3.1 Selecting the blade
Caution
Damage to property can result from improper blade
selection!
The quality of the cut will be severely impaired and the
individual tools will be overloaded.
¾
Use only appropriate tools.
The blade is notable for the following points:
•
Moving cutter blade (upper blade) and fixed cutter blade (lower
blade) are identical in shape and can be used interchangeably
(above or below).
•
All blades have 4 cutting edges.
•
They are non-regrindable "4-way multi-edge, throw-away
cutters".
Note
Two different blade types can be selected for the machining
process, depending on the sheet thickness or the tensile strength
of the workpiece.
Note
Standard blades with a tensile strength of
≤
400 N/mm² have no
special identification marking. Chromium steel blades are marked
with "Cr".
Note
For these reasons, it is highly recommended that only such tools
be used as those which correspond to the specifications contained
in this table.
