  • Coolant delivery system and skiving machine equipped with the system
    Patent number: 9573234
    Abstract: A coolant delivery system which serves to deliver a cooling agent whose purpose is to carry away the heat that is generated in the process of machining a toothed profile by means of a skiving wheel rotating about its rotary axis. The coolant delivery system provides for a delivery path section which, seen in a projection onto a plane extending orthogonal to the rotary axis, is arranged closer to the axis than the toothed profile of the skiving wheel and has a dimensional component in the axial direction.
