STENHOJ has developed a unique UNIVERSAL dual broaching machine for soft- and re-broaching of internal splines. The required high speed broach operation is dynamically achieved by the use of electromechanical SERVO drives, securing the right acceleration and positioning during the broach operation. This special process is used only for high demand of accuracy and surface in the splines after hardening of gears and other high quality components. The usage of broaching oil and water soluble as coolant with additional fine filtration of the minor chips, guarantees the high quality required in this very special broach operation.
