Width Of Laser Beam Used To Cut Sheet Metal

An example of this is shown in figure 4 where a 2 5mm wide link shape was cut in 20mm mild steel using a 3kw varimode laser operating with 5 8mm mrad beam quality at a cutting speed of 0 7m min.

Width of laser beam used to cut sheet metal.

Generally a laser s going to come in a 5 x 10 machine or maybe a 6 x 12. Fiber laser cutting equipment can cut stainless steel below 4mm and can cut up to 8 10mm thick stainless steel in laser beam if add oxygen. Because no burrs are formed secondary finishing is usually not required. Lasers were first used for cutting in the 1970s.

Any areas in your design where cut lines come closer than 0 5mm together could burn away entirely. A laser cutter is used to cut a sheet of metal. Co 2 or nd lasers being the most common. In the latter case it s often a debate between laser plasma mechanical and waterjet cutting.

A typical spot size is 600 microns or larger victor said. Image courtesy of bystronic a lot of it depends on your product and if it falls within the right range said diehl. Narrow cut feature in 20mm mild steel using 3kw varimode laser set to 5 8mm mrad beam quality. Welds generally are wider than they are deep and the slower travel gives time for the heat to conduct into the part.

Although above c0 45mm is only experienced when cutting thicker foams. The maximum thickness of cutting can be increased to 16mm but the size error of the cutting part is larger. There are several different types of lasers typically used in industrial cutting systems. This is known as the laser kerf and ranges from 0 08mm 1mm depending on the material type and other conditional factors.

However when oxygenated a thin oxide film is formed on the cutting surface. Generally the nd lasers are used for applications such as boring holes or engraving metal as well as for welding. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2. In the next few years the application of laser cutting in precision machining and micro machining will also gain substantial growth.

Conduction welding often uses a so called flat top beam. Water jet cutting can be used to cut nearly any 2d shape out of sheet metal. The width of the cuts is typically between 0 002 and 0 06 inches and the edges are of good quality.
