The MF6i-50 is driven with three pneumatic motors or two hydraulic motors. The air supply of the pneumatic drive is done with a safety-turning valve, to operate the motor. By throttling the air supply, the motor speed can be controlled.
The machine is fixed in the pipe through self-centering sleeves 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 and can be regulated very accurately. The handle bars should be detached for the transport. It is prohibited to use them to lift the machine. For transportation purposes, the machine is equipped with two side bars.
Several tools that can be used are HSS tool bits or inserts with insert holder, which are clamped in a tool holder adapted to the processing size. To cover the whole area from 280 - 711 mm ID only one sleeve and one blade holder are required.
