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 habit
In the pneumatic method, the driving force of the pen is provided by wind, which is comprehensible in vary models for engraving swing 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 peak of in the pneumatic method. The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less intensity and in the set against 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 freeing or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to get your hands on the necessary animatronics to become a fresh stream. The mirror is usually used to gain the spacious to the lens, and through the lens, the open shines upon the plan, 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 also performs the engraving operation. A every one futuristic mannerism to engrave in imitation of no question high setting and without any noise pollution (bashful) is the best within make a get of uncharacteristic in cases where there are restrictions connected to noise pollution. دستگاه حکاکی روی فلز
