Points to be Noted with Diamond and Composite Cutting Wheels Object to be cut - Must be fully supported; - Must be secured so that it cannot roll or slip away; and - Must be protected against vibration and movement. The cutting sequence There are many ways to cut materials and objects with a cut-off machine. The operator and/or his supervisor, with knowledge of the job site conditions and requirements, always must exercise good judgment and discretion in determining how to safely complete a cutting task. The methods described in the following sections, while constituting proven techniques, are illustrative only and are not meant to substitute for the judgment of the experienced workmen with direct knowledge of on-site conditions. However, the cutting sequence is important. The last cut must always be made in such a way that the cutting wheel cannot become pinched, bound or clamped and so that the operator, coworkers and bystanders are not at risk of being injured by a falling part that has been cut off or out, or by cutting debris or sparks. Leave small sections of uncut material to hold the part being severed in position. These sections can later be broken through manually, using a hammer or other appropriate tool. Always continue to wear appropriate eye protection when finishing a cut by breaking it manually. A number of points must be decided before the part is finally severed: - How heavy is the part? - In which direction can it move or fall after being severed? - Is it under tension? - Is it properly supported to prevent pinching or binding of the wheel? The operator, co-workers and bystanders must not be put at risk of injury when the part is broken off or falls. Cutting in several passes N Mark cutting line (A). N Work along the cutting line. If corrections are necessary, always lift the machine and reposition the cutting wheel, taking care to ensure that it is not wedged, tilted, twisted or side loaded. Attempting to change the position or direction of a cut while the wheel is in the cut can bind the wheel. This can lead to kickback, other reactive forces or a shattered composite cutting wheel, which could result in severe or fatal personal injury.The cutting depth per pass should not exceed 2" to 2 1/2" (5 to 6 cm). Thicker material must be cut in several passes. The maximum cutting depth for abrasive cutting wheels with a 12" diameter is 3.9 in. (100 mm). The maximum cutting depth for abrasive cutting wheels with a 14" diameter is 4.9 in. (125 mm). Cutting Slabs N Secure the slab (e. g. on a non-slip surface, sandbed) and mark the cutting line. 22 TS 410, TS 420

Points to be Noted with Diamond and
Composite Cutting Wheels
Object to be cut
–
Must be fully supported;
–
Must be secured so that it cannot
roll or slip away; and
–
Must be protected against vibration
and movement.
The cutting sequence
There are many ways to cut materials
and objects with a cut-off machine. The
operator and/or his supervisor, with
knowledge of the job site conditions and
requirements, always must exercise
good judgment and discretion in
determining how to safely complete a
cutting task. The methods described in
the following sections, while constituting
proven techniques, are illustrative only
and are not meant to substitute for the
judgment of the experienced workmen
with direct knowledge of on-site
conditions.
However, the cutting sequence is
important. The last cut must always be
made in such a way that the cutting
wheel cannot become pinched, bound
or clamped and so that the operator, co-
workers and bystanders are not at risk of
being injured by a falling part that has
been cut off or out, or by cutting debris or
sparks.
Leave small sections of uncut material to
hold the part being severed in position.
These sections can later be broken
through manually, using a hammer or
other appropriate tool. Always continue
to wear appropriate eye protection when
finishing a cut by breaking it manually.
A number of points must be decided
before the part is finally severed:
–
How heavy is the part?
–
In which direction can it move or fall
after being severed?
–
Is it under tension?
–
Is it properly supported to prevent
pinching or binding of the wheel?
The operator, co-workers and
bystanders must not be put at risk of
injury when the part is broken off or falls.
Cutting in several passes
N
Mark cutting line (A).
N
Work along the cutting line. If
corrections are necessary, always
lift the machine and reposition the
cutting wheel, taking care to ensure
that it is not wedged, tilted, twisted
or side loaded. Attempting to
change the position or direction of a
cut while the wheel is in the cut can
bind the wheel. This can lead to
kickback, other reactive forces or a
shattered composite cutting wheel,
which could result in severe or fatal
personal injury.The cutting depth
per pass should not exceed 2" to
2 1/2" (5 to 6 cm). Thicker material
must be cut in several passes.
The maximum cutting depth for abrasive
cutting wheels with a 12" diameter is
3.9 in. (100 mm).
The maximum cutting depth for abrasive
cutting wheels with a 14" diameter is
4.9 in. (125 mm).
Cutting Slabs
N
Secure the slab (e. g. on a non-slip
surface, sandbed) and mark the
cutting line.
