China Medical Device Parts CNC Machining Factory - Quality Suppliers for Surgical Instrument Actuating Devices
Project Description
What's The Project Challenge For The Projects?
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 and made functional. The materials themselves are very hard and not easy to machine. The single part special dimensional tolerance is under 0.01mm, requiring all parts to be assembled and functional.
Our engineering team uses 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.
Thin-walled parts are prone to deformation due to cutting force or clamping force. Therefore, flexible vise clamping and staged processing (coarse/semi-finish/finish machining carried out in stages) are required. For example, in the processing of aluminum alloy medical accessories, process optimization is needed to reduce the deformation rate from 5% to below 0.3%.
It is necessary to achieve full lifecycle data recording, including material batches, processing parameters, test reports, etc., to meet medical standards such as ISO 13485.
Customers often demand competitive prices including material and machining process. Creatingtec offers these suggestions to customers for review. High-precision processing takes a long time (such as the total processing time for bone plates reaching 1 hour and 11 minutes), and efficiency needs to be improved through automation such as double workstation systems.
How To Understand and Make The Parts?
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.
The first run of prototypes was CNC machined from aluminum in a 5-step process:
CNC milling process: the mainstream technology achieves complex surface shaping through 5-axis linkage for the curved surface finishing of the actuating support, which requires a 3mm tool.
Using the mirror EDM process for minor undercut features, as CNC milling cannot machine these areas.
Surface polishing process is performed to meet the whole product assembly and appearance needs.
Titanium alloy and stainless steel parts require sonicleaning after all machining processes are complete.
How To Develop and Manufacturing CNC Machining Medical Device Parts
Most medical device parts CNC machining includes rapid prototyping and volume production. When making 2–4 prototypes, we consider using 5-axis CNC machines and turn-mill combinations to manufacture them, followed by after-machining finishing processes.
Medical device parts require careful consideration of the whole process — from single part machining, surface coating, to assembly — making this a very complex process.

What's The Surface Finishing Can Be Done After CNC Machining?
After most medical device parts are CNC machined, we provide high-quality finishing options:
For Actuating Device parts, after CNC milling, turning and EDM processes, we perform polishing and sonicleaning to achieve the required aesthetic and functional standards.
