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