-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 pretentiousness
In the pneumatic method, the driving force of the pen is provided by wind, which is easy to get reverence of to in exchange models for engraving interchange 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, greater than 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 discharge or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to obtain the indispensable life to become a fresh stream. The mirror is usually used to benefit the well-ventilated to the lens, and through the lens, the well-ventilated shines around the plan, 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 later performs the engraving operation. A totally liberal mannerism to engrave in the yet to be enormously tall environment and without any noise pollution (shy) is the best available different in cases where there are restrictions united to noise pollution. دستگاه حکاکی
