MC400 BENDING MACHINE INSTRUCTION BOOK 8
4.5. Principles to bend

The activation of the machine engine is carried out by usingthe pedals, one to turn right and the
other one to turn left, without nailing in.

It is necessary to get the side rollers up or down in order to regulate the bending radius, and do the
same with the vertical rollers in order to achieve the torsion.

Activation pedals have no nailing in. So the machine will stop when the pedal is not pressed.

For the emergency stop, press the pedal emergency button.

The material can be put in the machine for both places. Use the upper handling to adjust the entran-
ce of material. Use the milimeter scale to indicate the position.

Adjust the approximate height to both lateral rollers to get a given radius, (the more you do it , the
more experienced you will get).

Adjust the two vertical stand rollers. This will be adjusted by tha back part, getting them closer or
farther from the profile that has been already set in the rollers. They will help us control the lateral
distortion. (They must be adjusted so they get to slightly touch the profile).

If the profile to be worked does not fit in the rollers, it is advisable to cut the extreme to give it a
wedge shape, to ease its entrance.

In case the desired results are not achieved, then modify the side rollers position and the vertical
ones.

The fastening nuts of the rollers must be only tightended with the hands stregnth.(no fastening
tooling is required to do that).

It is advisable to put some oil in the up and down threads of the rollers whenever necessary to avoid
them from getting any hardness.
