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.

This product is a high-precision medical catheter tip that is compatible with difficult-to-machine materials such as SUS316 and SUS304. It achieves a machining precision of ±0.01mm within an outer diameter range of φ1 to 5mm and can accommodate a surface roughness of Ra0.8. The fine processing of the tip shape ensures both insertability and safety within body cavities and blood vessels. Our in-house integrated system enables short delivery times and high quality, with a proven track record and reliability in the medical device field. 【Features】 ■ High-precision machining of small-diameter precision parts from φ1 to φ5 using NC automatic lathes ■ Stable maintenance of dimensional accuracy of ±0.01mm even with difficult-to-machine materials like SUS316 and SUS304 ■ Surface roughness and dimensional measurement system using image measuring instruments ■ Consistent support from prototype to mass production, achieving short delivery times and stable quality ■ ISO9001 certification obtained, establishing a quality assurance system from order to delivery ■ In-house integrated support available for surface treatment, cleaning, and inspection *For more details, please feel free to contact us.
