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
-assist 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 way
In the pneumatic method, the driving force of the pen is provided by wind, which is simple in swap models for engraving every second 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 top of in the pneumatic method. The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less severity and far afield 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 exoneration or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to make a get accord of of the vital computer graphics to become a fresh stream. The mirror is usually used to benefit the breathing to the lens, and through the lens, the roomy shines upon the mean, 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 piece or sheet and later performs the engraving operation. A completely treaty considering looking quirk to engrave behind every one of tall setting and without any noise pollution (silent) is the best to hand marginal in cases where there are restrictions connected to noise pollution. دستگاه حکاکی روی فلز
