Technical Capabilities

CNC machined aluminum components are manufactured using advanced 3-axis, 4-axis, and 5-axis milling systems, as well as precision CNC turning centers. These processes enable high accuracy, complex geometry, and tight tolerance capabilities essential for aerospace, medical, automotive, and industrial applications. The following table outlines the technical specifications related to CNC machining services with a focus on aluminum, while also including comparative data for steel, ABS, and nylon.

Parameter	Aluminum (6061, 7075)	Steel (4140, 1018, 304SS)	ABS (Acrylonitrile Butadiene Styrene)	Nylon (PA6, PA66)
Machining Process	3-axis, 4-axis, 5-axis milling, CNC turning	3-axis, 4-axis, 5-axis milling, CNC turning	3-axis, 4-axis milling, CNC turning	3-axis, 4-axis milling, CNC turning
Typical Tolerance	±0.0005″ (12.7 µm)	±0.0005″ (12.7 µm)	±0.001″ (25.4 µm)	±0.001″ (25.4 µm)
Tight Tolerance Capability	Up to ±0.0002″ (5 µm) with process control	Up to ±0.0002″ (5 µm) with process control	±0.001″ typical; not recommended for ultra-tight tolerances	±0.001″ typical; moisture absorption affects dimensional stability
Surface Finish (Typical)	32–64 µin Ra (as-machined), down to 16 µin Ra with polishing	32–64 µin Ra, down to 16 µin Ra with finishing	64–125 µin Ra	64–125 µin Ra
Common Grades Used	6061-T6, 7075-T6, 2024, 5052	4140, 1018, 304/316 Stainless Steel	ABS-M30, ABSplus	PA6, PA66, Glass-filled Nylon
Material Properties	Lightweight, high strength-to-weight ratio, excellent machinability, good corrosion resistance	High strength, wear resistance, suitable for high-stress applications	Good impact resistance, low cost, easy to machine	High toughness, wear resistance, low friction; hygroscopic
Applications	Aerospace components, heat sinks, enclosures, prototypes	Shafts, fixtures, tooling, structural parts	Prototypes, housings, jigs, non-structural parts	Gears, bushings, wear strips, structural components
Secondary Operations	Anodizing (Type II & III), bead blasting, polishing, passivation, laser engraving	Plating (Zn, Ni), passivation, heat treatment, painting	Vapor polishing, painting, assembly	Annealing (to reduce stress), dyeing, machining post-forming

All CNC machining operations are supported by CAD/CAM programming, in-process inspection (CMM, micrometers, optical comparators), and full documentation for quality assurance. 5-axis milling enables single-setup machining of complex contours and undercuts, improving repeatability and reducing lead time. Tight tolerance work requires environmental control, tool wear monitoring, and iterative inspection, particularly for aluminum and steel components. ABS and nylon are generally used for prototyping or low-stress environments where metal-like precision is not required.

From CAD to Part: The Process

Honyo Prototype CNC Machined Aluminum Process Flow

Our end-to-end process for CNC machined aluminum components begins with seamless digital integration and concludes with certified delivery, ensuring precision and efficiency for engineering clients.

Upload CAD
Clients initiate the process by uploading native or neutral CAD formats (STEP, IGES, Parasolid, or native SOLIDWORKS) via our secure client portal. We require complete geometric definitions, specified material grade (e.g., 6061-T6, 7075-T6), surface finish requirements, and critical tolerances. Incomplete submissions trigger an automated notification for revision prior to quote generation, minimizing downstream delays.

AI-Powered Quoting
Uploaded CAD data undergoes automated analysis by our proprietary AI engine, which evaluates geometric complexity, feature density, stock utilization, and machine time requirements. The system cross-references real-time material costs, machine availability, and labor rates to generate a preliminary quote within 2 hours. Crucially, this stage includes an initial manufacturability risk flag—such as thin walls below 0.5mm or deep cavities exceeding 10:1 aspect ratios—alerting both client and Honyo engineers before formal commitment.

Engineer-Validated DFM
All quotes enter mandatory Design for Manufacturability review by our senior CNC engineering team. We conduct a detailed analysis using Mastercam and Vericut simulations to identify: tool access constraints, optimal stock dimensions, fixture requirements, and secondary operation needs. Clients receive a formal DFM report within 24 hours highlighting actionable recommendations—such as modifying non-critical radii to standard tool sizes or adjusting hole depths to avoid custom drill lengths—with direct markup on their original CAD. This phase reduces production revisions by 73% based on 2023 client data.

Precision Production
Approved designs move to production in our ISO 9001:2015-certified facility. Aluminum stock is verified for mill certificates and batch-traceable material properties prior to machining. Components are manufactured on HAAS and DMG MORI 3-5 axis CNC centers with in-process CMM validation at critical stages. For tight-tolerance features (e.g., ±0.025mm), we implement thermal compensation protocols and post-process verification on Zeiss CONTURA CMMs. All operations adhere to documented work instructions with full digital traceability.

Certified Delivery
Completed parts undergo final inspection per AS9102 first-article requirements when specified, with full FAIR documentation available. Components are cleaned, passivated (for aerospace-grade alloys), and packaged in anti-corrosive VCI film with humidity indicators. Delivery includes:
Dimensional report with actual vs. nominal measurements
Material certification
Process non-conformance log (if applicable)
Digital as-built model for client validation
Standard lead time is 7-10 business days from DFM approval, with expedited 72-hour options for qualifying geometries.

Tolerance Capability Reference
| Feature Type | Standard Capability | Precision Capability |
|——————–|———————|———————-|
| Linear Dimensions | ±0.1 mm | ±0.025 mm |
| Holes (Drilled) | ±0.05 mm | ±0.01 mm |
| Surface Roughness | Ra 3.2 μm | Ra 0.8 μm |
| Flatness | 0.1 mm | 0.025 mm |

This integrated workflow ensures clients receive production-ready aluminum components with minimized risk, validated quality, and full transparency from digital model to physical part. Our closed-loop system reduces time-to-prototype by 40% compared to industry averages while maintaining strict compliance with aerospace, medical, and automotive specifications.
