Production Capability For Medical Devices Products CNC Machined Manufacturer
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 serve their functional purpose. 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 fully 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, with a series of grooves along the tapered holes requiring precise concentricity and tolerance control.
Thin-walled parts are prone to deformation due to cutting force or clamping force. 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%.
Full lifecycle data recording is required, including material batches, processing parameters, and test reports, 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.
Fabricating The Prototypes
The first run of prototypes was CNC machined from aluminum in a 5-step process:
- CNC Program the Machines
- Engineering Review and Improve the Codes
- Mount the Workpiece on the Machine and Adjust the Setup
- Monitor Production and All Functions
- Do Adjustment to the Cutting Programs When Necessary
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.
- Mirror EDM Process: Used for minor undercut features that CNC milling cannot reach.
- Polishing Process: Surface polishing is performed to meet the whole product assembly and appearance requirements.
- Surface Finishing After Machining: Titanium alloy and stainless steel parts require sonicleaning.
How To Develop and Manufacturing CNC Machining Medical Device Parts
Most 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 whole manufacturing cost is therefore very high. Medical device parts require us to further consider the entire process — from single part machining, surface coating, and assembly — making it a very complex workflow.
We are dedicated to rapid prototyping and low-volume production for medical device parts, providing fast feedback and delivery with high quality. We can manufacture whole-industry medical device parts — customized to your needs — whether you need 1 pc or more than 100 pcs, we can meet your requirements.
When you have medical device parts CNC machining inquiries or customized part needs, send your inquiry to our team. Our engineers will discuss every production detail with you. Whatever you need — 1 pc or 100+ pcs — we will make the best cost-effective support for you. Tell us your requirement or expectation, and our team will make it happen. You can start a new project now.
What's The Surface Finishing Can Be Done After CNC Machining?
After most medical device parts are CNC machined, we provide excellent finishing options to meet aesthetic and functional requirements.
For Actuating Device parts, after CNC milling, turning, and EDM processes, we perform polishing and sonicleaning to achieve an aesthetic and clean finish.
