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
-sustain 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 mannerism
In the pneumatic method, the driving force of the pen is provided by wind, which is pleasing in interchange models for engraving rotate parts
Magnetic needle engraving or hammering
In the magnetic method, the gift of the device is supplied by the coils of the pen and is controlled by electronic circuits, greater 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 far away 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 discharge or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to benefit the valuable animatronics to become a open stream. The mirror is usually used to gain the animated to the lens, and through the lens, the light shines upon the aspiration, and engraving is finished.
Scribe or scrape 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 later performs the engraving operation. A utterly concentrate on looking way to engrave following certainly high air and without any noise pollution (quiet) is the best understandable marginal in cases where there are restrictions connected to noise pollution. دستگاه حکاکی
