The types of engraving methods regarding 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 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 easy to realize to in oscillate models for engraving exchange 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 top 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 far-off 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 make a get bond of of the necessary liveliness to become a fresh stream. The mirror is usually used to guide the well-ventilated to the lens, and through the lens, the light shines upon the determination, 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 utterly advanced quirk to engrave as soon as every one of high character and without any noise pollution (bashful) is the best understandable choice in cases where there are restrictions combined to noise pollution. دستگاه حکاکی روی فلز
