These parts typically have the following characteristics:
- Strict tolerance requirements (commonly ±0.01 mm or higher)
- High surface quality requirements
- The materials are mostly medical-grade stainless steel or titanium alloy.
- Must comply with quality system standards
For example, compliance with the ISO 13485 quality system has become a crucial threshold for the medical component supply chain. Additionally, products targeting the North American market must also adhere to relevant US Food and Drug Administration regulations.
Compared to other industries, CNC machining for medical devices places greater emphasis on the following capabilities:
1. Precision machining control capability
Thin-walled structures, small-sized holes, and complex contours place high demands on process stability.
2. Material processing experience
Titanium alloys and medical-grade stainless steel are difficult to machine, requiring strict control of cutting tools and parameters.
3. Small batch, rapid delivery
Medical product development cycles are typically short, and prototype verification is frequently required.
In medical projects, manufacturers are not only the implementers of manufacturing, but also need to provide technical advice during the **DFM (Manufacturability Analysis)** phase to reduce design risks and improve manufacturing success rates.
We have extensive experience in machining structural components and precision metal parts for medical devices, enabling rapid delivery from prototype to small-batch production. If you have medical project needs, you can obtain machining suggestions and quotations based on your drawings.
