There is another factor that takes into play such as the wavelength of the laser.
Lasers that cut through metal.
If the cutting speed is too fast missed cuts will inevitably occur which will cause not cut through problem.
A metal cutting laser has to use at least 300 w which will run you up to at least 10 000.
However most industrial lasers cannot cut through the greater metal thickness that plasma can.
Sheet metal cutting requires a power density of 10 6 watts in 2 source.
It has an engraving area of 12 x 8 inches 300 x 200 mm a cutting speed of 0 1 38 inches per second 0 35 mm per second and a minimum shaping character of 0 04 x 0 04 inches 1 mm x 1 mm.
However comparing this to the fiber laser cutting process the latter is more advantageous when it comes to cutting metal a gas laser cutting machine can generally cut quicker than a fiber laser but this only applies to thick metals.
For thin metals fiber lasers are quicker.
The cutting speed of the laser cutting machine is too fast.
The two most common types of laser cutting machines are fiber laser and co 2.
If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing.
The auxiliary gas pressure of the equipment is not enough.
A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins.
Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting.
Furthermore when using a gas laser there is a much higher risk of damaging the metals that you are working with.
This co2 laser engraver s fan ensures to extract fumes and smoke.
Co 2 lasers use an electromagnetically stimulated gas typically a mixture.
Advanced metal cutting features in the kcam laser software allows for complete control of the metal cutting process.
The nozzle air pressure can be set independently for the laser dwell normal laser cutting and jog between parts.

You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface.
When the air pressure is not reached the.
Fiber laser has 1064nm whi.
In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist.
Fiber lasers vs co 2.
However it won t cut through metal.
Metal laser cutting does not rely on pure laser power in cutting process.
The auxiliary gas is used to help blow off the residue during cutting.
1in 2 645mm 2 a 100 watt laser can achieve a power density of 1550 watts mm 2 in a spot size that is 0 6452mm 2 a spot size that is 0 6452mm 2 has a diameter of of 28mm or 280 micron using area pi d 2 2 280 micron.
