Mar 06 2015 final installment in a series of three articles comparing metal cutting lasers in two previous articles we examined the differences in electrical costs and resonator operating costs between the various types of metal fabrication lasers.
Percentage laser cutting sheet metal.
Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.
Draw a contour of a part you want in a vector drawing software.
Laser cutting does not cause any deformation mainly because the workpiece needs little heat input and most of it can be cut.
In this scenario the precision plasma cutting process has the highest cost of the three processes.
Laser cutting is the preferred method of producing precision sheet metal products with high consistency and repeatability.
In the heaviest thickness the punch plasma maintains a 40 percent cost advantage over laser cutting.
Fiber lasers vs co 2.
Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting.
To make your first laser cut sheet metal part you have to do the following.
The thicker the steel plate the lower the gas pressure.
And thinner while the advantage for punch plasma increases as material gets thicker.
At present steel up to 12mm in thickness is routinely cut on a commercial basis for applications in shipbuilding structural steel work off highway vehicles and many other industry sectors.
The two most common types of laser cutting machines are fiber laser and co 2.
When cutting with the nitrogen the purity of the gas should reach 99 995 ideal 99 999 which requires a higher pressure when melting and cutting thick steel plates.
Sheet metal laser cutting.
Upload it to an online laser cutting service.
We can recap the previous articles by looking at chart 1 below.
Laser cutting in the metal fabrication industry is suitable for all different kinds of materials where complex contours demand precise fast and force free processing.

The narrow slit of the laser is created to achieve high precision cutting.
Co 2 lasers use an electromagnetically stimulated gas typically a mixture.
Save it in a suitable file format check the list of online services and supported file types.
When cutting with oxygen flame the purity of gas is 99 95.
Hallmark metals performs precision metal laser cutting as part of its full service metal fabrication service.
Laser cutting is far more efficient and cost effective than traditional die stamps.
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.
Laser cutting offers a lower cost for material about 12 ga.
