According to statistics, in recent years, the proportion of short circuits caused by floating objects in the line has reached 25% of all external damages, and the length of the 10-kV line of the Dongguan distribution network accounts for 60% of the overhead lines of the entire Dongguan power grid. "

The nozzle is used to spray auxiliary gas to the cutting area. Generally, a coaxial (air flow and optical axis coaxial line) nozzle is used on a laser cutting machine. About it, the universe is big and it will affect the cutting quality if it is not done well.1. The shape of the nozzleThere are many

Laser tube, full name: glass sealed-off CO2 laser. Because this laser is encapsulated by a glass tube, it is commonly called a laser tube.Working principle: High-voltage discharge excites high-concentration CO2 gas to produce a laser with a wavelength of 10.6um.It is mainly composed of hard glass, r

Precautions for the use of laser tubeAnalysis of years of experience in laser production of micro-engraving laser:1. When using, please connect the cooling water first, adopt the principle of low inlet and high output, adjust the position of the outlet pipe to ensure that the cooling water is full o

Laser engraving machine processing wood has a special way of expression, that is, the laser of the laser engraving machine can be "inkless engraving" on wood, which is a kind of thermal processing, and the melting point of wood is relatively low, and it is easy to stay Black traces are lowered, so
