How does CNC machining make medical parts?

Items manufactured by CNC machining include various surgical instruments used in medical procedures, such as trocars (skin piercers), bone drills, and saws. When machining with CNC, parts are usually milled with 3 to 5 axes or turned with a live tool CNC lathe. The most common types of machines used in the manufacturing of medical parts include CNC milling, lathing, drilling, and computerized milling. Reliability and high quality are the top priorities in the processing of medical parts, so the medical device industry has put forward new requirements for professional precision tools. Difficult-to-machine materials, complex workpiece shapes, and frequent CNC small-batch production are very important for machining professional medical tools. The knives of the instruments make high demands. Mainly in:

1. The requirements for CNC machine tools are relatively high

Advanced medical equipment processing equipment such as Swiss automatic lathes, multi-spindle machine tools, and rotary tables are completely different from the usual machining centers and lathes. Their size is very small and the structure is very compact; to meet such requirements, the structure of the tool is also A special design is required, the size of the tool is required to be small, and the rigidity of the tool is also guaranteed.

2. High requirements for CNC processing efficiency

For medical devices, the most important thing is processing efficiency, that is, the processing cycle, which requires the blade to be replaced in the shortest time.

3. From the perspective of the workpiece itself, it is very different from other mechanical parts; the medical device implanted in the human body requires first of all a very good finish, very high precision, and no deviation, which requires the cutting tool from the blade structure. From the design to the design of the insert coating, the high machining requirements are met.

4. CNC machining requirements:

Tolerances in the micron range are common in the medical industry, and choosing the right tool requires keen insight and extensive experience. On the one hand, even drilling small holes requires the use of lubricants to reduce friction, reliably dissipate heat and handle fine iron filings at the cutting edge; cutting tools for high-quality surfaces.
