NOTCHING STATION
The threading station has quadrangles punch stamp as a standard equipment element and is
delivered with a threading table complete with adjustable lateral and rear counter holders, which
essentially simplify the repeatable positioning of the material.
The sharp notching tools can also be constructed at this work station. Optionally, the units for
narrower width of quadrangles or forms can also be delivered. Various units are also available for the
forming of bar ends.
A special feature of this work station is the possibility to fix some punch end units, that means
tools for smaller punching works up to a punch pressure of 40 t ( characteristics can be supplied upon
request ).
In case the grinding of the notching stamp is necessary, only grind the side and front surfaces
of the stamp. The matrixes have four cutting edges and should be turned in order to require
new cutting.
