4.5.3 EMERGENCY SWITCH FOR STOPPING THE MILLING CUTTER
To prevent accidents, this automatic key-cutting machine is equipped with an emergency
switch, located on the front right part of the machine.
In case of emergency, block this switch to stop the cutter from turning. The cutter will
stop immediately, although the slide will continue to move forward until it has finished
the coding cycle.
If the slide should hit an obstacle, the motor controlling it will require extra power to
move the slide, and the slide will stop. It will continue working when the obstacle is
removed.
NOTE: While the emergency switch is blocked, the milling cutter cannot be turned (by
starting a coding cycle or by pressing the button that works the plane). If you wish to
continue using the machine (turning the milling cutter), the emergency switch must the-
refore be unblocked.
See figure 4
4.5.4 4-SIDED CLAMP
The clamp is designed to secure different types of keys on each side. The image (Fig.5)
shows the copying possibilities on each of the sides of the clamp.
1) The copying of a key with support on the blade:
Side 1: Keys with regular bit.
Side 2: Keys with narrow bit.
2) The copying of a key by trunnion on the guide (profile):
Side 3: Keys with a guide on the lower part.
Side 4: Keys with a guide on the upper part.
3) The copying of NEIMAN-type keys by trunnion on the guide. (Fig. 6)
5.- HOW THE MACHINE WORKS
5.1 MACHINE ADJUSTEMENT
The ECCO-AUTOMATIC copying machine has 3 types of adjustment (Lateral, Depth of
cut, and Positioners).The copying machine is supplied with three adjustments having
been carried out, as these are determined during the assembly stage of the machine.
Only in exceptional cases will the machine need a lateral adjustment or an adjustment
of the positioners. In contrast, each time the cutter is changed a depth of cut adjustment
must be carried out if optimum copying quality is to be gua-ranteed.
5.1.1 CONTROL AND SIDE ADJUSTMENT
• Secure the adjustment keys (2) on face no. 1 of the clamps, going as far as the tip stop
plates (3) (with these inserted into the groove located further to the right).
• Unblock the slide and bring the clamps near to the copying index (I) and the cutter (F).
To do this, the steps below must be followed:
- Start the cutting cycle.
- When the feeler touches the bit of the key, turn off the machine by activating the
general switch located at the back.
- At this point, unplug the power cable as a safety measure.
• Bring the clamps with the adjustment keys (2) towards the copying index (I) and the
cutter (F), in such a way that the adjustment keys are correctly positioned regarding the
copying index and the cutter.
• If the notches of the adjustment keys do not duly coincide with the copying index and
the cutter, proceed as follows:
- By loosening slightly the studs (T) of the axis we can move the cutter to the right or to
the left. The cutter should be moved to a position in which it coincides on the notch of
the corresponding adjustment key. To carry out this operation it is necessary to release
the motor guard in advance.
- The distance is thus adjusted, with the copying index (I) and the cutter (F) coinciding in
the respective rebates of the adjustment keys. Secure the studs (T) of the axis.
• Finally, move the slide manually towards the furthest position on the left, and block it
12
by pressing downwards. Activate the general machine switch again. Take great care,
as when this switch is activated again the machine will start up instantaneously until
the cutting cycle that had been started before turning off the machine is completed.
See figure 7
NOTE: After a lateral adjustment, an adjustment of the positioners is always carried out.
5.1.2 CONTROL AND ADJUSTMENT OF THE CUTTING DEPTH
• Secure the adjustment keys (2) on face no. 1 of the clamps, going as far as the tip stop
plates (3) (with these inserted into the groove located furthest to the right).
• Unblock the slide and bring the clamps nearer to the copying index (I) and the cutter (F).
To do this, the steps below must be followed:
- Start the cutting cycle.
- When the feeler touches the bit of the key, turn off the machine by activating the
general switch located at the back.
- At this point, unplug the power cable as a safety measure.
• Bring the clamps with the adjustment keys (2) towards the copying index (I) and the cu-
tter (F), in such a way that the adjustment keys rest on the copying index and the cutter.
• Turn the cutter by hand. If it touches the adjustment key slightly, the machine is co-
rrectly adjusted.
• If when the cutter is turned it moves freely without touching anything, this indicates
that the cutter is retarded in relation to the feeler and that the machine cutting is insu-
fficient. On the contrary, if the cutter is blocked at the adjustment key, this means that
the cutter is ahead of the feeler and that the machine cutting is excessive.
• If any of these incidents occur, proceed as follows:
- Release the stud (L) blocking the copying index (I) and turn the micrometric screw (H).
- Advance or retard the copying index until the cutter turns and touches the adjustment
key slightly. Then tighten the screw (L) of the copying index and the machine will be
operating perfectly.
• Finally, move the slide manually towards the furthest position on the left, and block it
by pressing downwards. Activate the general machine switch again. Take great care,
as when this switch is activated again the machine will start up instantaneously until
the cutting cycle that had been started before turning off the machine is completed.
See figure 8
5.1.3 CONTROL AND ADJUSTMENT OF THE POSITIONERS
• The left face of the positioner on the right-hand side (P2) must coincide with the left-
hand side of the cutter (F) when the slide is to the extreme right; these sides of the
cutter and the positioner determine the start of the copying cycle for the key. In order
to carry out this adjustment, follow the steps below:
- Turn off the machine by using the general switch to the rear.
- Unblock the slide and move it manually to the extreme right; release the slide when
this position is reached.
- On supporting the tip stop plate (2) on the lefthand side of the cutter (F), the left-hand
side of the positioner (P2) must coincide with the tip stop plate (2).
- If this does not occur, release the stud (T2) securing the positioner (P2) and secure it
again in its correct position.
• The distance between the right positioner (P2) and the left positioner (P1) must coinci-
de with the distance between the cutter (F) and the copying index (I). In order to carry
out this adjustment therefore, follow the steps below:
- Keep the machine switched off and the slide in an extreme right-hand position.
- On supporting the tip stop plate (2) on the lefthand side of the copying index (1), the
left-hand side of the positioner (P1) must coincide with the tip stop plate (2).
- If this does not occur, release the stud (T1) securing the positioner (P1) and secure it
again in its correct position.
• Finally, replace the slide in the rest position.
See figure 9
5.2 KEY CUTTING
When used correctly, the ECCO-AUTOMATIC copying machine is absolutely safe.
However, it should not be forgotten that the work cycle is automatic and does not
involve handling by the operator.
Therefore, if the copier should involuntarily move his/her hands too close to the work
area of the machine, there may be a risk of cut or crushed fingers.
In case of emergency, block this switch to stop the cutter from turning.
To work in total safety during the various copying stages, follow these instruc-
tions:
• Work with dry hands.
• The cutter guard should be in place in any copying operation.
• Use protective goggles.
• Make sure the machine is connected to earth.
• Do not move hands near the cutter when it is in operation.
• Only turn on the machine when slide operations have finished (secure key in the clamp,
etc.)
5.2.1 KEY CUTTING
• Turn the clamps in order to locate the correct blocking side of the key, according to the
type of key to be copied.
• Both the original key and the key blank should be introduced through the left side of
