NOTE: Please note that all of our shaped punches, including squares, ovals, hexagons and special
order punches, are manufactured with a keyed alignment system. The keyed slot mates with slots
in the punch ram to allow two positive locked positions for the punch.
15. Place the insert back in the die holder and tighten the set screws.
16. Raise the punch retaining nut and turn it on to the punch ram. (The die holder may have to be
moved slightly to align the punch retaining nut to the punch ram.)
17. If you are using keyed punches, manually rotate the punch so that the key seats in the ram before
tightening the nut.
18. Tighten the punch retaining nut, using a wrench. Make sure that there is equal clearance on all
sides of the punch in the die.
NOTE: WHEN USING A HEAVY DUTY SPLIT-RING RETAINING NUT, AFTER THE NUT
HAS BEEN TIGHTENED, TIGHTEN THE BRASS BILLET SET SCREW AGAINST THE
THREADS OF THE RAM.
19. Re-tighten the bolts in the die holder.
20. Check to be sure of proper alignment. Realign, if necessary.
21. Return the stripper to the forward position.
22. Place the disconnect switch in the ON position and the selector switch in the START position and
power the machine.
23. Place the selector switch in the SHEAR position. To be sure that the clearance is correct, jog the
machine several times with the foot switch, without letting the punch come out of the die.
24. Place the selector switch in the PUNCH position.
25. Oil the punch and die before use and every 5 to 10 holes, thereafter. (For lubrication instructions,
SEE SECTION 5.1)
26. Punch three to five holes and re-tighten the punch retaining nut.
27. The punch and die alignment should be checked every two to three hours during the punching
operations. To do this, bring the punch down so that it enters the die. Turn off the machine.
Check and tighten the punch retaining nut, the bolt holding the die and the two bolts holding the
die holder. Check for equal clearance between the punch and die. Place the selector switch in the
START position and power the machine. Place the selector switch in the SHEAR position and,
using the foot switch, jog the machine several times to be sure of proper alignment.
B. CHECK ALL PUNCHING TOOLS FOR TIGHTNESS.
Tools should be checked at the start of each operation and intermittently during the workday.
Check the punch retaining nut, die, stripper and die holder. Tools tend to loosen under punching
shock. Keep them tight to prevent punch to die contact.
