All Laser Cutters need two additional devices which move air flow: blower which removes air / extracts smoke from machine and air flow compressor as a source for compressed surroundings for so called air flow assist.
Laser cuts by warmth, very high warmth focused in tight beam. Side items of high temperature are smoke and fire, both are not welcomed addition, smoke disperses laser 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. This is essentialy what air flow assist is certainly for: compressed surroundings is extruded straight at the laser mind in a very tight stream and is directed at where laser touches material.
Pressure of atmosphere is key adjustable for air support efficienty, inside our shop we discovered that optimal value is between 2 and 3.5 bar (31-50psi).
To accomplish Laser Cutting Air Compressor required pressure compressor must push certain volume of air through air flow assist opening, precise volume depends upon size of the starting and desired pressure. Top quality laser beam cutter heads have small and finely tuned openings while cheaper chinese cutters just blow in general direction via huge holes.
