What's The Project Challenge For The Projects?
The main challenge is the product feature is very complex, we need to machining these surface one by one, and all of parts need be assembled and make function purposed. The materials itself is very hardness, and it is not easy to machining. The single part for special dimensions tolerance is under 0.01mm, ask all of parts can be assembled and functional.
Our engineering team have to use extended cutting tool, and 5 axis and 3+2 axis CNC milling machine to complete them. The parts include multi-angle holes (the 25 holes of the bone plate are distributed in 10 different angles), microchannels (with a width of only 100 μm), and thin-walled structures (with a thickness of 0.55 mm). Also, there are five holes are undercut, and a series of grooves along the tapered these holes are accurate hole under 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, and efficiency needs to be improved through automation.
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 the Cutting Programs When Necessary
The mainstream technology achieves complex surface shaping through 5-axis linkage for the curved surface finishing of the actuating support requires a 3mm tool.
Using the mirror EDM process for minor undercut features, as the CNC milling can't machine these areas.
Surface polishing process to meet the whole product assembly and appearance needs.
Titanium alloy and stainless steel parts require sonicleaning after machining.
How To Develop and Manufacturing CNC Machining Medical Device Parts
Most of the medical device parts' CNC machined machining included rapid prototype and volume production. When we make the 2–4 prototypes, we have to consider using 5-axis CNC machines and turn-mill combination to manufacture them, then have after machining finishing process.
So the whole manufacturing cost is very higher.
Medical device parts need us to further consider the whole process from single part machining, surface coating, and assembly — this is one very complex process.
When you have these medical device parts CNC machined inquire or customized parts, you can send out inquire to our email address so our engineer team will discuss with you on each of production details. Whatever you will ask 1 pc or more 100 pcs, we will make the best support to you based on cost-effective. Tell us your requirement or expectation, 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?
After most of the medical device parts are CNC machined, we will provide good finishing options:
- Polishing
- Anodizing
- Powder Coating
- Silk-Screen
- Sonicleaning
Actuating Device parts, after CNC milling, turning and EDM process, we will have polishing and sonicleaning process to make it to aesthetic.
