Laser Cutting Thin Aluminium Sheet

Sheet metal cutting requires a power density of 10 6 watts in 2 source.

Laser cutting thin aluminium sheet.

A gantry or motion table moves the laser head and sheet metal achieving the full cut depth in a single pass. The automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal. The thinner the material the better. We cut most metals including steel stainless steel aluminum copper brass and nickel.

One of our many specialties is the cutting and shaping of thin metals. Laser cutting small parts accurately and with repeatability on thinner sheet metals does require a lower power system. Try us and see. The metal cutting option allows for accurate cutting of sheet metals like stainless steel mild steel aluminum copper and brass.

Our use of single mode lasers ensure minimal thermal distortion. Co 2 lasers use an electromagnetically stimulated gas typically a mixture. Osh cut specializes in both rapid short run and production metal laser cutting. As a reference a 40 w laser can cut through paper cardboard foam and thin plastic while a 300 w laser can cut through thin steel and thicker plastic.

Our range of laser cut widths kerfs is 10 50 microns. Many laser job shops have difficulty cutting and drilling thin metals laserod does not. On axis gas assist further reduces the head affected zone and oxidation on cuts while preventing slag on the back side. Kern s co2 and fiber laser systems can be equipped with innovative metal cutting technology.

Previously it was punched out a hole with the punch mold in the laser stamping machine then the laser began to cut through the hole. To make your first laser cut sheet metal part you have to do the following. Generally for any kind of hot cutting technology drill a small hole in the sheet metal is necessary except a few cases can start from the edge of the sheet 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.

If you wish to cut through 2 mm or thicker steel sheets you ll need at least 500 w. In the field of automobile manufacturing the cutting technology of space curves such as car roof windows has been widely used. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting.

As a sophisticated machining method laser cutting can cut almost all materials including 2d or 3d cutting of thin metal sheets. The two most common laser cutting methods are. Gas assisted thin metal cutting. If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing.

The two most common types of laser cutting machines are fiber laser and co 2. Volkswagen ag uses a 500w laser to cut complex body sheets and various curved parts. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2. Galvanometer steered thin metal.
