9.5 CUTTING ANGLES
To make cuts at fixed angles (45° external, 90°, 45° internal) and at intermediate angles, the electronic
control must be used following the instructions given in the documentation enclosed with this manual for
the electronic equipment fitted to the machine.
9.6 CUTTING PROCEDURE
To proceed correctly with cutting operations certain basic rules must be followed.
Check
- Start the motors (just one impulse – stop immediately ) and check that the blades are rotating in the correct
direction.
- Check that the atomising flow is sufficient, if not adjust it following the instructions given in the specific
paragraph.
- Check that the profile bars show no evident signs of twists along their length, as the clamping tends to
straighten them. In actual fact the profiles remain defective and the twist returns as soon as the vices are
released after cutting, so the pieces obtained cannot subsequently be used for assembly.
- Check that the thickness of the profiles is within the tolerance, as in angled cuts in excess of 90° the
differences in thickness create errors in determining the length of the piece to be cut.
9.7 SAW BLADE
One last but very important piece of advice on cutting is the choice of blades. The machine is actually calibrated
for a blade thickness of 3.4 mm. and a tooth thickness of 4.1 mm. (Ø 550), for a blade thickness of 3.2 mm.
and a tooth thickness of 4 mm. (Ø 500), for a blade thickness of 4 mm. and a tooth thickness of 4.7 mm. (Ø
600).
If these thicknesses are changed, automatically the fulcrum of the heads is altered and therefore the cutting
measurement. Non sharpened blades can also vary the fulcrum of the heads. These points must obviously
therefore be borne in mind.
For these reasons we recommend that only our blades are used as they offer guarantees of quality control,
balance, choice of materials used and design.
Furthermore the use of adapter rings applied to the blade hole is PROHIBITED. Only blades with a hole diameter
as shown on the machine ID plate must be used (Ø 32 mm. for blades Ø 500 and Ø 550, Ø 40 mm. for blades
Ø 600).
N.B. Use only blades that conform to EN 847-1 standard.
