    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 for special dimensions tolerance is under 0.01mm, requiring all parts to be assembled and fully functional.

    Our engineering team have to use extended cutting tools, and 5-axis and 3+2 axis CNC milling machines to complete them. The parts include multi-angle holes (25 holes of the bone plate 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 undercut holes, and a series of grooves along the tapered holes requiring accurate concentricity and tolerance control.

    Deformation 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%.

    Quality Traceability System

    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.

    Cost and Efficiency Balance

    Customers often demand competitive prices including material and machining process. Creatingtec offers these suggestions to customers for review. For example, 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.

    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:

    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 of the Cutting Programs When Necessary

    High Precision CNC Milling & Turning

    5-axis linkage for complex surface shaping; curved surface finishing of actuating support requires a 3mm tool.

    Mirror EDM Process

    Used for minor undercut features that CNC milling cannot reach.

    Polishing Process

    Surface polishing to meet whole product assembly and appearance requirements.

    How To Develop and Manufacturing CNC Machining Medical Device Parts

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

    So the whole manufacturing cost is very high. Medical device parts require us to further consider the whole process from single part machining, surface coating, and assembly — this is a very complex process.

    We are dedicated to rapid prototype and low volume production for medical device parts and provide fast feedback and delivery to you with high quality. We want to make whole industry medical device parts CNC machined for you, provide you customized parts whatever 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, you can send your inquiry to our team and our engineers will discuss with you on each production detail. Whatever you ask — 1 pc or more than 100 pcs — we will make the best support to you based on cost-effectiveness. 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 including:

    ✔ 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 aesthetic.

    Frequently Asked Questions
    What materials are used for CNC machining medical actuating device parts?
    We primarily use Titanium alloy, PEEK, and 316L stainless steel for medical actuating device parts. These materials are chosen for their biocompatibility, corrosion resistance, and mechanical strength required in medical applications.
    What tolerances can you achieve for medical device CNC machining?
    Our CNC machining capabilities can achieve tolerances as tight as 0.005mm on grinding machines and 0.01mm for special dimensional tolerances on individual parts. We use 5-axis CNC machining centers and slow-EDM to ensure all parts can be assembled and function correctly.
    What surface finishing options are available after CNC machining of medical parts?
    After CNC machining, we offer a range of surface finishing options including polishing, anodizing, powder coating, silk-screen printing, chemical nickel-plating, and sonicleaning. For titanium alloy and stainless steel medical parts, sonicleaning is a standard requirement to ensure cleanliness and surface quality.
    Do you support both prototype and volume production for medical device parts?
    Yes. We are dedicated to rapid prototyping and low-to-high volume production for medical device parts. We can fulfill orders from as few as 1 piece to over 100 pieces with no minimum volume requirements, providing fast feedback, high quality, and competitive pricing throughout.
    How do you ensure quality control and traceability for medical device parts?
    We implement a full lifecycle quality traceability system that records material batches, processing parameters, and test reports to meet medical standards such as ISO 13485. We also apply Positive Material Identification (PMI) to verify the composition of alloys used in tools and parts.
    How do you handle complex features such as thin walls, microchannels, and multi-angle holes in medical parts?
    Our engineering team uses extended cutting tools, 5-axis and 3+2 axis CNC milling machines, and mirror EDM processes to handle complex features. For thin-walled structures (as thin as 0.55mm), we apply flexible vise clamping and staged processing (coarse/semi-finish/finish machining) to control deformation and maintain dimensional accuracy.
