Components And Functional Parts; Operation And Functions; Key Cutting - JMA CAPRI User Manual

- Display-keypad master switch: Turns the display-keypad features on and off.
- LED indicator:
This is red when the machine is running. But the display-keypad features
are off.
It will be green when the machine is running and the display-keypad featu-
res are also on.
- Tracer spring action indicator: If this is lit, it means the tracer spring action
system is enabled. If it is off, then the system is disabled.
- MODE switch: This turns the illuminated cutter and tracer height adjustment
system on and off.
- LED strip: Lights indicating the vertical force applied by the tools when cutting
dimple keys. NOTE: When optimal force is achieved, the machine emits a sound.
- Arrows: These indicate the direction in which the cutter-tracer height regulator
should be turned for adjustment. The cutter-tracer height is properly adjusted when the
two blue lights next to their corresponding arrows light up at the same time.
2. Clamp carriage assembly: for moving the clamp on the X and Y axes via precision
guide rails.
3. Carriage assembly control lever: for moving the carriage assembly so that various
points of the key are positioned next to the cutter.
4. Head: for moving the cutter and tracer vertically (Z axis).
5. Head control lever: for moving the head downwards when cutting a key.
- By turning it clockwise, it can also be used to lock the head at the desired height
(necessary for cutting sidewinder keys).
The operator MUST hold the carriage assembly control lever (3) and the
head control lever (5) when cutting keys.
6. Carriage spring action handle: for enabling and disabling the carriage assembly
spring action system on the X axis. Very useful when cutting sidewinder keys.
7. Carriage lock handle: for locking the carriage on the X axis. Very useful when cut-
ting a row of dimples on the same X axis on dimple keys.
- To enable this lock, the carriage assembly spring action handle also needs to be
enabled.
8. Clamp:
- Rotating.
- With two usable sides.
- With interchangeable grips.
9. Clamp handle: For opening and closing the clamps.
10. Clamp rotation locking handle: for locking clamp rotation at the required angle.
11. Tool chuck: This makes inserting tools (cutter and tracer) quick, convenient and
precise.
12. Cutter: Made from high-speed steel (HSS). Cutters are available in different sha-
pes and sizes based on the geometry of the dimples or grooves on the key being copied.
13. Cutter lock button: for manually locking cutter rotation when switching cutters.
14. Tracer: specifically designed to read the key coding. The tracer to be used should
be the one corresponding to the cutter required for each specific copy.
15. Cutter-tracer height regulator: for moving the tracer position vertically to adjust the
height between cutter and tracer.
16. Tracer spring action handle: for enabling and disabling the tracer spring action
system.
- Enable the tracer spring action system when cutting dimple keys.
- Disable the tracer spring action system when cutting sidewinder keys.
17. Tubular support lever: Pulling this lever 90º provides support for the hand operating
the carriage assembly control lever when cutting tubular keys.
18. Tool holder: An accessory that lets you store various cutter and tracer sets in a tidy
fashion.
19. Swarf protective shield: This prevents the swarf created when cutting keys from
being ejected outwards from the machine towards the operator.
20. Motor housing: This protects the motion transmission system between the motor
and the rotating head of the cutter.
21. Lights: This illuminates the work area using LED technology.
22. Speed selector: For selecting the cutter rotation speed.
- Speed 1 (low) for HSS cutters.
- Speed 2 (high) for TOUGHENED METAL cutters.
23. Plug: For connection to a power supply
The plug is fitted with a 6A/220V fuse that protects against any potential
faults in the electrical circuit.
24. Master switch: for switching the machine on or off.

