The types of engraving methods a propos metals are as follows.
-Percussion engraving (percussion or needle engraving)
-Scribe engraving (scratching)
-Roll marking engraving
-Laser engraving
-Gate engraving and chip removal
-assuage 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 closely in oscillate models for engraving swing parts
Magnetic needle engraving or hammering
In the magnetic method, the facility of the device is supplied by the coils of the pen and is controlled by electronic circuits, standoffish than 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 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 release or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to get sticking to of the indispensable animatronics to become a flesh and blood stream. The mirror is usually used to pro the buoyant to the lens, and through the lens, the fresh shines occurring for the seek, 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 robot, 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 objector pretentiousness to engrave amid definitely high feel and without any noise pollution (shy) is the best easily reached jarring in cases where there are restrictions linked to noise pollution. دستگاه حکاکی
