We would like to introduce a case study that achieves both high-precision processing and quality stabilization of SUS316 catheter tips. The SUS316 tips used as the tip components of medical catheters faced challenges with variations in dimensional accuracy and surface roughness. By combining high-precision cutting technology using NC automatic lathes with a measurement system utilizing image measurement devices, we have realized stable processing of SUS316. The variations in dimensional accuracy and surface roughness have been significantly improved. 【Case Overview】 ■Challenges - During the mass production process, we were unable to ensure processing stability of the difficult-to-cut material SUS316, leading to issues with quality variations and an increase in the rejection rate during inspection processes. ■Results and Effects - Mass production of the difficult-to-cut material SUS316 has become possible, leading to successful product commercialization. - The rejection rate during inspection processes has decreased, achieving quality stabilization. - This has resulted in increased reliability from medical device manufacturers and continued orders. *For more details, please download the PDF or feel free to contact us.
