Production Capability For Medical Devices Products CNC Machined Manufacturer

The main challenge is the product feature is very complex — we need to machine these surfaces one by one, and all parts need to be assembled to serve functional purposes. The materials themselves are very hard and not easy to machine. The single part for special dimensions tolerance is under 0.01mm, requiring all parts to be assembled and fully functional.

Our engineering team must use extended cutting tools, 5-axis and 3+2 axis CNC milling machines to complete them. The parts include multi-angle holes (25 holes distributed in 10 different angles), microchannels (width of only 100 μm), and thin-walled structures (thickness of 0.55 mm). Five holes are undercut, and a series of grooves along the tapered holes require accurate concentricity and tolerance control.

First, we conducted a careful design overview to understand the parts and suggest improvements when possible. Then, we applied Positive Material Identification (PMI) to test the composition of the alloys used in the tools and parts.

Fabricating The Prototypes

The first run of prototypes was CNC machined from aluminum in a 5-step process:

1. CNC Program the Machines
2. Engineering Review and Improve the Codes
3. Mount the Workpiece on the Machine and Adjust the Setup
4. Monitor Production and All Functions
5. Do Adjustment to the Cutting Programs When Necessary

CNC milling process: the mainstream technology achieves complex surface shaping through 5-axis linkage. The curved surface finishing of the actuating support requires a 3mm tool.

Using the mirror EDM process for minor undercut features, as CNC milling cannot access these areas.

Surface polishing is performed to meet the whole product assembly and appearance requirements.

Titanium alloy and stainless steel parts require sonicleaning after machining.

Most of the medical device parts' CNC machining includes rapid prototype and volume production. When making 2–4 prototypes, we consider using 5-axis CNC machines and turn-mill combination to manufacture them, followed by after-machining finishing processes.

The overall manufacturing cost is therefore very high. Medical device parts require us to further consider the whole process — from single part machining and surface coating to final assembly — making it a very complex process.

After most of the medical device parts are CNC machined, we provide quality finishing options:

For Actuating Device parts, after CNC milling, turning and EDM processes, we carry out polishing and sonicleaning to achieve the required aesthetic and functional standards.

We ship parts to our customers for assembling and testing, following each detail for parts function and testing requirements. We collect timely comments for new parts improvement, making each next production run more perfect and smooth. We aim to help our customers achieve the best effective products — good quality, controlled cost, and on-time delivery.
