The types of engraving methods upon metals are as follows.
-Percussion engraving (percussion or needle engraving)
-Scribe engraving (scratching)
-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 robot
-Magnetic engraving robot
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 handy in swing models for engraving choice parts
Magnetic needle engraving or hammering
In the magnetic method, the power of the device is supplied by the coils of the pen and is controlled by electronic circuits, on elevation of in the pneumatic method. The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less extremity and in the estrange 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 get sticking to of the valuable energy to become a spacious stream. The mirror is usually used to gain the roomy to the lens, and through the lens, the fresh shines upon the intend, and engraving is done.
Scribe or scuff engraving
It is one of the newest engraving methods in the world. 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 subsequently performs the engraving operation. A intensely modern mannerism to engrave when utterly high air and without any noise pollution (bashful) is the best to hand different in cases where there are restrictions joined to noise pollution. دستگاه حکاکی روی فلز
