Components and functional parts

2.4.1 Electric circuit
The main components of the electric and electronic
circuit are as follows:
1
Mains socket: Mains filter with fuse and switch.
2 Connection strip: Base for connections.
3 position switch: Fast speed, stop and slow speed.
3
Light: Lighting of the work area.
4
Motor: Single phase with brushes.
5
Switching on and off of lights: Operates the plate for
6
calibrating the milling cutter and switches off before
cutting keys.
7 Adjustment plate: Plate with two red lights to calibrate
the milling cutter.
Milling cutter: Cutting tool to duplicate the original key.
8
Tracer point: Traces the original key.
9
Clamp: Two clamps to hold the original key and the
10
blank to be cut.

2.4.3 Clamps

The features of the DAKAR key cutting machine
clamps are superior to those of normal machines on
the market, because they have two separate securing
faces on the same clamp. The clamps can be positioned
at any position between 0º and 45º.
2.4.4 Springing and locking of slide on "x" axis
This spring system is used to carry out lateral milling of
waves keys.
Locking on the "X" axis is used to mill and make points
on a straight line on the "Y" axis.

2.4.5 Elastic or locked tracer point

The tracer point is the left axis of the machine looking
from the front. This tracer point has different applica-
tions depending on the work to be done:
Elastic tracer point
1
The elastic tracer point is used to carry out cutting
operations with vertical feed. Cutting by points.
2
Locked tracer point
When the tracer point is locked, cutting operations
with horizontal feed are carried out.

2.4.6 Vertical adjustment of the tracer point
Before starting the machine with the general switch,
position the two keys in the clamps. The original key
in the left-hand clamp and the blank in the right-hand
clamp. Activate the electronic control by pressing the
on/off button and adjust in the following way:
• Turn the locking handle 180º (to lock the tracer point)
• Lower the head and rest the tools without pressure
on a flat part of the key.
• When the tools come into contact with the key one
of the three indicators on the keypad will come on.
Left and right hand red lights
1
If the both red lights come on, the machine is adjusted.
The key, tracer point and milling cutter are touching.
Left-hand red light
2
If the left-hand red light comes on, the tracer point
is touching the key. It has to be adjusted. To do this,
turn the wheel R to the left until the both red lights
come on.
Right-hand red light
3
If the right-hand red light comes on, the milling
cutter is touching the key. It has to be adjusted. To do
this, turn the wheel R to the right until the both red
lights come on.

2.4.7 Changing the milling cutter and tracer point

To release the milling cutter, first of all you have to lock
the shaft by pressing the locking button and turning the
bit-holder with your hand until you find the locking hole
on the shaft.
After locking, release the bit-holder and change the
milling cutter. When inserting this, it must go right in
the bit-holder.
To release the tracer point, secure the bit-holder and
change it. When the tracer point tool is inserted ensure
that it goes right inside the bit-holder.

2.4.8 Speed and light switches

In the right side of the machine there are two switches,
one of them has three positions (I, 0, II) for the speed of
the milling cutter and the other has two positions (0, I).
The first switch is for the speed of the milling cutter
( slow speed, stop and fast speed) and the second switch
turns on or turns off the light.
