2/ POSITIONING AND CLAMPING OF THE PARTS

The part is submitted to high forces, it is necessary to immobilize it or to fix it in order to
reach a good alignment of the characters during the marking process and a regular marking
depth. Depending on the type of parts and the working conditions, the clamping system
can vary from the simple manual fastening of the part against an angle iron (bracket) to the
mechanical, magnetic or pneumatic fastening.

3/ ADJUSTMENT OF THE MACHINE

In order to obtain a good marking quality, the following parameters have to be taken into
account:
A) ADJUSTMENT OF THE DISTANCE PIN/PART
It is important to adjust the distance between the pin and the part to obtain a good marking
quality.
This distance has to be minimized not to damage the pin on first impact.
Minimum distance: 0,5 mm
Optimum reached from 0,5 to 1 mm
The stroke of the pin is mechanically limited to 4 mm.
B/ PRESSURE REGULATION
Marking pressure is ruled by the manometer on the machine.
Maximum pressure is 3.5 bars
Minimum pressure is 0.5 bar
Don't raise the pressure if not needed. It may damage faster the pin. When pressure is
important, lower the pin/part distance to the minimum.
4/ MATERIAL AND PARTS SHAPE
The marking quality highly depends on the part to be marked.
A smooth and flat surface is much easier to mark than a rough and irregular surface.
Preliminary tests should be conducted if the part to be marked is new.
It is generally necessary to adapt the marking force (pressure) to the height of the
character. The smaller the character is, the lower the scratching pressure has to be to
obtain a good legibility.
