State-of-the-art machining and production lines with over 80 mostly CNC-controlled machines

According to the products and their dimensions the manufacturing steps, turning, milling, boring, grinding, hardening, finishing, dynamic balancing and packing are efficiently installed. Specialized departments carry out the machining of fluidly heated thermal rolls. Special methods to guarantee the roll geometries under operating conditions are applied here.

Seal testing to determine the pressure stability and warm balancing for optimal running properties of the rolls are carried out here.

Especially for plastic calender rolls a surface roughness of smaller 0.01 µm and a concentricity accuracy of 1 µm are achieved.



  • CNC-controlled turning-, milling-, grinding-, drilling-, and balancing machines in 12 processing halls
  • Approx. 1.500 tons finished products per month

Finished measurements

  • max. barrel length up to 13 meters
  • Ø over 1,700 mm
  • 100 tons finished weight.
