Technical Capabilities

CNC machining for medical applications requires high precision, repeatability, and compliance with regulatory standards due to the critical nature of medical devices and components. 3-axis, 4-axis, and 5-axis milling, along with CNC turning, are commonly used to manufacture complex geometries, implants, surgical instruments, and diagnostic equipment. These processes support tight tolerances typically ranging from ±0.0002″ to ±0.001″, depending on design requirements and material behavior. Below is a summary of key technical specifications relevant to CNC machining in the medical sector.

Feature	3-Axis Milling	4-Axis Milling	5-Axis Milling	CNC Turning
Axis Movement	X, Y, Z linear axes	X, Y, Z + A (rotary around X)	X, Y, Z + A and B (rotary)	X, Z linear + C (spindle rotation)
Typical Tolerance	±0.0005″ (12.7 µm)	±0.0004″ (10.2 µm)	±0.0002″ to ±0.0005″ (5–12.7 µm)	±0.0003″ (7.6 µm)
Surface Finish (Ra)	32–125 µin	32–63 µin	16–32 µin (achievable with polishing)	16–63 µin
Common Materials	Aluminum 6061, 7075; Stainless Steel 316L, 17-4 PH; ABS, Nylon 6, Nylon 6/6	Same as 3-axis, with improved access for complex shapes	Same, optimized for intricate 3D contours	Same, ideal for cylindrical and symmetrical parts
Applications	Flat or prismatic parts, enclosures, brackets	Indexing features, drilling at angles, multi-sided parts	Implants (e.g., knee, hip), surgical guides, complex housings	Shafts, fittings, threaded components, instrument tips
Material Suitability	Aluminum: Excellent	Steel: Good (requires rigid setup)	ABS: Good (low heat)	Nylon: Moderate (chip control)
	Steel: High strength, biocompatible options (316L, 440C)	ABS: Limited to non-implant, low-stress	ABS: Limited to non-load-bearing	Aluminum: High machinability
	ABS: Low cost, for prototypes	Nylon: Wear-resistant, biocompatible grades available	Nylon: Used in jigs, non-sterile tools	Steel: Preferred for durability and sterilization
Key Advantages	Fast for simple geometries	Adds rotational indexing for complex features	Full contouring, minimal setups, high accuracy	High precision on round parts, efficient for high volumes
Compliance Considerations	ISO 13485, FDA 21 CFR Part 820, biocompatibility (ISO 10993) for implantable materials	Same	Same	Same

All medical CNC machined components must be produced in controlled environments, often with full traceability of materials and process documentation. Post-machining processes such as passivation (for stainless steel), electropolishing, and cleanroom assembly may be required depending on the application. The selection of 3, 4, or 5-axis milling versus turning depends on part geometry, production volume, and functional requirements.

From CAD to Part: The Process

Honyo Prototype executes a rigorously controlled CNC machining process for medical device components, adhering strictly to ISO 13485 standards and regulatory requirements. Our workflow integrates advanced digital tools with domain-specific medical manufacturing expertise to ensure compliance, precision, and traceability. Below is the detailed process flow for medical-grade CNC parts:

CAD Upload and Medical Requirements Validation
Clients initiate the process by uploading CAD files (STEP, IGES, or native formats) via our secure customer portal. Our system immediately performs automated validation checks against medical industry constraints, including material biocompatibility requirements (e.g., ASTM F863 for implantables), minimum feature tolerances per ISO 2768-mK, and surface finish criteria (Ra ≤ 0.8 µm for critical surfaces). Non-compliant geometries trigger instant notifications to the client before proceeding.

AI-Powered Quoting with Medical Compliance Layer
Our proprietary AI quoting engine analyzes the validated CAD data while incorporating medical-specific parameters absent in standard quoting systems. The algorithm cross-references material databases for USP Class VI and ISO 10993-5/10 certified options (e.g., Ti-6Al-4V ELI, PEEK, 316LVM stainless steel), factors in cleanroom production surcharges (ISO Class 7 or better), and embeds regulatory documentation costs. Quotes explicitly itemize compliance overheads such as material mill certificates, batch traceability logs, and 2D inspection reports per ASME Y14.5. Typical quote turnaround is under 2 hours for standard medical components.

Medical-Focused DFM Analysis
Unlike generic DFM, our engineering team conducts a dual-path analysis:
First, manufacturability optimization for tight-tolerance medical features (e.g., threaded inserts in polymer housings, micro-bore tolerances ±0.005mm).
Second, regulatory risk assessment covering sterilization compatibility (EtO/gamma resistance), particulate control protocols, and design validation against FDA 21 CFR Part 820.30. We provide annotated CAD markups with actionable recommendations, such as modifying draft angles to prevent molding defects in subsequent assembly stages. This phase includes mandatory client engineering sign-off on DFM outputs.

Precision Production Under Medical Protocols
All medical CNC runs occur in dedicated ISO Class 7 cleanrooms with environmental monitoring (particulate counters, temperature/humidity logs). Key production controls include:
Material verification via PMI (Positive Material Identification) upon receipt
In-process inspections using calibrated CMMs with NIST-traceable reports
Dedicated tooling sets for medical batches to prevent cross-contamination
Real-time SPC (Statistical Process Control) for critical dimensions
Full batch traceability via serialized barcoding from raw material to finished part

Regulatory-Compliant Delivery
Shipments include a comprehensive documentation package beyond standard COAs:
Material test reports with full chemical composition
Sterilization validation summary (if applicable)
Dimensional inspection report against drawing GD&T
ISO 13485:2016 certified conformance statement
Certificate of Free Sale for export shipments
All parts undergo final particulate testing per ISO 14644-1 prior to packaging in ISO 11607-compliant sterile barrier systems. Typical delivery includes 48-hour shipping with real-time logistics tracking and customs documentation pre-validated for medical device shipments.

This end-to-end process ensures medical device manufacturers receive fully documented, audit-ready components that accelerate their regulatory submissions while minimizing rework risks. Honyo maintains a 99.2% first-pass yield rate for Class II/III medical device components through this integrated workflow.
