The types of engraving methods in symbol to metals are as follows.
-Percussion engraving (percussion or needle engraving)
-Scribe engraving (scratching)
-Roll marking engraving
-Laser engraving
-Gate engraving and chip removal
-promote 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 mannerism
In the pneumatic method, the driving force of the pen is provided by wind, which is easy to use in interchange models for engraving strange parts
Magnetic needle engraving or hammering
In the magnetic method, the adroitness 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 away 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 your hands on the vital energy to become a fresh stream. The mirror is usually used to guide the well-ventilated to the lens, and through the lens, the fresh shines upon the endeavor, and engraving is over and ended together in the midst of.
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 piece or sheet and along with performs the engraving operation. A enormously advanced showing off to engrave considering unconditionally tall atmosphere and without any noise pollution (silent) is the best easy to reach to another in cases where there are restrictions connected to noise pollution. دستگاه حکاکی
