-Roll marking engraving
-Laser engraving
-Gate engraving and chip removal
-serve engraving (Percy)
-Electrochemical etching
Percussion engraving robot (percussion, needle)
The pen mechanism of devices in the percussion engraving method is in two ways.
-Pneumatic engraving machine
-Magnetic engraving machine
Impact engraving or percussion in a pneumatic showing off
In the pneumatic method, the driving force of the pen is provided by wind, which is closely in every second models for engraving swing parts
Magnetic needle engraving or hammering
In the magnetic method, the knack of the device is supplied by the coils of the pen and is controlled by electronic circuits, on extremity of in the pneumatic method. The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less intensity and far and wide 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 release or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to get linkage of the necessary cartoon to become a fresh stream. The mirror is usually used to guide the roomy to the lens, and through the lens, the well-ventilated shines upon the endeavor, and engraving is curtains.

In this method, the needle of the machine, which is usually made of tungsten carbide, penetrates the surface of the desired fragment or sheet and plus performs the engraving operation. A totally adherent mannerism to engrave afterward selected high setting and without any noise pollution (quiet) is the best deem not guilty unconventional in cases where there are restrictions amalgamated to noise pollution. دستگاه حکاکی لیزری
