Micro-percussion
technology |
 |
Micro-percussion marking
deforms the material using a vibrating tool.
This technology
does not provoke stress onto the material regardless of
the thickness of the marked part and no material is removed, like in:
|

Pneumatic micro-percussion |
A
continuous stream of compressed air is directed to the piston
at the top of the point and pushes it downwards before being evacuated through holes on the side.
A
spring pushes the piston and the point upwards again. It is possible to obtain very high
vibration frequencies, between 200 and 300 Hz using relatively
high levels of energy without any risk of overheating.
The
actual design of the stylus, whose point and head vibrate
between
an air cushion and a spring makes it possible to mark flat,
concave or convex surfaces without modifying the distance of
the part
to be marked.
The
amplitude of the tool can indeed reach .25” (6 mm). |

Electromagnetic micro-percussion |
The
main advantages of the electromagnetic stylus in comparison with the pneumatic technology are:
- - A
reduced level of noise
- - Increased depth accuracy
- - A
greater amplitude making for optimal quality markings
on curved surfaces
- - Mono-energy operating
Under
the action of the electromagnetic field, the core pushes the
stylus downwards and a spring pushes it back to its start position.
The frequencies obtained are lower, around 80 Hz, but the amplitudes
are greater however.
The
impact force and therefore the width of a character's line
and the marking depth will depend on the power of the
electro-magnet. Only one electromagnetic stylus model
is available, the EM11B stylus, which can cover a wider range of
impact forces than pneumatic stylus. |
