Features and difficulties of ultra-precision machining of medical device parts

In the new wave of world economic integration, it is a general trend that the global manufacturing industry is accelerating the transfer to mainland China, and China will gradually develop into a world-class manufacturing base.

"Global general machinery, automobiles, aerospace, energy, medical, rail transportation, mold machine tools and other industries are inseparable from tool equipment." From the perspective of future development trends, the global tool market is expected to grow by 3% to 5% annually in the next 5 years. At this rate of growth, we still rank first in the world. From the perspective of domestic tool supply, domestically-made tools occupy the mainstream position, reaching 65%.
The medical device industry is showing a dynamic growth trend. Medical device manufacturers are also continuing to look for better turning centers and tools to enhance their competitive advantages. This has also become an important channel for the growth of the tool industry.

1. The medical device industry puts forward new requirements for professional precision tools

Difficult materials, complex workpiece shapes, and frequent small batch production place high demands on the tools used to process professional medical devices. Such as transplantation products and artificial limbs, play a very important role in successful surgical operations, and can help surgeons achieve the best medical results. The knives used to process medical devices largely determine the quality of medical devices.

Knives have a wide range of uses in the manufacture of medical devices. They can process relatively simple workpieces such as the shell of large equipment (such as computerized tomography cameras), and for the production of transplanted products or workpieces for repairing skull bones or treating fractures. More challenging.

Precision is the most basic requirement in processing

Tolerances in the micrometer range are common in the medical industry, and choosing the right tool requires keen insight and rich experience. On the one hand, even when drilling small holes, you need to use lubricants to reduce friction, reliably dissipate heat and handle fine iron filings at the blade; on the other hand, when producing cutting-edge medical devices (without burrs), you need to use sharpness and smooth operation. Cutting tools to obtain a high-quality surface.
