  • Roll tool for cold pilger rolling of pipes
    Patent number: 5450741
    Abstract: A roll tool for cold pilger rolling of pipes in which the reducing zones of the two tool grooves, starting from the transition from the reducing zone to the smoothing zone, have transitional areas without kinks which extend parabolically. The curve describing the mandrel groove runs parallel to the parabolic transitional area of the roll groove proceeding from the location of the narrowest gap between the roll and mandrel while forming a wall smoothing zone.

  • Making of pilger roll
    Patent number: 4238205
    Abstract: The grinding wheel and roll are particularly positioned to each other on the basis of parameters representing the local slope changes of the roll groove and its deviation from a semi-toroidal groove. The grinding wheel can be moved in two orthogonal directions, one being transversely to its normal orientation, but needs tilting therefrom while the roll is moved transversely to both directions. Digital control moves the parts into the desired positions.
