Items manufactured by CNC include a variety of surgical instruments used in medical procedures, such as trocars (piercers), bone drills and saws. When CNC machining is used, parts are typically milled using 3 to 5 axes or turned using a moveable tool CNC lathe. The most common types of machines used in the manufacturing of medical parts include CNC milling, lathes, drill presses, and computerized milling machines. Reliability and high quality is the top priority of medical parts processing, so the medical device industry has put forward new requirements for professional precision tools difficult-to-process materials, complex workpiece shapes and frequent CNC small batch production of tools for processing professional medical devices put forward high requirements. It is mainly manifested in:
1, the requirements for cnc machining machine tools 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 usual processing centers and lathes, and their size is very small and their structure is very compact; To meet such requirements, the structure of the tool also needs to have a special design, requiring the size of the tool to be small, but also to ensure the rigidity of the tool.
2, high requirements for cnc processing efficiency
For medical devices, the most important thing is the processing efficiency, that is, the processing beat, which requires that the blade can be replaced in the shortest time.
3, from the workpiece itself, and other mechanical parts have a great difference; The medical device implanted in the human body first requires a very good finish, very high precision, and no deviation, which requires the tool from the design of the blade structure to the design of the blade coating to meet high processing requirements.
4, CNC processing 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 dispose of fine iron filings at the blade; On the other hand, when producing cutting-edge medical devices (without burrs), sharp and smoothly running cutting tools are needed to obtain high-quality surfaces.
