All Laser Cutters want two additional products which move atmosphere: blower which removes air flow / extracts smoke from machine and Air Compressor For Tire Production Equipment atmosphere compressor as a source for compressed air flow for so called air flow assist.
Why and How
Laser cuts by warmth, very high warmth focused in tight beam. Side products 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 surroundings to burn nonetheless it will also die if you blow too hard, think about a candle in the wind. This is essentialy what air flow assist can be for: compressed atmosphere is extruded directly at the laser mind in a very restricted stream and is directed at where laser touches material.
Pressure and level of air
Pressure of air flow is key variable for air aid efficienty, in our shop we discovered that optimal worth is between 2 and 3.5 bar (31-50psi).
To accomplish required pressure compressor must push certain volume of air through air assist opening, precise 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 generally direction via huge holes.
When choosing compressor you should consider if it will be able to constantly provide desired pressure and volume of air. Little airbrush compressors small compressors boast impressive pressure figures but actually poor flow rates enough only for airbrush pistols. Also if small compressor can push enough air it will likely overheat in short while.
