm	600 x 400 x 350 mm	Ø300 x 500 mm length
Positioning Accuracy	±0.005 mm	±0.005 mm	±0.005 mm	±0.005 mm
Repeatability	±0.003 mm	±0.003 mm	±0.003 mm	±0.003 mm
Typical Tolerance	±0.01 mm	±0.01 mm	±0.01 mm	±0.01 mm
Tight Tolerance Capability	±0.005 mm	±0.005 mm	±0.005 mm	±0.005 mm
Surface Finish (Typical)	Ra 1.6 – 3.2 µm	Ra 1.6 – 3.2 µm	Ra 0.8 – 1.6 µm	Ra 0.8 – 1.6 µm
Spindle Speed (Max)	24,000 rpm	20,000 rpm	20,000 rpm	6,000 rpm
Tool Changer Capacity	24 tools	24 tools	30 tools	12 stations

Compatible Materials:
Aluminum: 6061-T6, 7075-T6 – excellent machinability, high strength-to-weight ratio, ideal for aerospace and automotive prototypes.
Steel: 4140, 1018, Stainless 303/316 – high strength and wear resistance; suitable for high-load or corrosive environments.
ABS: Good impact resistance and dimensional stability; commonly used for functional plastic prototypes and fit-check models.
Nylon (PA6, PA66): High toughness, low friction, and good chemical resistance; used in wear-prone or structural plastic components.

All materials are machined using optimized toolpaths, high-precision carbide tooling, and in-process inspection (via CMM or probe) to ensure dimensional accuracy and repeatability. First-article inspection reports (FAIR) and material certifications are available upon request.

From CAD to Part: The Process

Honyo Prototype employs a streamlined, technology-driven workflow for CNC prototype machining designed to accelerate time-to-part while ensuring manufacturability and quality. Our defined process eliminates traditional bottlenecks through integrated digital tools and engineering expertise.

CAD Upload and Initial Processing
Clients initiate the process by uploading native or neutral format CAD files (STEP, IGES, Parasolid, SolidWorks) via our secure customer portal. The system performs immediate geometric validation, checking for file integrity, unit consistency, and basic topology errors. This step ensures the digital model is production-ready before proceeding to quotation, reducing downstream delays.

AI-Powered Quoting Engine
Uploaded geometry is processed by our proprietary AI quoting system, which analyzes part complexity, material requirements, machine time estimates, and fixture strategies. The algorithm cross-references real-time data from our machine shop floor, including current workload, tooling availability, and material stock levels. Clients receive a detailed quote with cost breakdown and estimated lead time within minutes, not days. The system flags potential high-risk geometries requiring immediate engineering review.

Engineer-Led DFM Analysis
Every project undergoes mandatory Design for Manufacturability (DFM) review by our senior CNC engineers, even after AI validation. This critical phase identifies opportunities to optimize geometry for machining efficiency, reduce secondary operations, and prevent costly errors. Key DFM considerations include:

DFM Factor	Analysis Focus	Typical Resolution
Feature Geometry	Undercuts, thin walls, deep cavities	Suggest draft angles, wall thickness adjustments
Tolerance Stack-Up	Interdependent GD&T callouts	Recommend relaxed tolerances where function allows
Material Utilization	Stock size vs. part envelope	Propose alternative billet dimensions
Setup Minimization	Feature accessibility	Redesign for single-setup machining

Engineers collaborate directly with clients to discuss findings, providing annotated CAD markups and formal DFM reports. Client approval is required before production release, ensuring alignment on any necessary design modifications.

Precision CNC Production
Approved designs move to our climate-controlled machine shop featuring 3-axis, 4-axis, and 5-axis milling centers alongside precision turning centers. Each job receives:
Material certification documentation for aerospace/medical grades
First-article inspection (FAI) per AS9102 standards for critical features
In-process CMM verification at defined checkpoints
Real-time production tracking via client portal with machine telemetry
Our closed-loop quality system captures tool wear compensation data and thermal drift corrections, maintaining ±0.005mm tolerances across production runs.

Logistics and Delivery
Completed prototypes undergo final cleaning, deburring, and protective coating as specified. Parts are packaged in anti-static foam within crush-resistant containers with humidity indicators. Every shipment includes:
Dimensional inspection report (PDF and physical copy)
Material traceability documentation
Process validation records
Certificate of Conformance
We offer global delivery via DHL/FedEx with real-time tracking, typically achieving 5-7 business day turnaround from DFM approval for standard prototypes. Expedited services (72-hour) are available for qualifying geometries. All deliverables include full digital traceability for audit compliance.
