Lasers That Can Cut Through Metal

Somehow the shorter the laser wavelength the finer the cutting.

Lasers that can cut through metal.

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. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2. 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. Laser cutting for metals has the advantages over plasma cutting of being more precise and using less energy when cutting sheet metal.

A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. The above six points are the main reasons why the fiber laser cutting machine cannot cut through. The nozzle air pressure can be set independently for the laser dwell normal laser cutting and jog between parts. Metals such as stainless steel and aluminum can be cut with a laser when compressed gas technology is used.

You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface. 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. There is another factor that takes into play such as the wavelength of the laser. However most industrial lasers cannot cut through the greater metal thickness that plasma can.

A metal cutting laser has to use at least 300 w which will run you up to at least 10 000. The majority of users can pay more attention to these problems during daily use. Advanced metal cutting features in the kcam laser software allows for complete control of the metal cutting process. In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist.

Newer laser machines operating at higher power 6000 watts as contrasted with early laser cutting machines 1500. 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. Instead the 40 watt laser is best used on.

Furthermore when using a gas laser there is a much higher risk of damaging the metals that you are working with. For thin metals fiber lasers are quicker. Metal laser cutting does not rely on pure laser power in cutting process. 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.

Most lasers capable of cutting through even steel plates are high power capacity co2 lasers.
