Lasers That Cut Through Metal

The auxiliary gas is used to help blow off the residue during cutting.

Lasers that cut through metal. Somehow the shorter the laser wavelength the finer the cutting. 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. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.

The two most common types of laser cutting machines are fiber laser and co 2. The nozzle air pressure can be set independently for the laser dwell normal laser cutting and jog between parts. Co 2 lasers use an electromagnetically stimulated gas typically a mixture. The cutting speed of the laser cutting machine is too fast.

The auxiliary gas pressure of the equipment is not enough. When the air pressure is not reached the. However it won t cut through metal. 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.

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. If the cutting speed is too fast missed cuts will inevitably occur which will cause not cut through problem. For thin metals fiber lasers are quicker.

Advanced metal cutting features in the kcam laser software allows for complete control of the metal cutting process. Sheet metal cutting requires a power density of 10 6 watts in 2 source. You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface. 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.

In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist. If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing. However most industrial lasers cannot cut through the greater metal thickness that plasma can. A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins.

A metal cutting laser has to use at least 300 w which will run you up to at least 10 000. Fiber laser has 1064nm whi. There is another factor that takes into play such as the wavelength of the laser. Fiber lasers vs co 2.
