Die selection
One of the following three die types may be selected
depending on the thickness, tensile strength and
type of workpiece that is to be machined:
Die types with ordering numbers Fig. 9778
Die type 7 10 P10
Material thickness (mm) for flat single rolled sheet
Aluminium 250 N/mm² > 5-7 >7-10 >10-12
Construction steel 400 N/mm² > 5-7 >7-10 -
Special steel 600 N/mm² > 5-7 - -
Special steel 800 N/mm² - - -
Material thickness (mm) for
machining „profiles“, i. e.
workpieces with edges up to 90°
5 > 5-7 > 710
Using the highest possible die
Distance between the die and the punch guide Fig. 16802
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. 16802
Punch selection
Two different punches may be used to machine
sheets with various tensile strengths:
Punch (standard)
to machine materials
up to 400 N/mm²,
e.g. mild steel
Order no. 112900
Punch for high-tensile sheets
to machine materials
greater than 400 N/mm²,
e.g. chrome steel
Order no. 120344
