Technical Capabilities

Honyo Prototype offers high-precision custom machining services in China, specializing in multi-axis CNC milling and turning operations for demanding industrial and engineering applications. Our advanced manufacturing capabilities support tight tolerance requirements and a wide range of engineering materials including aluminum, steel, ABS, and nylon.

The following table outlines the key technical specifications for our custom machining services:

Parameter	Specification
Machining Types	3-Axis, 4-Axis, and 5-Axis CNC Milling; CNC Turning (2-axis and multi-axis)
Positioning Accuracy (Milling)	±0.005 mm
Repeatability (Milling)	±0.002 mm
Tolerance Capability	As tight as ±0.005 mm (±0.0002″) for critical features
Surface Finish (Typical)	Ra 0.8 μm (32 μin) standard; down to Ra 0.2 μm (8 μin) with polishing options
Maximum Work Envelope (Milling)	1000 mm × 600 mm × 500 mm (X-Y-Z)
Maximum Turning Diameter	300 mm
Maximum Turning Length	500 mm
Spindle Speed (Milling)	Up to 24,000 RPM (high-speed options available)
Tooling System	Automatic tool changers (ATC), ISO 30 or BT30 interface
Materials Supported	Aluminum (6061, 7075, 2024), Steel (1018, 4140, Stainless 303/304/17-4 PH), ABS, Nylon (PA6, PA66), and other engineering plastics
Quality Standards	ISO 2768-m, ISO 2768-f (custom GD&T per drawing)
Inspection Equipment	CMM, optical comparators, micrometers, bore gauges, surface roughness testers
Lead Time (Typical)	5–15 days depending on complexity and volume

Our 5-axis simultaneous machining centers enable complex contouring and single-setup machining of intricate geometries, reducing part handling and improving dimensional consistency. Tight tolerance features such as precision bores, threaded inserts, and critical alignment surfaces are routinely held within ±0.01 mm. Material-specific toolpaths and optimized cutting parameters ensure superior surface integrity and part performance across both metals and engineering plastics.

All processes are supported by full CAD/CAM integration and first-article inspection reporting (FAIR), making Honyo Prototype a trusted partner for prototypes and low-to-medium volume production runs requiring high repeatability and technical precision.

From CAD to Part: The Process

Honyo Prototype Custom Machining Process Overview
Honyo Prototype executes a streamlined, technology-driven workflow for custom machining projects originating from global clients. Our China-based manufacturing hub in Shenzhen integrates advanced digital tools with precision CNC capabilities to ensure rapid turnaround without compromising quality. The end-to-end process follows five rigorously defined phases.

CAD File Submission
Clients initiate the process by uploading native or neutral CAD formats (STEP, IGES, Parasolid, SolidWorks) via our secure customer portal. The system validates file integrity, confirms geometric completeness, and performs an initial material compatibility check against our approved stock database. All data transmission adheres to ISO 27001 security protocols with client-specific encryption.

AI-Powered Quoting Engine
Uploaded geometry triggers our proprietary AI quotation system trained on 50,000+ historical machining projects. The algorithm analyzes 127 geometric parameters including feature complexity, tolerance density, and setup requirements. It cross-references real-time data on machine availability, material costs from certified Chinese mills, and labor rates to generate a binding quote within 90 minutes. Critical outputs include cost breakdown, lead time projection, and preliminary manufacturability flags.

Integrated DFM Analysis
Before order confirmation, our engineering team conducts a formal Design for Manufacturability review. This phase merges AI-generated insights with human expertise to identify optimization opportunities. Key focus areas include:

DFM Category	Specific Checks	Typical Resolution Time
Geometric Feasibility	Undercuts, thin walls, cavity depth-to-width ratios	< 4 business hours
Tolerance Optimization	Over-specified GD&T, cumulative stack-up risks	< 6 business hours
Material Efficiency	Stock size alignment, chip load considerations	< 2 business hours

Engineers collaborate directly with clients to implement modifications, providing annotated 3D markups and alternative design suggestions. Only upon client approval of the DFM report does the project advance.

Precision Production Execution
Manufacturing occurs in our ISO 9001:2015 certified Shenzhen facility using Haas and DMG MORI CNC centers with 5-axis capability. Each run includes:
Material certification traceability from Chinese mills meeting ASTM/GB standards
In-process CMM validation at critical stages per AS9100 inspection plans
Real-time machine monitoring for tool wear and thermal compensation
Dedicated project managers providing weekly production dashboards

Average lead time from DFM sign-off to shipment completion is 8-12 business days for 1-50 piece quantities, depending on complexity.

Global Logistics Management
Finished components undergo final first-article inspection against all client-specified requirements. We manage door-to-door delivery via DHL/FedEx with:
Climate-controlled packaging meeting IPC-1601 standards
Digital customs documentation pre-submission
Real-time shipment tracking integrated into client ERP systems
100% on-time delivery performance for projects under 200kg in Q3 2024

This closed-loop process reduces prototyping iterations by 63% versus industry averages while maintaining ±0.005mm tolerance capability across aluminum, steel, titanium, and engineering plastics. All production data remains accessible via client portal for future revision tracking.
