Adjustment and fine tuning

3.1.1 Adjusting of the cutting depth
Calibration should be carried out each time the tracer point
and milling cutter are changed.
To properly adjust the machine tools - tracer point and milling-
cutter - proceed as follows:
Put the corresponding tracer point and milling cutter in
1
the tool-holder, pushing them up until they will go no
further. In order to ensure minimum movement in the
adjustment operation, tighten the bit-holder so that
the tracer point and milling cutter are fixed in position.
Place two keys which are the same in the machine
2
clamps to complete the securing of the tools.
3 Remove the flexibility from the tracer point (turn the
butterfly nut on the left). Rest the tracer point and the
milling cutter on the keys in the clamps. When this is
done, the both red lights should come on. If one red light
should come on, make adjustments with the part above
the tracer point until the both red lights come on.

3.1.2 Tracer point flexibility

The tracer point can be located under the adjustment
position, when this tool is provided with flexible
movement. In the cutting operation, this location of
the tracer point enables it to be inserted gently into
each hole (perforation) of the original key, thereby
facilitating the milling of the copy, without any vibra-
tion or movement when the milling cutter comes into
contact with the copy. This will enable a precise copy
to be cut. The second speed is used for hard metal
tools.

3.2 Cutting keys

To cut keys safely the following regulations should be adhered to:
Work with dry hands.
Ensure that the machine is earthed.
Use safety glasses.
The machine should be switched off when keys are
put in and taken out of the machine.

3.2.1 Cutting SEA-1 keys

Position milling cutter and tracer points F-1 / P-1 (side) and
F-3 / P-3 (bit grooves).
Position them at the same height as indicated by the
lights. Insert them into the groove. Remove the flexibi-
lity from the tracer point and lock the milling cutter and
tracer point in the groove with the right-hand side lever.
Raise the tracer point a little so it does not take the key
with it. Insert the milling cutter in the right-hand side of
the groove and take it out from the left-hand side. Use
the side spring. 1st speed. See figure 11

3.2.2 Cutting OP-WH.P and OP-WY.P type keys

Put the keys into the clamps against the bar inserted
1
in the clamp groove. Use tooling nº 11 and place
them at the same height as indicated by the lights,
removing the flexibility from the tracer point.
Bring down the tracer point five degrees (turning
2
round to the right the tracer point adjuster).
NOTE: The five degrees measure depends on the
pressure made by the duplicator, if the pressure is
high, then increase those five degrees.
Insert the tracer point (and the milling cutter)
3
into the bit groove of the key. Lock the tracer
point in the groove of the key and the milling
cutter with the right-hand side lever, raising
the tracer point so that it does not take the
key with it. It is recommended to make first
an initial bitting on the key and then a second
one following the the profile of the key. The
mechanisation will be made from the tip of the
key towards the head. Use the side spring. 1st
speed. See figure 12
3.2.3 ME-3.P and ME-4.P type keys
Use adapter AD-MM (see drawing), tracer point and milling
cutter n.º 11. Position the adapter on the clamp. Put the two
keys in place and position them at the same height. Adjust
using lights with end butting against adapter. Insert into the
groove. Remove the flexibility from the tracer point. Lock
the milling cutter and the tracer point in the groove with
the right-hand side lever. Raise the tracer point a little so it
does not take the key with it. Make the first cut. As the keys
are reversible, only turn the duplicate. Loosen the clamps,
remove the key and put it back the other way around.
Tighten the clamps and make the second cut.
Use the side spring. 1st speed.
See figure 13
3.2.4 Cutting KA-2, KA-3 and KA-4 keys
Put the keys into place, release the clamps, put the angle necessary
into place depending on the type of key and tighten the clamps.
Warning:
- The cut points of the KA-3 key must always be at the
bot tom of the clamp.
1st speed.
- The cut points of the KA-2 key must always be at the
top of the clamp.
1st speed. See figure 14
3.2.5 Cutting WIN-1D, WIN-2D, WIN-3D and WIN-4D keys
Use tool n.º 15. Adjust on two flat key blanks. Then place
the key with teeth facing upwards in the correct position
(as indicated by the drawing). End of key as far as it will go.
Remove the flexibility from the tracer point. With the machi-
ne in operation, insert the tracer point precisely in one of the
points. Lock the milling cutter and the tracer point with the
right-hand side lever and proceed with cutting. 1st speed.
See figure 15
