2 Hybrid TurnControl 3D supercalender lathe modernizations at M-real Kirkniemi paper mill, Finland.

Two old supercalender cotton roll lathes (Poreba TR100 and Niles DLZ1000) were upgraded with 3D turning and 4-point measuring systems.

The high speed turning unit Hybrid PMU-12 compensates machine tool's bed error and roll's roundness error. The roundness error in soft sc-rolls can be over 150µm !

After modernization, the supercalenders operate more smoothly and the rolls last longer.