4.7 COMPONENTS AND FUNCTIONAL PARTS

4.7.1 CHANGING THE CUTTER AND TRACER POINT
To release the cutter, you have to press the cutter blocking button and at the same time
rotate the tool-holder by hand.
After removing the cutter to be replaced, insert the new cutter and secure it in the
tool-holder, making sure that its end butts up against the inside of the tool-holder.
The tracer point is replaced in the same way as the cutter. The only difference to bear in
mind is that the rotation of the tracer point is always blocked internally.
4.7.2 BLOCKING THE SLIDE AT THE END OF THE "Y" AXIS TRAVEL
In order to prevent the slide from moving in the "Y" direction, whilst the key cutting
machine is holding the keys in the clamp, the slide has been equipped with momentary
blocking in that direction.
To active this blocking, just move the slide as far as it will go in the direction towards
to the key cutting machine.
To deactivate the blocking, just move the slide forward, exercising a little force.
4.7.3 CLAMP
The features of the clamp on the CAPRI key cutting machine are superior to those of any
normal machine on the market, as it has two separate clamping faces. In addition, the
clamps can be blocked in any rotation position between 45º 0º -45º.

5.- OPERATION AND FUNCTIONS

5.1 KEY CUTTING PROCESS
• Switch on the machine using the main switch located on the back right-hand side
of the machine.
• To improve visibility in the work area, activate the lighting by turning on the switch
located on the keypad-display.
• With the help of the table provided in this manual, select the cutter and tracer
point necessary to cut the key.
• Change the cutter and tracer point.
• Momentarily block the slide at the end of the "Y" axis travel.
• Secure the original key in the left side of the clamp, and the key to be cut in the
right side. When securing the keys, bear in mind the following details:
- KEY STOP. It may be a key which is stopped from being inserted further by its
shoulders (Fig. 4.A), or a key stopped by its tip (Fig. 4.B).
- ADAPTOR. For some very specific types of key, it may be necessary to use an
adaptor.
- ANGLE CUT. Some keys have angle cut dimples, for which it is necessary to
rotate the clamp.
• Carry out the vertical adjustment of the tracer point.
• Activate the systems which simplify the cutting work:
TRACER POINT: Activate or deactivate the tracer point spring mechanism,
depending on the type of key being cut.
SLIDE: Based on the model of key, it may be a good idea to activate the slide
spring mechanism, or block the slide in the "X" direction.
SUPPORT: Depending on the type of key, it may be a good idea to use the support
lever for tubular keys.
• Start rotating the cutter, having first selected one of the two speeds available.
• Proceed to cut the key. If it is a dimple key, use the help of the cutting force
control system.

5.2 KEY CUTTING

5.2.1 KA-2, KA-3 AND KA-4 KEYS.
• Different pairs of cutters and tracer points are used depending on the key to be cut.
See table.
• The key is secured in the clamp when its shoulders stop it from being inserted any
further.
• Depending on the model of key to be cut, it is necessary to rotate the clamps based
on the angle required. See table.
• It is necessary to activate the tracer point spring mechanism.
• Use the cutting force control system to increase cutting precision.
• NOTE: The dimples cut on the KA-3 key must always be on the lowest part of the
clamp.
• NOTE: The dimples cut on the KA-2 key must always be on the highest part of the
clamp.
See Fig. 5
5.2.2 KE-1 KEY.
• Use cutter-tracer point pair: F-1 / P-1.
• The key is secured in the clamp when its shoulders stop it from being inserted any
further, but in this case it is inserted from the back.
• It is necessary to position the clamps at an angle of 5º.
• It is necessary to activate the tracer point spring mechanism.
• Use the cutting force control system to increase cutting precision.
• NOTE: The dimples cut on the KE-1 key must always be on the highest part of the
clamp.
• NOTE: You have to use the relevant adaptor to cut the lateral dimples.
See Fig. 6
5.2.3 SEA-1 KEY.
• Use cutter-tracer point pair: F-3 / P-3.
• The key is secured in the clamp when its shoulders stop it from being inserted any
further.
• It is necessary to block the tracer point (deactivate the spring mechanism).
• NOTE: After vertically adjusting the tracer point, you need to slightly lower the
tracer point, by turning the adjustment wheel 5 points to the right. Then you have to
