3.2.5 cutting “aBloY” keYs
CARRIAgE ADJUstMENt
• Put two blank keys one in each clamp and check that both keys touch the milling cutter
(F) and the tracer point (i). if the milling cutter or tracer point do not touch, the carriage
needs to be adjusted in the following way:
• Undo the two “dovetail” screws on the carriage. You will then be able to move the
whole tool forward or back, until the milling cutter and the tracer point touch the keys.
• To stop the tip, ensure that one key touches the milling cutter and the other the tracer
point.
see figure 11.
3.2.6 cutting keYs With the carriage For making grooVes
Carriage adjustment
• Put two blank keys one in each clamp and check that both keys touch the milling cutter
(F) and the tracer point (i). if the milling cutter or tracer point do not touch, the carriage
needs to be adjusted in the following way:
• Undo the two “dovetail (EC-91)” screws on the carriage (EC-73). You will then be able
to move the whole tool forward or back, until the milling cutter and the tracer point
touch the keys.
see figure 12
4.- MAINtENANCE AND sAFEty
When carrying out maintenance operations, the following requirements must be met:
• Never carry out any operation with the machine switched on.
• The machine must be unplugged.
• The indications in this manual must be strictly adhered to.
• Only original spare parts must be used.
4.1 CHANgINg tHE MILLINg CUttER OR PLANE
undo the two screws on the milling cutter guard and remove the guard.
to change the milling cutter:
using the 2 size 18 spanners, lock the milling cutter shaft and undo the nut (k) – lefthand
thread – holding the milling cutter in place (F). then replace the milling cutter, and finally
put the milling cutter guard back into place.
to change the plane:
lock the milling cutter shaft using the size 18 spanner. undo the screw (r) using an allen
key. replace the plane and then put the milling cutter guard back into place.
see figure 13
4.2 tRACER ADJUstMENt
When replacing the machine’s tracer, it is advisable to perform a series of adjustments
to ensure that the quality of duplication is not affected.
For machines with Ford and/or aBloY and/or regata carriages, it is sufficient to per-
form the conventional depth and sideways adjustments which are explained in detail in
the machine’s instruction manual.
For machines with a comBi carriage, in addition to performing the conventional depth
and sideways adjustments, it is advisable to adjust the “tracer plate” beforehand in
order to ensure a correct duplication of the teeth of gorJa type keys.
this adjustment is performed as follows:
• Secure the adjustment rods (V), in each of the clamps.
see figure 15.1
• Gently loosen the screws (T) which secure the “tracer plate” (C) to its support (S), in
such a way that it is only lightly secured. make sure that the rear part of the “tracer
plate” is resting firmly on its support.
• Move the rods nearer to the most protruding point of the tracer-milling cutter. In this
position perform the depth adjustment of the tracer with the help of the knurling wheel
(r). see figure 15. 2
• Next, manually turn the milling cutter to check that it scrapes against the adjustment
rod (V) with the same intensity in the upper carriage rotation position ( see figure
15.3 ), as in the lower ( see figure 15.4 ). n.B. perform this check on the area to the right
of the clamp, which is the side where the key comBi is normally. if the milling cutter
scrapes against the rod with the same intensity on the upper part as on the lower part,
the adjustment of the “tracer plate” is complete. if not, proceed as follows:
1.- if the milling cutter scrapes against the adjustment rod (V) more intensely when the
carriage is in the upper position: carefully move the “tracer plate” upwards by gently
knocking it in an upwards direction.
2.- if the milling cutter scrapes against the adjustment rod (V) more intensely when
the carriage is in the lower position: carefully move the “tracer plate” downwards by
gently knocking it in a downwards direction.
• When the adjustment of the “tracer plate” is complete (C), secure it to its support
(s) by means of the screws (t). ensure that the rear part of the “tracer plate” is
resting firmly on its support.
4.3 sAFEty RECOMMENDAtIONs
1.- do not try and start or use the machine until all safety matters, installation instruc-
tions, operator guides and maintenance procedures have been fulfilled and understood.
2.- always switch off the power supply before carrying out any cleaning or maintenance
operations.
3.- keep the milling cutter clean and free from filings, as well as the clamp support area,
so that the clamps do not jam.
4.- keep the machine and the area around it clean.
5.- Work with dry hands.
6.- use safety glasses, even if the machine is fitted with guards.
7.- ensure that the machine is properly earthed.
