The notching station has a rectangular punch as standard fitting and is supplied with a notch
table complete with adjustable side and back stops which allow repetitive material
positioning.
Vee notch tooling can be fitted at this work station, or alternatively units can be supplied for
narrow widths of rectangular or vee shapes; units also available for bar end shaping.
A particular feature of this work station, provides for some punch end units to be fitted.
When notch punch requires sharpening, grind side and front faces of punch only.
The dies have four cutting edges and should be turned to present new cutting edge.
To adjust dies after punch grinding:
1.
Slacken bolster fixing screws and position locking screws.
2.
Move bolster into new side and front position on punch;
one side of bolster is adjustable on the die.
3.
Clearances between punch and die faces should be maintained as follows:
........at sides of punch
4/1000
’’
........at front of punch
12/1000
’’
Adjust bolster on the two faces accordingly and retighten fixing screws -
check clearances.
4.
Release adjustable die blade fixing screws and adjust blade to punch,
tighten fixing screws and check clearance.
5.
Ensure fixing screws are tight and that the positioning locking screws have been reset.
WHEN ORDERING SPARE PUNCHES AND DIES, ALWAYS QUOTE -
MODEL, TYPE AND SERIAL NUMBER OF MACHINE.

1.
The quality of cut is an immediate indication of the condition of the tooling.
Keep sharp, keen cutting edges.
2.
Check that the notched blank ejects after notching operation, thus avoiding
any ‘build up’ of slugs.
3.
Stay within the rated capacity of the machine.
