Secret Answer:     a Satellite Roller Screw!

Application:  a Machine-Tool.



For decades, machine tools received their muscle from acme thread screw, then hydraulic cylinders with the birth of
NC machines, then ball screws with the more recent CNC machinery. 

Then came the need for ever faster acceleration and speed, more accurate positionning, longer life, a need that
even modern sophisticated ball screws could not supply efficiently.


Satellite roller screw became the muscle of choice for high speed machine-tools.
