The Hole locator Gauge can be set to hold the Hole
Punches at a constant distance from the edge of the
workpiece. The gauge is held in place by one or two
socket head caps screws. Before making any adjustment,
first, unplug the power cord. To adjust the position of the
gauge, loosen the cap screw(s), tap the gauge into the
desired position and retighten the cap screw(s).
HOLE LOCATOR GAUGE ADJUSTMENT
All models can be used with an accessory work stand for
bench or table mounting of the Hole Puncher. The stand
is standard with all models. To install the stand, first
unplug the power cord., then mount the unit to the stand
with the supplied hardware.
When using the stand, periodically check to make sure that
the punched material (slugs) are not stacking up between
the exit hole in the "C"-frame and the stand. Keep this area
clear of accumulated slugs.
USING THE WORK STAND
SELECTING PROPER DIES
Proper die selection is essential. Other than the obvious
necessity of matching shaped punches and dies, there are
two other basic selection factors that must be considered.
The first is die clearance. Different material types and
different material thicknesses require different clearances
between the punch and die. In order to maintain the best
possible hole while remaining within the tonnage
capacity of the machine, it is essential to choose the die
with the proper clearance. The second is the die angle.
Most structural shapes can be punched with the standard
flat dies, but "I" -beams and most channels which
have a 2-in-12 taper require the use of special
9-1/2 degree angled dies. Car and ship channel
flanges and other structural shapes with a 2 degree
taper can be punched with flat dies. Materials with
a flange taper of less than 5 degrees can also be
punched with the flat die, however, the hole will be
slightly angled. Refer to specific information and
tables within this manual for the proper punch and
die combination.
Hougen-Ogura Punches are designed to be used in
Structural Steel. If used in harder or higher tensile
strength materials, performance will be impeded and
serious damaged could occur to your unit.
