Nibbling:
The special way
of cutting sheet metal
Another very efficient process for the cutting of steel metal sheets in addition
to laser cutting is "nibbling".
A large sheet metal panel is moved under a cutter head over a table with
sliding support. The cutter head cuts the outlines out of the sheet metal with
short cuts following fast on one another. The sheet metal is moved at speeds
of up to 60 meters a minute.
There is much less burr than with stamping so that there is also much less
reworking.
