5.3..Setting.the.cut.thickness.
5.3.1. Measurement of the cut height
The cut height above the loading surface of sections can be read on the scale on
the right side of the bridge in front of the control panel.
This scale you will use for the layout of cuts and for measuring the thickness of
prisms greater than 100 mm.
When setting the thickness of the cut off material you must add about 1.5 mm of
wastage.
5.3.2.. Thickness.setting.using.the.dial..
The cut off material thickness and the size of the saw cut wastage you
will set on the scale disc which is shown at the left side of saw on the
gear of the arm elevation. The disc is a two-scale of the board thickness
(the outer ring of 0-50 mm and an inner ring for a second revolution of the
wheel 50-100 mm) and a short scale on the opposite side from zero to set
a cut wastage. One division of the scale is 0.2 mm. The wheel can be, in
spite of the resistance of the frictional pad, manually rotated. The actual
size of the cut wastage depends on the saw band thickness, the size of
teeth distribution and partly on the type of cut wood. For the correct work,
measure the cut wastage within the first cuts with the new saw band. For
a rough estimate the cutting wastage can be calculated as:
For example, if the saw band thickness is 0.9 mm and saw setting 0.3
mm on each side, then the cutting wastage will be 0.9 + 2 x 0.3 = 1.5 mm
Procedure when using the measuring disc.
1. Set the saw band to the height where you want to make the first cut.
2. Rotate the measuring wheel so that, on the scale of cutting wastage to the left from zero, was 1.5 mm
3. Make the first cut.
4. Lift the arm above the cut piece of material and return back to the bridge in front of the material being cut.
Do not move with the scale
5. Remove the cut board.
6. Lower the arm down until the scale indicator shows you the desired thickness of the other board.
7. Turn the scale to the right and set the cutting wastage.
8. Make a cut.
9. Repeat the process from point 4 for other cuts.
