Advantages of 3D / 5 Axis Laser Cutting
Laser cutting is versatile, 3D laser cutting even more so. Typically, lasers can provide cutting, drilling, engraving, ablation and structuring as well as welding for many materials in many configurations. At EB Industries we can handle materials from 0.001” to well over 0.500” (at slower feed speeds) and cut a range of materials including plastic, glass, wood, and all metals. Laser cutting is extremely precise: the minimum size of the kerf can be as fine as 0.006” and, with a 5 axis fiber laser, the beam can be accurately placed in three dimensions. The small heat-affected zone of a laser reduces potential distortion and warping of the material that is being cut and the finished cut edge typically exhibits a high-quality surface finish and minimal to no material contamination. 5 axis laser cutting also means that a part can be shaped and formed before it is cut, which in many cases results in faster production speeds and an overall stronger finished piece.
Laser cutting uses a highly coherent beam of light focused on the work piece, with power applied such that the material either melts, burns, vaporizes away, or is blown away by a jet of gas. 3D laser cutting allows for quick forming of complex parts at high production rates, while 2D laser cutters are used for flat-sheet materials as well as structural and piping materials.
Industrial lasers for cutting metal are generally of two varieties, CO2 gas or solid state fiber. Fiber lasers have additional advantages in terms of power, flexibility and precision but, regardless of the technology used, laser cutting is fast, accurate and precisely repeatable. While the optimum technology for an application is, of course, dependent on the parameters of the application, few manufacturing processes can compare with 3D laser cutting with respect to speed, precision and cost of cut.
Materials and Depth of Cut
EB Industries cutting capabilities range from very thin to thick sheets. Many factors can influence the depth of the cut and the speed of the cut. The following table provides some rough guidelines:
|Material||Processing||Max. material thickness||Max. cutting speed|
|Mild Steel||Oxygen||0.315 inch (8 mm)||6.2 inch/sec (9.5 m/min)|
|Mild Steel||Nitrogen||0.157 inch (4 mm)||25.6 inch/sec (39 m/min)|
|Stanless Steel||Nitrogen||0.157 inch (4 mm)||27.6 inch/sec (42 m/min)|
|Aluminum||Nitrogen||0.157 inch (4 mm)||13.1 inch/sec (20 m/min)|
