Why is CNC machining required for medical devices?

Medical devices typically impose stringent demands on dimensional accuracy and surface quality. Take artificial joints as an example; they must match human bones with extreme precision, and their dimensional accuracy requirements often reach the micron scale. Through meticulous programming and precise control, CNC machining can carry out high - precision operations like cutting, milling, and drilling. This ensures that the dimensional accuracy and surface roughness of medical devices fully meet the stipulated requirements, thus ensuring their excellent compatibility with human tissues and proper functionality.
