How does a medical parts processing factory produce medical components through CNC processing

The items processed and manufactured by the medical parts processing factory through CNC include various surgical instruments used in medical surgeries, such as cannula needles (skin piercers), bone drills and saws. When CNC machining is used, parts are usually milled with 3 to 5 axes or turned with a moving tool CNC lathe.

​

The most common types of machines used in the manufacturing process of medical parts include CNC milling machines, lathes, drilling machines and computerized milling machines. Reliability and high quality are the top priorities in the processing of medical components. Therefore, the medical device industry has put forward new requirements for professional precision cutting tools. Difficult-to-machine materials, complex workpiece shapes, and frequent CNC small-batch production have placed very high demands on the cutting tools used for processing professional medical devices. It is mainly manifested in:

The requirements for cnc machining machines are relatively high

Advanced medical device processing equipment such as Swiss automatic lathes, multi-spindle machine tools and rotary tables are completely different from the commonly seen machining centers and lathes. They are very small in size and very compact in structure. To meet such requirements, the structure of the cutting tools also needs to be specially designed. The size of the cutting tools should be very small, and at the same time, the rigidity of the cutting tools should be guaranteed.

2. High efficiency is required for cnc machining

For medical devices, the most valued aspect is processing efficiency, that is, processing rhythm. It is required that the blades can be replaced in the shortest possible time.

3. In terms of the workpiece itself, it is quite different from other mechanical components. Medical devices implanted in the human body are first required to have an extremely smooth surface and very high precision, without any deviation. This demands that the design of the blade structure and the blade coating of the cutting tools all meet very high processing requirements.

4. CNC machining requirements:

Tolerances within the micrometer range are very common in the medical industry. Choosing the right cutting tool requires acute insight and rich experience. On the one hand, even when drilling small holes, lubricants need to be used to reduce friction, reliably dissipate heat and handle fine iron filings at the cutting edge. On the other hand, when manufacturing cutting-edge medical devices (without burrs), sharp and smoothly running cutting tools are needed to achieve high-quality surfaces.
