3 MACHINE DESCRIPTION
The CROWN is a professional machine designed for cutting tubular keys. The main parts of the machine
are described below:
S AFETY DEVICE
The device is connected to a power plug with a differential switch. It activates the key-cutting machine
when the illuminated START button (R) is pressed and cuts out when the STOP button (S) is pressed.
M ASTER SWITCH
The master switch (A) with which to start the induction motor is situated on the front of the key-cutting
machine, on the right.
M OTOR UNIT
The CROWN key-cutting machine has a direct drive motor. The shaft/cutter unit is protected by a cover
(D).
M OBILE UNIT
The mobile unit comprises a slide (E) and an adjustable wedge (H).
The slide moves by lever (F) which returns to the idle position by means of a return spring located under
the slide.
The height of the wedge can be adjusted by means of a knob (G), which is also used to lock the wedge
in position.(G1)
K EY - CUTTING UNIT
The key-cutting unit comprises the operational parts of the machine, which work together to read and
reproduce the key.
• Cutter
A cutter with cylindrical hold (C) is the part of the key-cutting machine used to cut the key blank. It is
made of super rapid steel and has four cutting edges.
• Tracer point
The tracer point (B) is used for reading the original key and is located on the right-hand side of the
machine.
• Device
The device installed, in this case a T10, is used to seat the key to be copied on the right and the key
blank to be cut on the left.
Devices may vary according to the type of key to be cut. Their names, installation and operation are
described in this manual (see cap.10 a pag.15).
