Visible and near infrared lasers such as nd yag see figure 1 can cause retinal damage while far infrared lasers such as co 2 see figure 2 and ultraviolet lasers can cause corneal damage.
Dangers of laser sheet metal cutter.
At the same time the thermal cutting method makes material melt resulting in emitted gases and dangerous fumes.
Kern s co2 and fiber laser systems can be equipped with innovative metal cutting technology.
Those using machine very low risk.
Engage with cutting speed and.
Table 1 lists some reference values.
The condition usually only lasts a single day according to the occupational safety and health administration with workers most susceptible after several days away from the work environment.
Ensure ventilation is on an advance of using machine.
Abs emits cyanide gas and tends to melt abs does not cut well in a laser cutter.
The laser beam itself is the first safety concern.
It also does not engrave well again tends to melt.
This means that should the laser beam be reflected by the flat sheet it can be transmitted back through the beam delivery optics and into the laser itself potentially causing significant damage.
It can be dangerous to both the eyes and the skin.
Most laser cutting machines use a laser beam aligned normal to a flat sheet of material.
Laser cutters will generate fumes vapors particulates and metal fumes from substrate that can be highly toxic plastics and other combustible materials.
Burns to skin eyes.
All laser cutter systems must be equipped with a fume exhaust system and filtration system that meets manufacturer specifications.
Injuries occur when a person is overexposed by viewing the laser beam directly or by a specular or diffusely reflected beam.
Polycarbonate is a poor choice for laser cutting.
Ensure correct cutting speeds and power for material being cut.
Generally for any kind of hot cutting technology drill a small hole in the sheet metal is necessary except a few cases can start from the edge of the sheet metal.
Ensure guard is engaged and not opened during preparation.
Previously it was punched out a hole with the punch mold in the laser stamping machine then the laser began to cut through the hole.
Dangers and safety precautions.
The automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal.
Regarding the relationship between the range of the heat affected zone and the thickness of the basic material.
Aluminium is more reflective than c mn steel or stainless steel and has the potential to cause damage to the laser itself.
It tends to melt rather than vaporize and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid.
Laser flame cutting and laser melting cutting will cause material variation in the edge area of the cut material.
Dangerous fumes one of the advantages of laser cutting is its suitability for cutting different materials.
