VMT’s CNC Machining Medical Part Success Story

VMT Achieving Sub-200µm Micro-Channels with Ultra-Smooth <0.2µm Ra Surface Finish for CNC Machining Medical Devices

Client Overview

Leading Medical Instrument Manufacturer

A leading medical technology firm required an implantable diagnostic device with intricate micro-fluidic pathways. Their design demanded sub-200µm micro-channels with an ultra-smooth surface finish of less than 0.2µmRa, specifications that had proven unattainable with their previous manufacturing partners.

These dimensions weren’t arbitrary; they were critical for both the device’s functionality, ensuring proper fluid dynamics at micro-scales and biocompatibility, as surface roughness can trigger adverse tissue reactions when implanted long-term.

CNC Persicion Machining Medical Devices with Ultra-Smooth Surfaces

The Challenge

CNC Micro-Machining Medical Parts Fell Short

The medical company faced significant technical and challenges with their implantable diagnostic device components. They had already attempted production with one manufacturer, encountering consistent failures.

Inadequate Channel Precision

Previous attempts resulted in inconsistent channel dimensions, with variations exceeding 30µm, well beyond the ±5µm requirement. This caused unpredictable fluid flow patterns in testing.

Surface Finish Failures

Surface finishes measured 0.8-1.2µmRa, 4-6 times the required specification. Internal channel surfaces were even worse due to tool access limitations, measuring 1.5µmRa or higher.

Excessive Lead Times

Each prototype iteration required 4-6 weeks, with no guarantee of success. This glacial pace threatened to delay clinical trials and product launch by months.

Tooling Limitations

Previous manufacturers lacked specialized micro-tools and fixturing required for such precise micro-machining, resulting in excessive vibration, tool deflection, and poor surface integrity.

Their CNC machining implantable diagnostic device parts required micro-channels smaller than 200 microns with an ultra-smooth surface finish of less than 0.2 micrometers Ra. These specifications weren’t just arbitrary, they were critical for both the fluid dynamics performance and long-term biocompatibility of the device once implanted.

VMT Advanced Finishing for Ultra-Smooth Surfaces

Achieving CNC machining medical devices with <0.2µmRa surface finishes required specialized post-machining processes tailored for micro-scale features.

Micro-Electropolishing
A proprietary electrochemical process that removes surface material at the micro-level, reducing roughness to <0.2µmRa even within complex sub-200µm channels.

Controlled Passivation
A precisely controlled chemical treatment that enhances corrosion resistance while maintaining the ultra-smooth surface finish required for biocompatibility.

Advanced Metrology
Confocal microscopy and white light interferometry to verify surface finish across all areas, including internal micro-channels.

These specialized processes are where VMT truly distinguishes itself. While other manufacturers can achieve either small channels or smooth surfaces, our expertise lies in delivering both simultaneously, creating sub-200µm micro-channels with <0.2µmRa surface finishes that meet the stringent requirements of implantable medical devices.
