Hip Stem Components & Solutions


Hip replacement is currently one of the most common orthopaedic operations and is generally conducted to relieve arthritis pain and overcome hip fractures. Hip replacement generally consists of three parts: the acetabular cup, the femoral component and the articular interface. Femoral hip stems are manufactured from a variety of difficult-to-machine materials such as titanium and cobalt chrome and can be single piece or modular.


Through a combination of patented geometries, high-quality substrates, and coatings, SGS has developed market-leading tools that return tool life measured in hours as opposed to minutes when machining materials such as titanium and cobalt chrome.

Milling of titanium and cobalt chrome
SGS have a range of 3, 4, 5, 6 and 7-flute tooling solutions suitable for slotting, profiling and dynamic milling of difficult-to-machine materials such as titanium and cobalt chrome.
Each tool in the SGS high-performance tool range has specific design features such as variable pitch, helix and rake angle, all aimed at reducing resonance, vibration and chatter, the main causes of premature tool failure.

Z5 HPR milling solutionSGS’s Z5

HPR tool solution is ideal for achieving high material removal rates (MRR) and a finish of 1.8Ra or better in most materials. The specialised 5-flute design is engineered for increased productivity over 3 and 4-flute end mills, whilst its variable geometry design allows for improved chatter suppression for improved tool life. Tool life and productivity is further enhanced via a through coolant option and coatings ideally suited for machining titanium.
