We hold tight tolerances on complex geometries. Ball-and-socket interfaces, tapered stems, and threaded locking mechanisms are routine. Our 5-axis machines reduce setups. Fewer setups mean better concentricity and repeatability.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality.
Every batch gets a unique lot number. Raw material certificates are stored. Heat numbers are recorded. If a question arises, we trace the part back to the exact bar of metal. No guesswork.
2. Inspection report per batch.
You receive a full dimensional report with every shipment. CMM data points, surface roughness readings, and thread gauges results. We do not ask you to trust us. We show you the numbers.
3. One factory for CNC + stamping + springs + heat sinks.
Prosthetic assemblies often need more than machined parts. We make springs for locking mechanisms. We stamp brackets for external fixators. We machine heat sinks for motorized prosthetics. One purchase order. One quality system. One shipping date.
Where These Parts Are Used
CNC machined prosthetic joint components appear in load-bearing and articulating applications.
Knee replacements: Femoral components and tibial trays. We machine the curved condylar surfaces to Ra 0.2 µm. The mating surface must slide smoothly for 10+ years.
Hip implants: Femoral stems and acetabular shells. Taper locks require ±0.005 mm on the Morse taper. Our Swiss lathes hold this consistently.
Ankle and shoulder joints: Small, complex geometries. We use 5-axis milling for the multi-radius articulating surfaces.
External prosthetic frames: Custom CNC machining for lightweight aluminum or titanium pylon connectors. Threaded holes and quick-release mechanisms.
Test fixtures and surgical guides: Prototype runs for R&D labs. We machine one-off parts for cadaver testing and clinical trials.
These parts face cyclic loading, body fluids, and strict regulatory scrutiny. Our machining processes are validated. Our inspection methods are repeatable.
Questions Buyers Ask Before Ordering
Q: Do you really have no MOQ?
A: Yes. We machine one prototype for your validation. We machine 50,000 pieces for production. The setup cost is the same. The per-piece price drops with volume. No minimum order to start.
Q: How do you guarantee tolerance and quality?
A: We use in-process probing on the machine. After machining, we verify with a CMM. The inspection report is included with your shipment. If a dimension is out of spec, we rework or replace at no cost.
Q: What is the typical lead time?
A: Prototypes ship in 5–7 days. Production runs of 1,000 pieces ship in 10–15 days. Urgent orders can be expedited to 72 hours for simple geometries. We confirm exact dates after reviewing your drawing.
Q: Can you provide material certificates?
A: Yes. Every batch includes mill certificates for the raw material. We also provide heat treatment reports if required. For medical devices, we supply full traceability documentation.
