Die selection
Depending on the thickness, tensile strength and type
of material being worked, one of the 3 following die
types can be used:
Die types with ordering numbers Fig. 9431
Die type 5 7 P7
Material thick. (mm) in flat
sheets
Aluminium 250 N/mm²
Mild steel 400 N/mm²
Stainless 600 N/mm²
Stainless 800 N/mm²
3-5
3-5
3-5
max. 2.5
> 5-7
> > 5-7
-
-
> 7-10
-
-
-
Material thick. (mm) if working
with "profiles", i.e. workpieces
with folds up to 90°
3 (2.5) > 3-5 > 5-7
Use highest possible dies
Distance between die and punch guide Fig. 16811
Ensure that the distance X is as small as
possible!
Extreme up and down movements (wobbling) may
occur during the cutting process if an incorrect die is
used.
Result: •
excessive tool wear
•
increased load on the machine
Remedy:
•
use the highest die whenever
possible
See Fig. 16811
Punch selection
Two different punches may be used to machine
sheets with various tensile strengths:
Punch type Standard punch Punches for high
tensile sheets
Order No. 104589 104590
Tensile strength of
material up to 400 N/mm² greater than
400 N/mm²
