Percentage laser cutting sheet metal.

Sheet metal cutting requires a power density of 10 6 watts in 2 source. In the heaviest thickness the punch plasma maintains a 40 percent cost advantage over laser cutting. Since then approximately 20 000 commercial laser sheet metal cutting systems have been installed worldwide. Laser cutting process and laser cutting machine equipment are being familiar with and accepted by the majority of sheet metal processing enterprises and with its many advantages such as high processing efficiency high processing accuracy good cutting section quality and three dimensional cutting processing it gradually replaces traditional.

Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Laser cutting offers a lower cost for material about 12 ga. Save it in a suitable file format check the list of online services and supported file types. 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.

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. The thicker the steel plate the lower the gas pressure. The two most common types of laser cutting machines are fiber laser and co 2. Laser cutting is the preferred method of producing precision sheet metal products with high consistency and repeatability.

In this scenario the precision plasma cutting process has the highest cost of the three processes. 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. When cutting with oxygen flame the purity of gas is 99 95. Draw a contour of a part you want in a vector drawing software.

Fiber lasers vs co 2. To make your first laser cut sheet metal part you have to do the following. If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing. The narrow slit of the laser is created to achieve high precision cutting.

Sheet metal laser cutting. We can recap the previous articles by looking at chart 1 below. Laser cutting does not cause any deformation mainly because the workpiece needs little heat input and most of it can be cut. 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. Hallmark metals performs precision metal laser cutting as part of its full service metal fabrication service. Upload it to an online laser cutting service.
