China CNC Machining Suppliers for Medical Device Parts | Quality Factory for Surgical Instruments and Actuating Devices
Project Description
⚙ Production Capability For Medical Devices — CNC Machined Manufacturer
5 sets of 5-axis CNC machining centers and 8 sets of 3+2 axis CNC milling machines.
2 sets slow-EDM, 2 sets larger Lathe, and 2 sets grinding machines under 0.005mm tight tolerance.
Secondary finishing including anodizing, powder coating, chemical nickel-plating and more.
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 dimension 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 across 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 in stages) are required. For example, in the processing of aluminum alloy medical accessories, process optimization reduces 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 (e.g., total processing time for bone plates reaching 1 hour and 11 minutes), and efficiency is improved through automation such as the double workstation system.
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
Mainstream technology achieving complex surface shaping through 5-axis linkage. Curved surface finishing of the actuating support requires a 3mm tool.
Using the mirror EDM process for minor undercut features that CNC milling cannot reach.
Surface polishing process to meet the whole product assembly and appearance requirements.
Titanium alloy and stainless steel parts undergo sonicleaning after all machining is complete.
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.
Medical device parts require us to further consider the whole process — from single part machining, surface coating, to assembly. This is one very complex process, and the overall manufacturing cost is correspondingly higher.
We are dedicated to rapid prototype and low-volume production for medical device parts, providing fast feedback and delivery with high quality. We manufacture whole-industry medical device parts via CNC machining — customized parts whether you need 1 pc or more than 100 pcs, we can meet your requirement.
When you have medical device parts CNC machining inquiries or customized parts needs, send your inquiry to our engineering team and we will discuss each production detail with you. Whatever you ask — 1 pc or more than 100 pcs — we will provide the best cost-effective support. Tell us your requirement or expectation, and our team will make it for you. You can start a new project now.
What's The Surface Finishing Can Be Done After CNC Machining?
Polishing — Achieves smooth, reflective surfaces for aesthetic and functional requirements.
Anodizing & Powder Coating — Provides corrosion resistance and color options for medical parts.
Silk-Screen & More — Additional finishing options available based on product requirements.
Sonicleaning — Applied to Actuating Device parts after CNC milling, turning, and EDM to achieve a clean, aesthetic finish.
