Precision tooling for the medical component industry


Continuing advances from Sandvik Coromant

Our solutions for machining a wide range of implants, such as bone screws and hip joints, are a direct route to achieving the many complex components now at the leading edge of medical science.

Highly corrosion and wear resistant titanium, stainless steels and special alloys are needed to withstand the demands of the human body but can place extreme challenges on effective machining.

We have developed advanced tooling and strategies for these applications, designed to meet the essential quality standards of this industry. 




Clinical precision

Cutting edge tooling from the leading innovators in the medical implant industry – tolerances within microns, at the lowest possible cost per component.

  • Razor sharp inserts for the highest precision components.
  • High tolerance turning, grooving and threading for mass production
  • Secure and stable parting and grooving.
  • Solid carbide drills for effi cient small hole making.

    A medical breakthrough   


    The spherical turning of hip joints with round inserts was our fi rst concept designed for advances in the medical industry. Now available for diameters down to 20 mm, they offer a wider application, allowing you to double productivity and reduce tooling costs by a third. Sandvik Coromant can open the door to innovations for medical excellence, now and into the future.
