The modern orthopaedic surgery performs miracles which would not have been imaginable a few years ago.


The availability of endoprotheses with a MICROFINISH or Superfinish (improved geometric form and surface quality) has a large share in these miracles. This is more true for the technical optimization of hip joints and cups. The fine machining of these workpieces increases their life by improving the micro and macro geometry, ensuring a high bearing ratio and reducing specifical surface loads. The friction coefficient of the workpieces (depending on the system ball and cup) is being reduced drastically by this method. The abrasion occurring over the years, especially with metal endoprotheses, is reduced to a minimum.

Additionally, this method eliminates the amorphous layers generated by production and previous machining steps, thus the sound basic material with its full hardness and load impact is exposed. A further advantage seen in practice is the increase of the residual stress within the border zone of the material. The machining of BOTH the ball and the cup are possible in our machine.

The resulting workpieces are of the highest quality meeting the highest demands produced within the shortest machining time.
