OPERATION MANUAL
5.2 SETTING THE BLADE GAP
Check the maximum cutting capacity of the guillotine..
This can be found on the specification plate on the
machine. The capacity listed is for Mild Steel. Stainless
steel capacity can be found in the specification table in
this manual. (Page 4)
Check The Blade Gap Setting
The machine is supplied from the factory with the blade
gap set to the capacity of the machine.
When cutting large runs of material the blade gap should
be set to that thickness.
The blade gap should be approximately 10% of the
thickness of the material.
E.G. 1mm material = 0.1mm Blade Gap
2mm material = 0.2mm Blade Gap
Adjusting the Blade Gap.
There are two points that need to be adjusted to be able to
change the blade gap on these machines. These are found
on each side of the blade beam, and are accessed from the
rear of the machine.
To adjust the blade gap,
1. Loosen the 4 bolts on both sides of machine, (Fig. 5.5)
Both sides need to be loosened before any adjustment
is made.
2. Set the selector control on the control box to “INCH”
Depress the foot pedal at short intervals (INCHING)
until the blades on the right hand side are about to
pass. If! No danger of the blades clashing continue
“inching” the machine,
3. ISOLATE THE MACHINE FROM THE POWER SUPPLY.
4. Using a feeler gauge between the blades adjust the
gap using the nuts on the centre stud inside the
machine on either end of the side plates.(Fig. 5.6)
5. Tighten the four bolts on both sides of the machine.
6. Using a test piece take a cut and check the gap again to
ensure it hasn’t moved
