3 Sample Applications
3.2 Severed parts
With openings, recesses, etc., the sequence of
the cuts is important. Always make the last cut
so that the diamond abrasive chain does not
become jammed and so that the operator is not
endangered by the severed or separated part.
If necessary, use wedges and if necessary, leave
small ridges that hold the part that is to be sepa‐
rated 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.

tle.

► Work along the cutting line. When making cor‐
rections, do not tilt the diamond abrasive
chain, always reposition it afresh
3.5 Cutting round and hollow bod‐
ies
► Secure pipes, round bodies, etc. against roll‐
ing away
► Mark a cutting line - when determining the cut‐
ting line, avoid reinforcement, especially in the
direction of the severing cut
► Make the plunge cut very carefully
► Feed with full cutting depth along the cutting
line – for small corrections of direction, do not
tilt the diamond abrasive chain, but always
position it anew instead – if necessary, use
wedges and if necessary, leave small ridges
that hold the part that is to be separated in
position. Break these ridges later
