MLW100 Z



Tube multiple stations wet finishing and polishing machine – MLW100 Z, available with 2 stations (MLW100 2Z), 3 stations (MLW100 3Z) and 4 stations (MLW100 4Z), is equipped with ML planetary system and enables a faster tube finishing work than single stations machines.

Automatic work set-up and control of all the information about the tube finishing is done in a mobile panel with integrated touchscreen. Tube finishing stations are completely independent. Final finishing of the round tubes is possible in one pass only.

The wet system enables a faster cooling of the tube as well as the possibility of working different metals simultaneously such as aluminum tubes, stainless steel tubes, steel tubes.
