Semi-circular slope milling finishing of internal surfaces is an efficient and safe finish, based on the advantages of longer tool life, lower chance of tool breakage and shorter finishing times to obtain a high quality surface. We recommend the use of round inserts with a positive front angle.

The advantages when finishing outer spheres include longer tool life and safe and reliable machining processes.

External femoral finishing maintains a high quality surface and a longer tool life according to a safe and reliable machining process. The safe use of positive front corner round inserts is recommended.
