About MLW200

MLW200 round tube finishing machine finishes and polishes round, oval and elliptical tubes, straight or curved, up to Ø205mm with water cooling.

The ML planetary system enables the work without rotating the tube, delivering the best results on bent and curved tubes as well.

The auto feeding system transports straight tubes safely and automatically through the finishing station, enabling a consistent and high productive finishing quality.

The wet system enables a faster cooling of the tube as well as the possibility of working different metals simultaneously.

Minimum tube vibration even on the biggest lengths

With the ML Planetary System the tube is not spinning. The abrasive belts rotate around the tube while it is safely transported by the feeding systems.

Wet cooling system

Enables to reduce the temperature of the tubes during finishing operation and to keep dust away from grinding area, filtering it. Water cooling system in closed circuit. After being sprayed to the finishing area the water is filtered and pumped back to the machine. The automatic option provides a continuous renovation and monitoring of the filter paper cleanness, avoiding the operator to control this task.
