5.2.2 Multiple step cutting
Multiple step cutting consists of moving the conveyor cart with the material to be cut back and
forward under the rotating blade,
•
Place the material to be cut on the conveyor cart firmly against the guide-a-cut and the
backstop, keeping the hands well away from the blade.
•
Move conveyor cart forward near the blade and pull down the cutting head until blade is lowered
to a point where it will lightly contact the surface of the material.
•
Then pass the material beneath with rapid full length strokes, taking a shallow cut
(approximately 3 mm deep as shown on the picture) on the forward. On the backward stroke, lift
the blade just clear over the cutting line.
•
Complete each rapid stroke backward and forward by passing the material beyond the centre of
the blade before starting the reverse movement of the conveyor cart.
NOTE: the harder the material, the more rapid should be the forward and backward strokes.
Step cutting lessens the area of the blade circumference in contact with the material, keeping the
blade cool, running free and cutting at peak efficiency.
5.2.3 General advice for the cutting
•
Material weight under 15 kg and having dimensions smaller than 500x500x110mm can be cut
with the machine.
•
Before commencing work make sure tools are firmly seated!
•
Select the right tools as recommended by the manufacturer depending on the material to be
worked, the working procedure (dry or wet cut) to be carried out and the required efficiency.
•
Apply cooling water continuously whilst cutting and in good time! Make sure the water pan
contains enough water.
•
When dry cutting, ensure sufficient dust extraction and wear a dusk protection mask!
•
When cutting work is finished, close the water-tap so you can remove the cut pieces from the
conveyor cart without getting wet.
•
In case the thermal protection trips, wait until the motor has cooled down before starting the
machine again.
