Lasers That Cut Through Metal

The two most common types of laser cutting machines are fiber laser and co 2.

Lasers that cut through metal.

Co 2 lasers use an electromagnetically stimulated gas typically a mixture. This co2 laser engraver s fan ensures to extract fumes and smoke. You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface. In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist.

The auxiliary gas pressure of the equipment is not enough. A metal cutting laser has to use at least 300 w which will run you up to at least 10 000. However it won t cut through metal. Laser cutting for metals has the advantages over plasma cutting of being more precise and using less energy when cutting sheet metal.

Fiber laser has 1064nm whi. Fiber lasers vs co 2. However most industrial lasers cannot cut through the greater metal thickness that plasma can. For thin metals fiber lasers are quicker.

The nozzle air pressure can be set independently for the laser dwell normal laser cutting and jog between parts. If the cutting speed is too fast missed cuts will inevitably occur which will cause not cut through problem. 1 16 of over 2 000 results for laser metal cutting ortur laser master 2 laser engraver cnc laser engraving cutting machine diy laser marking for metal with 32 bit motherboard lasergrbl lightburn 400x430mm large engraving area 20w 3 8 out of 5 stars 14. 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.

If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing. The cutting speed of the laser cutting machine is too fast. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Advanced metal cutting features in the kcam laser software allows for complete control of the metal cutting process.

When the air pressure is not reached the. 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. Sheet metal cutting requires a power density of 10 6 watts in 2 source. There is another factor that takes into play such as the wavelength of the laser.

A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. Metal laser cutting does not rely on pure laser power in cutting process. Furthermore when using a gas laser there is a much higher risk of damaging the metals that you are working with. 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.
