Type WSN | Precision profile rolling mill

The WSN range is a further development of the WN type. The WSN type profile rolling machines are always used when profile wires need to be produced to the highest precision. The fundamental mechanical concept with surrounding frame and linear roll positioning with a wedge mechanism gives this machine a very high stiffness.

In the development of the WSN profile rolling mill, special emphasis was placed on short set-up times and reproducible settings in order to meet the requirements of flexible production.

Rolling mills of WSN type impress with extremely low maintenance requirements. All components are protected from corrosion by galvanization.
