Electric installation advice

This material is «class 1». The mains plug MUST always be connected to a neutral
socket and comply with the regulations in force in the country of installation. If you
do not have a plug of this type, have one installed by an approved electrician. Under
no circumstances should you depart from this instruction.

In order to avoid outside interference, the user is advised to carry out the following points.

• Plug the Gravograph machine into a mains line, avoiding having several machines on the same line (several plugs on the
same line or using a multi-plug).

Exception : If other things are connected to the machine (such as a computer or an ISIS console

linked to an IS table), the machines should be connected to the same mains line.

• Avoid using the same line to supply inductive or capacitive machines as well as the Gravograph machine (motors,
electrosluices, chargers...).

• Avoid using a manual or automatic commutator on the same mains line as the Gravograph machine (relay, temporiser,
programmer, automatic circuit interrupter, automatic interrupter...).

• Check that machines surrounding your Gravograph machine are in conformity to the norms of radioelectric perturbation
emissions (consult the technical leaflet of each machine). If they are not in conformity, place them as far away as possible
from the Gravograph machine.

• Only use Gravograph accessories (Gravograph relay box, etc ...).

Putting the cutter into the spindle

This plate will be engraved using a conical tool (or conical cutter) made of high speed steel with a 4.36 mm diameter and
a 0.50 tip.

12. Lower the spindle until the depth regulating nose touches the material to be engraved

(diagram 31).

To lower press

13. Open the belt housing of the tool-holder (diagram 32).

14. Screw knob of cutter onto the spindle (diagram 32).

The spindle knob should be tightened anti-clockwise (knob with left-hand thread).

The tool is very sharp and to avoid any risks of getting cut, you are advised to use some
kind of protection (gloves) to handle it.

First contact

15. Insert the cutter into the button until it is touching slightly (carbide cutters are not very shock

resistant) the engraving material (diagram 33). To facilitate the insertion of the cutter, slightly

unscrew the screw located on the spindle knob (diagram 34).

Remember to program 0.5 to 1 mm depth to compensate possible flatness faults of the plate.

16. Tighten the screw of the cutter button to lock it into place.

For greater convenience, we advise that you have as many cutter knobs as you have
cutters, so you can leave them together and keep the settings for possible jobs to be
carried out in the same conditions in the future (same thickness of materials).
For this, you will need to request "the machine configuration save with ZREF" (see
"Saving the machine configuration" paragraph of chapter "Basic techniques" in the
user manual "CN97 Program").

Adjusting the tool depth

18. Turn the index finger a few notches to the right to obtain the desired engraving depth (one notch

= 0.025 mm) (diagram 35).

Refer to the table opposite for the number of marks to move the index finger depending on the desired depth and the material
used.

19. Tighten the index finger in order to maintain the scaled knob in this position.

20. Close the belt housing of the tool-holder.

To avoid any risks of getting burnt, the protective belt housing of the tool-holder must
be always closed, except when carrying out adjustments.

Starting to engrave

This sign shown on the spindle of the machine shows the danger caused by the
rotating spindle during engraving (risks of getting burnt or cut).

To avoid any risks of getting burnt, the belt housing of the tool-holder must be always
closed except for when adjusting the tool-holder and changing the spindle belt.

For your own personal safety and to avoid any risks of being crushed by the machine
during engraving, do not stand near the tools or lean over the spindle holder (the travel
area of the tool is 305 x 210mm).

Always wear protective glasses againts chip ejection.

Before starting the engraving, ensure that the spindle travel area is completely clear.

Ensure that no one is in the travelling area of the moving parts of the machine and that
no object will obstruct the travelling of the moving parts.

22. Press START (Engraving Start)

The tool holder moves over to the first point on the engraving and starts to engrave.

To stop engraving (if there is a problem), press PAUSE

The machine will pause.

To continue engraving, press START (Engraving Start)

General maintenance

Before carrying out any maintenance, unplug the mains supply cable.

No internal part of the Gravograph machine requires user intervention : general maintenance is limited to external cleaning.
If necessary, the user can change the belt.

If you wish to have the inside of your machine cleaned, contact a Gravograph technician.

The mains cable should always be replaced if it is damaged in any way : flattened,
nicked, cracked etc..., or if there are bare wires.

Changing the belt

You will find a spare belt in the machine tool box.

1. Open the protective housing of the tool-holder and take it out by lifting it upwards (diagram 36).

2. Loosen the 2 screws fixing the belt housing and the axis of the protective housing of the tool-

holder, then take of the belt housing (pict 36).

3. Pull the belt off with one hand, and turn the motor pulley with the other (pict 37).

4. Put the belt in the spindle pulley groove.

5. Put the belt into the pulley groove opening with one hand and turn the pulley with the other

(pict 38).

6. Replace the plastic casing and tighten the two screws fixing the case.

7. Screw the axis of the tool-holder housing and replace it.

8. Close the tool-holder housing.

To avoid any risks of getting burnt, the protective belt housing of the tool-holder must
be always closed, except when carrying out adjustments.

Adjusting the machine

After it has been used for some while the reference point of the machine can alter slightly (the centre of the engraving area
of the machine is slightly out of line with the clamping system, the Z position at the mechanical stop is above or below its
normal position).
The IS400 machine has a very simple adjustment system which can be carried out by the user (which enables the machine
to be adjusted without having to return it to the distributor).
If you notice that it is out of line in relation to your engraving measurements, adjust the machine.

To adjust the machine

1. Switch on the IS400 machine.
