Laser Cutting Thin Aluminum

Our range of laser cut widths kerfs is 10 50 microns.

Laser cutting thin aluminum. Our use of single mode lasers ensure minimal thermal distortion. Sheet metal cutting requires a power density of 10 6 watts in 2 source. 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. Galvanometer steered thin metal cutting.

In the field of automobile manufacturing the cutting technology of space curves such as car roof windows has been widely used. 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. The moveable laser can perform fast cutting operations while maintaining accuracy and is highly effective on thin sheet metal. If you wish to cut through 2 mm or thicker steel sheets you ll need at least 500 w.

Otherwise you are simply using a sledgehammer to crack nuts and losing yourself money for doing so. Thin metal parts manufactures high quality components to suit the tightest specification s utilizing chemical milling electroforming and laser cutting processes. Most laser cutting machines are controlled by cnc programs or made into cutting robots. The computer controlled galvanometer enables high speed cutting patterns as well as multiple repetitions of the same pattern in quick succession reducing heat induced strain on the part.

Laser cutting small parts accurately and with repeatability on thinner sheet metals does require a lower power system. Many laser job shops have difficulty cutting and drilling thin metals laserod does not. An emphasis on hybrid fabrication allows us to mix processes providing a broader overall product offering and better customization for our clients. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.

Using a high power laser machine on thin metals can create several problems that could be avoided with a lower powered machine. One of our many specialties is the cutting and shaping of thin metals. The metal cutting option allows for accurate cutting of sheet metals like stainless steel mild steel aluminum copper and brass. As a sophisticated machining method laser cutting can cut almost all materials including 2d or 3d cutting of thin metal sheets.

Using a galvanometer to steer the beam is an alternative method for laser cutting thin metals. Unlike many chemical etching companies that only specialize in a. The automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal cutting.
