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 thin aluminum.

One of our many specialties is the cutting and shaping of thin metals. Our range of laser cut widths kerfs is 10 50 microns. In the field of automobile manufacturing the cutting technology of space curves such as car roof windows has been widely used. The thinner the material the better.

Thin metal parts manufactures high quality components to suit the tightest specification s utilizing chemical milling electroforming and laser cutting processes. Sheet metal cutting requires a power density of 10 6 watts in 2 source. Cnc programming can also regulate power output enabling the laser to shift settings depending on the contours and thickness of the material being cut. Galvanometer steered thin metal cutting.

Laser cutting small parts accurately and with repeatability on thinner sheet metals does require a lower power system. Try us and see. An emphasis on hybrid fabrication allows us to mix processes providing a broader overall product offering and better customization for our clients. Using a high power laser machine on thin metals can create several problems that could be avoided with a lower powered machine.

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 automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal cutting. If you wish to cut through 2 mm or thicker steel sheets you ll need at least 500 w. Unlike many chemical etching companies that only specialize in a.

The moveable laser can perform fast cutting operations while maintaining accuracy and is highly effective on thin sheet metal. As a sophisticated machining method laser cutting can cut almost all materials including 2d or 3d cutting of thin metal sheets. The metal cutting option allows for accurate cutting of sheet metals like stainless steel mild steel aluminum copper and brass. Most laser cutting machines are controlled by cnc programs or made into cutting robots.

Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2. Using a galvanometer to steer the beam is an alternative method for laser cutting thin metals. 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.
