CARRIAGE OVER TRAVEL DEPTH ADJUSTMENT
Your key machine is equipped with a depth over travel device. Its adjustment is important. The over
travel device prevents the cutter wheel from cutting into the vise jaws when there are no keys clamped
in the machine. Setting the depth over travel device too high will prevent deep cuts from being made
- they will not get cut all the way down into the key blank.
To adjust the depth over travel you will need:
v
Slot Head Screwdriver
v
7/16 Wrench
v
Three pieces of writing paper - cut to approximately 1 x 4 each.
Close both vise jaws without keys in them. Release the carriage and position it so the stylus and
cutter wheel are in about the middle of the vise jaws.
Loosen the 7/16 Hex Jam Nut on the front of the carriage.
Loosen the ¼ 20 slotted screw stud with your screwdriver. About 1 turn should be enough.
Observe that the stylus is touching the face of the closed vise jaw.
Gently turn the slotted screw stud with your screwdriver in the clockwise direction and stop when
you feel the stud contact the key machines main housing. There is a 3 long hardened roll pin in
the machines main housing that the slotted screw stud will contact.
Turn the slotted screw stud an additional ¼ turn after contacting the roll pin the machines main
housing. The thread pitch is 20 which is approximately 12 thousands of an inch per ¼ turn. Tighten
the 7/16 Hex Jam Nut on the slotted screw stud - use moderate tightness.
After tightening the 7/16 not - check the gap between the stylus and the face of the closed vise
jaws. Use three pieces of 1 x 4 writing paper you made earlier. They equal a combined thickness
of about 9 thousandths of an inch. Readjust if necessary.
IMPORTANT:
Carriage over travel will work only when adjusted properly. The following things
can happen if the adjustment is not done properly.
a)
If adjusted to low your cutter wheel may cut into the right-hand vise jaw.
b)
If adjusted to high your cutter wheel may not cut deep enough when cutting deep cuts in
keys.
c)
Carriage over travel will not prevent cutting the right-hand top vise jaw if the top vise jaw
has come loose and has moved forward into the cutter. PLEASE check the tightness of the knurled
knobs OFTEN.
