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
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
N Mark cutting line(A)
N Work along the cutting line. When
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 5 to 6cm. Cut thicker
material in multiple operations
Cutting plates

surface, sandbed)
N Grind a guide groove(A) along the
line marked
N Make the cut(B) deeper

so that no material breaks away
N Break plate
N Make curves in multiple operations
– make certain that the abrasive
wheel does not tilt
Cutting pipes, round and hollow bodies
N Secure pipes, round and hollow
bodies against vibrations, slipping
and rolling away
