|In view of carrying out a costant product development, expecially
on those products where no technical innovations are due, we have
managed to increase the efficiency of our mechanical speed variators
by reducing the heat dissipation during operation. This has all been possible by working out an additional operation
on the components after grinding : the finishing by
chemically accelerated vibrations.This new process makes surfaces uncomparably good in reducing friction,
wearness as well as contact fatigue and dynamics.
