The MF5i is driven with two integrated pneumatic motors.The air supply of the pneumatic drive is done with a safety-turning valve, with which the motor is operated. By throttling the air supply, the motor speed can be controlled.
The machine is fixed in the pipe through a self-centering sleeve with exchangeable clamping jaws that act on the ID. The sleeve is operated with an attachable ratchet on the back of the machine. The feed of the milling spindle works manually by a star handle that can be regulated accurately.
The handlebars of the star handle should be removed from the machine for any transport purposes. Using them for transportation is prohibited. For this purpose, the machine is equipped with two side bars.
Different tools available are HSS blades or tool tips with tool tip holder, which are inserted into blade holders adapted to the processing size. To cover the whole clamping field from 100 – 460mm ID only one sleeve and one blade holder are needed.
