Lasers That Cut Through Metal

However it won t cut through metal.

Lasers that cut through metal.

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. There is another factor that takes into play such as the wavelength of the laser. If the cutting speed is too fast missed cuts will inevitably occur which will cause not cut through problem. The two most common types of laser cutting machines are fiber laser and co 2.

A metal cutting laser has to use at least 300 w which will run you up to at least 10 000. 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. Furthermore when using a gas laser there is a much higher risk of damaging the metals that you are working with. You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface.

Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Fiber lasers vs co 2. Laser cutting for metals has the advantages over plasma cutting of being more precise and using less energy when cutting sheet metal. Somehow the shorter the laser wavelength the finer the cutting.

Sheet metal cutting requires a power density of 10 6 watts in 2 source. The auxiliary gas pressure of the equipment is not enough. Co 2 lasers use an electromagnetically stimulated gas typically a mixture. However most industrial lasers cannot cut through the greater metal thickness that plasma can.

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. Metal laser cutting does not rely on pure laser power in cutting process. The nozzle air pressure can be set independently for the laser dwell normal laser cutting and jog between parts.

When the air pressure is not reached the. 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.

A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. For thin metals fiber lasers are quicker. Fiber laser has 1064nm whi. The cutting speed of the laser cutting machine is too fast.
