-Pneumatic engraving robot
-Magnetic engraving robot
Impact engraving or percussion in a pneumatic habit
In the pneumatic method, the driving force of the pen is provided by wind, which is realizable in every second models for engraving exchange parts
Magnetic needle engraving or hammering
In the magnetic method, the take steps of the device is supplied by the coils of the pen and is controlled by electronic circuits, future than in the pneumatic method. The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less intensity and in the disaffect less noise pollution than the pneumatic system.
Laser engraving
In the laser method, the ray is produced by stimulating the laser generating material by electric discharge or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to make a attainment of the indispensable cartoon to become a fresh stream. The mirror is usually used to pro the blithe to the lens, and through the lens, the fresh shines upon the seek, and engraving is the call off.
