Laser cutting is a highly specialised manufacturing process. It requires specialised equipment which is often expensive, as well as knowledge of lasers and technical knowledge. This post looks at the way lasers work to carry out their function. A laser beam is composed of a column of very high intensity light, consisting of a single wavelength or colour. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The beam itself is only around 3/4 of an inch in diameter. It travels from the laser resonator, which creates the beam, through the machine’s beam path. After...
After using CO2 cutting machines for over 2 decades, fibre laser was introduced and gained legal acceptance in 2008. Since then, many industries have opted for fibre laser cutting machines in various applications that including cutting metals, thin and thick flat surfaces. Although only a couple of manufacturers existed when this powerful cutting machine was accepted, the number has tremendously risen and several brands now exist in the market. Landing a fibre laser should not be an overwhelming task. However, not all such machines you find will depict desirable characteristics. You must therefore carefully examine its mode of functioning, vulnerabilities, ease of use and durability among other things. Here are...
Lasers are perfect for making precision cuts, and no less so on paper and cardboard products. Being particularly suited for cutting fine geometries with maximum precision and quality, Laser paper cutting allow for cutting even the most delicate paper constructions, and creating a professional and clean, finished product. Its important to note that when cutting paper with lasers, the paper can sometimes burn. Just like wood, which has a similar chemical composition, paper is evaporated suddenly. This is called sublimation. In the area of the cutting clearance, the paper escapes in gaseous form, which is visible in the form smoke (at a high rate). This smoke transports the heat away from the paper, meaning...
Customised engraving services have been offered by many companies over the years. However, it goes without saying that laser engraving is one of the major revolutions of the modern era. The best aspect about this service is that the laser engraving machine that is used does not come in direct contact with the surface. Using laser has made the etching process simpler than ever. It is not only effective in carving a surface, but is also a cost-effective means of passing on a message to a loved one or promoting a business. On the Internet, individuals can come across a number of service providers offering technology for engraving. It is...
To produce complex contours on metals or metal sheets, you need to use a laser cutting machine. However, the quality of the cut depends on the machine and the training of the operator. The laser beam is shot at an average diameter of 0.15 mm, thus it will only cut within that range. The cutting beam produces power that falls anywhere between 1000 to 2000 watts. The overview When laser cutting UK operators work on a piece of metal, electronic data is inputted from a computer-aided drawing design to produce parts of great complexity. The tool also uses a computer software to produce the intended output. However, it only works...
