English
If fumes or smoke are anticipated (e. g.,
when cutting composite materials), wear
respiratory protection.
Composite resin abrasive wheels
suitable only for wet cutting
Use abrasive wheel only
with water.
To bind dust, the abrasive wheel must
be supplied with at least 1 liter of water
per minute. To avoid a reduction in
cutting performance, the abrasive wheel
must be supplied with not more than
4 liters of water per minute.
After using the abrasive wheel, the
wheel should be allowed to continue
spinning at operating speed for
approx. 3 to 6 seconds without water in
order to spin off the water remaining on
it.
Observe with diamond and composite
resin abrasive wheels
Objects to be cut
Must be fully supported
–
Must be secured so it cannot roll or
–
slip off
Must be prevented from vibrating
–
Severed parts
With openings, recesses, etc., the
sequence of the cuts is important.
Always make the last cut so that the
abrasive wheel does not become
52
jammed and so that the operator is not
endangered by the severed or
separated part.
If necessary, leave small ridges that hold
the part that is to be separated in
position. Break these ridges later.
Before finally separating the part,
determine:
how heavy the part is
–
how it can move after separation
–
whether it is under tension
–
When breaking out the part, do not
endanger assistants.
Cut in several passes
Mark cutting line (A)
N
A
Work along the cutting line. When
N
making corrections, do not tilt the
abrasive wheel, but always set the
abrasive wheel against the
workpiece anew – the cutting depth
for each operation should not
exceed 2 cm. Cut thicker material in
multiple operations
Cutting plates
Secure the plate (e. g. on a non-slip
N
surface, sandbed)
Grind a guide groove (A) along the
N
line marked
Make the cut (B) deeper
N
Leave a "hinge" (C)
