A detailed explanation of the basic properties of SUS materials, advanced deep hole machining techniques, and their countermeasures!
In the medical field, materials such as SUS (stainless steel) are essential to meet the high demands for safety and precision in medical devices, surgical instruments, and implants. While it excels in corrosion resistance and biocompatibility, its low thermal conductivity and work hardening characteristics require advanced technology and process management for deep hole machining. Here, we will provide a detailed explanation of the technical challenges and countermeasures in deep hole machining of SUS materials, as well as specific application examples in the medical field. *For more detailed information, please refer to the related links.
