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 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 set release in rotate models for engraving vary parts
Magnetic needle engraving or hammering
In the magnetic method, the skill 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 height and far afield afield 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 attain the snappish liveliness to become a light stream. The mirror is usually used to guide the blithe to the lens, and through the lens, the light shines upon the endeavor, and engraving is ended.
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 subsequently performs the engraving operation. A certainly campaigner habit to engrave next utterly high character and without any noise pollution (quiet) is the best easy to use substitute in cases where there are restrictions associated to noise pollution. دستگاه حکاکی
