Medical device components demand a level of precision, cleanliness, and documentation that goes beyond standard industrial machining. Whether you're machining a surgical instrument from 316L stainless, a spinal implant from Ti-6Al-4V ELI, or a diagnostic device housing from PEEK, every aspect of the manufacturing process — from raw material traceability to final surface finish — needs to be controlled and documented.
Rapid Manufacturing's supplier network includes manufacturers with experience in medical device production. We match your project requirements — material, tolerance, finish, documentation level — to the right supplier and manage the process from quote to delivery.
Key capabilities available through our network: 5-axis CNC milling for complex implant geometries, CNC turning for screws, pins, and shafts, wire EDM for precision cutting profiles in titanium and stainless, surface grinding for ultra-flat sealing faces, electropolishing for 316L stainless instruments, and CMM inspection with full dimensional reporting.
Biocompatible Materials
Titanium Grade 2 (Pure)
Dental implants, bone plates, non-load-bearing implants
Maximum biocompatibility — the standard for osseointegration applications
Titanium Ti-6Al-4V ELI (Grade 23)
Orthopaedic implants, spinal cages, trauma fixation
ELI grade has improved fatigue life vs standard Grade 5 — required for long-term implants
316L Stainless Steel
Surgical instruments, retractors, trays, non-implantables
Low carbon grade — resists sensitisation during sterilisation cycles
PEEK
Spinal implants, trauma implants, radiolucent components
Invisible on X-ray, bone-like elastic modulus, excellent biocompatibility
Cobalt-Chrome (Co-Cr-Mo)
Hip/knee implant components, wear-resistant surfaces
Exceptional wear resistance — used in articulating joint replacement surfaces
Delrin / Acetal
Instrument handles, non-implantable device components
Chemically resistant, EtO sterilisable, low friction
Medical CNC Machining FAQ
What materials are used for CNC machined medical device components?
The most common biocompatible materials for CNC machined medical components are: titanium Grade 2 (commercially pure, for implants and bone screws), titanium Ti-6Al-4V ELI Grade 23 (for load-bearing implants — extra low interstitials for improved fatigue life), 316L stainless steel (for surgical instruments, retractors, trays, and non-implantable devices), PEEK (polyether ether ketone — for spinal implants and components requiring radiolucency), Delrin/Acetal (for non-implantable instrument handles and components), and cobalt-chrome alloys (for orthopaedic implants). Material selection depends on biocompatibility requirements, sterilisation method, and whether the device is implantable.
What surface finish standards are required for medical CNC machining?
Surface finish requirements for medical components vary significantly. Surgical instruments typically require Ra 0.8μm or better on contact surfaces. Implantable components may require Ra 0.4μm or mirror-polished surfaces (Ra 0.1μm) for osseointegration or articulating surfaces. All sharp edges must be radiused or deburred. Electropolishing of 316L stainless steel is common for surgical instruments — it removes surface contamination, improves corrosion resistance, and makes cleaning easier. Specify your surface finish requirement in Ra value or describe the intended use and our team will advise.
Do your suppliers hold ISO 13485 certification?
Rapid Manufacturing works with ISO 13485-aware suppliers in our network. For projects with formal ISO 13485 requirements, we match you with appropriately certified suppliers. Include your quality system requirements in your quote request and we will confirm which suppliers in our network meet your needs and provide documentation accordingly.
What documentation do medical device machining projects require?
Medical CNC machining projects typically require: material certifications with lot traceability, Certificate of Conformance (CoC), dimensional inspection reports (CMM for critical features), surface finish measurements, and for implantable devices — biocompatibility documentation per ISO 10993. Some projects require full Device History Records (DHR). Specify your documentation requirements upfront so we can match you with suppliers who maintain appropriate records.
Can you machine PEEK for medical applications?
Yes. PEEK (polyether ether ketone) is increasingly used in spinal surgery, trauma fixation, and dental implants due to its radiolucency (invisible on X-ray), excellent biocompatibility, and mechanical properties similar to cortical bone. CNC machining of PEEK requires dedicated machines or thorough cleaning protocols to avoid cross-contamination with other materials. Our suppliers who work with PEEK for medical applications maintain appropriate segregation protocols.
What sterilisation methods are compatible with machined medical components?
This depends on the material. 316L stainless steel and titanium are compatible with autoclaving (steam sterilisation), EtO (ethylene oxide), and gamma radiation. PEEK is autoclave-compatible but may discolour slightly. Delrin/Acetal can be EtO sterilised but not autoclaved at high temperatures. When specifying your medical machining project, include the intended sterilisation method so the correct material and surface treatment can be selected.
How do I get a quote for medical device CNC machining?
Upload your CAD file (STEP preferred) and 2D drawing at rapidmanufacturing.com.au/quote. Include material specification with grade, surface finish requirements in Ra value, GD&T callouts from your drawing, required quantity, any special processes (electropolishing, passivation, anodising), documentation requirements, and intended use (implantable, non-implantable, instrument). Our team reviews all medical quote requests manually.
