Machining of bone screws: Precision for safe fixation systems
The highest demands on material, processing and surface quality — for long-lasting and resilient bone screws.
Bone screws are essential fixation aids in modern medical technology and are used in reconstructive and traumatic surgery. They are usually made of titanium (Ti6Al4V ELI) or stainless steel (316LVM) and must have exact dimensional stability and optimum surface quality. Production is often carried out in series production with quantities between 30 and over 1000 units.
One particular challenge is the production of threads via whirling, which is crucial for secure anchoring.

Precise machining for long-lasting bone screws
Specialised manufacturing techniques provide the perfect geometry and surface finish required for safe integration into the body.
Bone screws consist of:
a. Tulip head: Allows connection to rods or plates and provides stable fixation in spinal surgery. Precision engineered for safe and resilient implantation.
b. Screw thread: Optimised thread geometry for maximum bone hold. Specially developed materials and coatings improve biocompatibility and reduce friction when screwing in.
