Medical CNC Project: How We Solved a Challenge for a U.S. Client

This case comes from a U.S. medical device customer. They needed a custom CNC-machined inner shaft used in spinal surgery implants. The part plays a key role in stabilizing the spine during surgery, so precision and quality were critical.

Project Highlights:

• Material: Medical-grade custom stainless steel 416

• Process: Full CNC machining, no casting involved

• Structure: 7 components assembled into one inner shaft

• Requirements: High hardness, medical surface coatings (DLC, TiN), and full documentation (COC, material & inspection reports)

At first, there was a mismatch issue — we didn’t receive the mating nut specifications, which led to a threading problem and rework. The customer also requested surface treatment changes.

How We Handled It:

• Held online meetings to clarify the design

• Re-machined and re-assembled all parts

• Delivered the second batch successfully

• Received positive feedback and were invited for more project quotations

What This Case Shows:

• We understand medical industry standards

• We take full responsibility when problems occur

• We prioritize communication, fast action, and quality assurance
