Lasers That Can Cut Through Metal

In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist.

Lasers that can cut through metal. When faced with a problem it needs to be solved step by step so as to obtain better results in daily processing. Metals such as stainless steel and aluminum can be cut with a laser when compressed gas technology is used. Nanoseconds which causes. Somehow the shorter the laser wavelength the finer the cutting.

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. A metal cutting laser has to use at least 300 w which will run you up to at least 10 000. Instead the 40 watt laser is best used on.

A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. Most lasers capable of cutting through even steel plates are high power capacity co2 lasers. This is due to fusion cutting operating with lasers either in continuous waves or with significantly longer pulses than ablative cutting micro or milliseconds vs. Laser cutting for metals has the advantages over plasma cutting of being more precise and using less energy when cutting sheet metal.

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. Fiber laser has 1064nm whi. First ablative laser cutting can be used to make partial cuts in a material whereas laser fusion cutting can only be used to cut all the way through it.

For thin metals fiber lasers are quicker. However most industrial lasers cannot cut through the greater metal thickness that plasma can. The above six points are the main reasons why the fiber laser cutting machine cannot cut through. Sheet metal cutting requires a power density of 10 6 watts in 2 source.

Even though digilab s lc40 is a co2 laser cutting metal is not one of the features of the laser. 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. Newer laser machines operating at higher power 6000 watts as contrasted with early laser cutting machines 1500. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.

There is another factor that takes into play such as the wavelength of the laser.
