All Laser Cutters need two additional devices which move air: blower which removes atmosphere / extracts smoke from machine and atmosphere compressor as a source for compressed air for so called atmosphere assist.
Why and How
Laser cuts by warmth, very high warmth focused in tight beam. Side items of high temperature are smoke and fire, both aren’t welcomed addition, smoke disperses laser reducint it’s efficienty and fire causes charring of material / edges and can even get out of control leading to serious emergency.
Fire needs atmosphere to burn but it will also die if you blow too hard, think of a candle in the wind. That is essentialy what air flow Air Compressor For Tire Production Equipment assist can be for: compressed air flow is extruded straight at the laser mind in a very tight stream and is fond of the place where laser touches material.
Pressure and level of air
Pressure of air is essential variable for air help efficienty, in our shop we found out that optimal worth is between 2 and 3.5 bar (31-50psi).
To attain required pressure compressor needs to push certain volume of air through atmosphere assist opening, specific volume depends on size of the starting and desired pressure. High quality laser beam cutter heads have little and finely tuned openings while cheaper chinese cutters just blow in general direction via large holes.
When choosing compressor you need to consider if it can constantly provide desired pressure and level of air. Small airbrush compressors small compressors boast impressive pressure figures but really poor flow rates adequate only for airbrush pistols. Also if small compressor would be able to push enough air it’ll likely overheat in short while.
