All Laser Cutters want two additional gadgets which move air: blower which removes air flow / extracts smoke from machine and surroundings compressor as a source for compressed air for so called surroundings assist.
Why and How
Laser cuts by temperature, very high warmth focused in tight beam. Side products of high temperature are smoke and fire, both are not welcomed addition, smoke disperses laser beam reducint it’s efficienty and fire causes charring of materials / edges and can even escape control leading to serious emergency.
Fire needs surroundings to burn nonetheless it can also die in the event that you blow too hard, think about a candle in the wind. This is essentialy what surroundings assist is usually for: compressed air flow is extruded directly at the laser mind in a very limited stream and is fond of the place where laser touches material.
Pressure and level of air
Pressure of surroundings is essential variable for air support efficienty, in our shop we discovered 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 air assist opening, specific 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 https://www.ever-power.net/?s=laser+cutting+air+compressor&post_type=product 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 little compressors boast amazing pressure figures but really poor flow rates enough only for airbrush pistols. Actually if small compressor can push enough air it’ll likely overheat in short while.
