Technical Capabilities

Technical Capabilities: Precision CNC Machining at Shenzhen Honyo Prototype

At Shenzhen Honyo Prototype, our CNC Auto Service delivers high-precision machining solutions tailored for rapid prototyping, low-volume production, and complex component manufacturing. Our advanced 3-axis, 4-axis, and 5-axis CNC milling centers, combined with multi-tasking turning centers, enable us to produce intricate geometries with consistent accuracy and superior surface finish. We specialize in tight-tolerance machining across a wide range of engineering materials, serving industries such as automotive, aerospace, medical, and industrial automation.

Our 3-axis milling is ideal for prismatic parts with straightforward geometries, offering fast turnaround and excellent dimensional control. When components require machining on multiple faces or complex contours, our 4-axis and 5-axis CNC systems provide enhanced flexibility by enabling rotary indexing and simultaneous multi-directional tool engagement. This reduces setup time, improves part accuracy, and allows for the production of highly complex features such as undercuts, organic surfaces, and angled mounting interfaces—all in a single setup.

For turned components, our CNC turning centers support both bar-fed and chucking operations, handling parts up to 300 mm in diameter and 600 mm in length. We integrate live tooling for mill-turn capabilities, allowing us to produce fully finished turned-milled components without secondary operations. This hybrid approach ensures tight concentricity and optimal cycle efficiency.

Tight-tolerance machining is a core competency at Honyo. We routinely hold tolerances down to ±0.005 mm on critical dimensions, with positional tolerances as tight as ±0.01 mm. Our metrology suite includes high-accuracy CMMs, optical comparators, and laser measurement systems, ensuring every component meets specified tolerances before shipment. Process validation is performed through first-article inspection reports (FAIR) and production part approval processes (PPAP) when required.

We support a broad spectrum of materials, including aluminum alloys (6061, 7075), stainless steels (303, 304, 316), carbon steels, titanium (Grade 5), brass, copper, and high-performance engineering plastics such as PEEK, PTFE, and Delrin. Material selection is optimized based on functional requirements, environmental exposure, and machinability to ensure both performance and cost-efficiency.

The following table outlines our standard machining capabilities and tolerance ranges:

| Parameter | 3-Axis Milling | 4-Axis Milling | 5-Axis Milling | CNC Turning |

|—————————-|———————-|———————-|———————-|———————-|

| Max Work Envelope (mm) | 1000 × 600 × 500 | 800 × 600 × 500 | 600 × 600 × 500 | Ø300 × 600 |

| Standard 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 (Ra) | 0.8 – 3.2 µm | 0.8 – 3.2 µm | 0.8 – 3.2 µm | 0.8 – 1.6 µm |

| Positional Accuracy | ±0.01 mm | ±0.01 mm | ±0.01 mm | ±0.01 mm |

We also provide secondary operations including deburring, anodizing, plating, passivation, and precision cleaning to meet application-specific requirements. With integrated CAD/CAM programming and real-time process monitoring, Shenzhen Honyo Prototype ensures repeatability, quality, and on-time delivery for every CNC auto service project.

From CAD to Part: The Process

CNC Machining Production Process: From CAD to Precision Part

Shenzhen Honyo Prototype delivers rapid, high-precision CNC machined prototypes through a rigorously defined workflow. This integrated process, spanning AI-driven quoting to final part production, ensures manufacturability, cost efficiency, and adherence to stringent quality standards from the initial CAD model. Our systematic approach minimizes iteration cycles and accelerates time-to-part for demanding B2B applications.

The workflow commences with the AI-Powered Quoting Engine. Upon secure upload of the client’s native CAD file (STEP, IGES, Parasolid, or native formats like SOLIDWORKS), our proprietary cloud-based AI platform performs an instant geometric and material analysis. This system evaluates key parameters including part volume, feature complexity, required axes, material stock utilization, and estimated machine time. Crucially, the AI provides immediate feedback on fundamental manufacturability flags, such as excessively thin walls below 0.5mm or deep cavities exceeding standard tool reach, alongside a highly accurate preliminary cost and lead time estimate. This initial step empowers clients with rapid feasibility insight before formal commitment.

Following client confirmation, the project enters the critical Design for Manufacturability (DFM) Review phase. Our senior manufacturing engineers conduct a detailed manual assessment, building upon the AI’s initial findings. This collaborative stage involves direct consultation with the client’s design team to optimize the part for CNC production. Engineers evaluate feature accessibility, optimal stock size selection, strategic datum placement, tolerance stack-up feasibility, and opportunities to simplify geometry without compromising function. Specific recommendations might include adjusting internal corner radii to match standard end mill sizes, modifying wall thicknesses for stability, or suggesting alternative hole depths to avoid custom tooling. Client approval of the DFM report is mandatory before proceeding, ensuring alignment on any design refinements necessary to achieve target quality and cost.

With the finalized DFM-approved design, the project advances to Precision CNC Production. Our state-of-the-art facility utilizes multi-axis machining centers (3-axis, 4-axis, and 5-axis) from leading OEMs, equipped with high-precision spindles and automated tool changers. Machinists generate optimized CNC programs using Mastercam and Fusion 360, incorporating proven cutting strategies and toolpaths validated for specific materials. Production strictly adheres to the approved DFM specifications and geometric dimensioning and tolerancing (GD&T) callouts. In-process inspections using calibrated CMMs and optical comparators verify critical features at defined checkpoints, ensuring dimensional accuracy throughout the machining sequence. Final parts undergo comprehensive 100% dimensional inspection against the original CAD model and surface finish verification before packaging and shipment.

This seamless integration of AI intelligence, expert engineering judgment, and advanced manufacturing execution guarantees that every prototype part meets Honyo Prototype’s exacting standards for precision, repeatability, and on-time delivery. The structured workflow inherently minimizes costly rework and design revisions, providing clients with a reliable, transparent path from digital concept to physical reality.

Key production capabilities for common prototype materials are summarized below:

| Parameter | Typical Capability (Aluminum 6061-T6 Example) | Notes |

| :—————– | :——————————————– | :————————————- |

| Standard Tolerance | ±0.025 mm (±0.001″) | Tighter tolerances achievable per GD&T |

| Surface Finish | Ra 1.6 µm (63 µin) standard | Down to Ra 0.4 µm (16 µin) possible |

| Max Work Envelope | 1000 x 600 x 500 mm | For 5-axis machining centers |
