Technical Capabilities

CNC machining in the medical industry demands high precision, repeatability, and compliance with stringent regulatory standards due to the critical nature of medical devices and components. Multi-axis milling (3, 4, and 5-axis) and precision turning are widely used to produce complex geometries such as surgical instruments, implantable devices, diagnostic equipment parts, and fluid handling components. These processes support tight tolerances typically ranging from ±0.0002″ to ±0.001″ (5–25 µm), often required for biocompatible and sterilizable parts.

The following table outlines key technical specifications for CNC machining in the medical industry, focusing on multi-axis capabilities, turning, tight tolerance performance, and common engineering materials:

Parameter	Specification Details
Machining Processes	3-Axis, 4-Axis, and 5-Axis CNC Milling; CNC Turning (including Swiss-type for small, complex parts)
Tolerance Capability	±0.0002″ (5 µm) to ±0.001″ (25 µm); tighter tolerances achievable with process validation and CMM inspection
Surface Finish (Typical)	16–32 µin Ra (standard); down to 8 µin Ra with polishing or specialized tooling
Positional Accuracy	±0.0001″ (2.5 µm) with calibrated machines and thermal compensation
Repeatability	< ±0.0002″ (5 µm) across production runs with proper fixturing and process control
Materials – Metals	Aluminum (6061, 7075, 2024), Stainless Steel (316L, 17-4 PH), Titanium (Grade 5), Inconel
Materials – Plastics	ABS (USP Class VI compliant grades), Nylon (6, 66, GF-reinforced), PEEK, Polycarbonate
Machining Environment	Cleanroom-compatible setups (ISO Class 7 or better); non-contaminating coolants/lubricants
Certifications & Compliance	ISO 13485, FDA 21 CFR Part 820, RoHS, biocompatibility (ISO 10993) for implantable materials
Inspection & Validation	In-process probing, CMM (Coordinate Measuring Machine), optical comparators, first-article inspection (FAI), PPAP documentation

Advanced 5-axis milling enables single-setup machining of complex organic shapes found in orthopedic implants and cranial plates, reducing human error and improving geometric accuracy. Precision CNC turning is essential for shafts, connectors, and cannulated components used in minimally invasive devices. Material selection is driven by sterilization requirements (e.g., repeated autoclaving), mechanical performance, and regulatory compliance—316L stainless steel and PEEK are common for implantable applications, while aluminum and ABS are used for housings and non-implantable instruments.

All processes are supported by full documentation traceability, including lot tracking, material certifications, and inspection reports, ensuring compliance with medical device quality management systems.

From CAD to Part: The Process

Honyo Prototype Medical CNC Machining Process Overview
Honyo Prototype delivers precision CNC machining for medical devices through a rigorously controlled workflow designed to meet ISO 13485, FDA 21 CFR Part 820, and ASTM F2992-15 standards. Our process ensures biocompatibility, traceability, and zero-defect delivery for implants, surgical instruments, and diagnostic components. Below is the end-to-end sequence:

CAD File Submission
Clients upload native CAD files (STEP, IGES, or Parasolid formats) via our secure portal. Medical submissions require explicit notation of critical features: surface finish tolerances (e.g., Ra 0.8 µm for implant interfaces), material specifications (e.g., ASTM F136 Ti-6Al-4V ELI), and regulatory classifications. Non-conforming files trigger immediate feedback loops to prevent downstream delays.

AI-Powered Quoting System
Our AI engine analyzes geometric complexity, material certifications, and medical-specific requirements to generate instant quotes. Key differentiators include:
Real-time cost modeling for biocompatible alloys (e.g., 316LVM stainless steel, PEEK) with certified mill test reports
Automated identification of sterilization-impacting features (e.g., blind holes requiring electropolishing)
Lead time calculation incorporating mandatory cleanroom scheduling (ISO Class 7) and 100% first-article inspection

Medical-Grade DFM Analysis
Engineers perform mandatory Design for Manufacturability reviews focused on medical compliance. This phase includes:

DFM Parameter	Medical Industry Requirement	Honyo Action
Material Selection	ASTM/ISO biocompatibility certs	Verify mill certs; reject uncertified lots
Surface Finish	Ra ≤ 0.4 µm for implant contact	Recommend honing/electropolish steps
Tolerancing	±0.005 mm critical dimensions	Flag GD&T conflicts with ASME Y14.5
Cleanability	No crevices > 0.1 mm	Suggest radius modifications

Clients receive a formal DFM report with actionable recommendations. 92% of medical projects require 1–2 design iterations before approval.

Precision Production Execution
Machining occurs in dedicated ISO 13485-certified cleanrooms using:
Swiss-type lathes (e.g., Tornos Bechler) for catheter components with ±0.002 mm tolerances
5-axis mills (DMG MORI) with in-process probing for orthopedic implant geometries
Dedicated tooling for medical-grade materials to prevent cross-contamination
All operations follow validated work instructions with real-time SPC monitoring. Every lot includes full material traceability from ingot to finished part.

Regulatory-Compliant Delivery
Shipments include:
Certificate of Conformance with material heat numbers and AS9100/ISO 13485 documentation
First-article inspection reports (FAIR) per AS9102 format with CMM data
Sterilization validation support documentation (e.g., EtO residuals testing protocols)
Parts are packaged in ISO 11607-compliant sterile barrier systems with lot-specific RFID tracking. Final delivery includes digital quality dossiers for seamless FDA/europen regulatory submissions.

This integrated process reduces time-to-market for medical clients by 30% while maintaining zero non-conformances in recent FDA audits. All personnel undergo annual GMP training with device-specific competency validation.
