Lasers are widely used in manufacturing and fabrication. They are an extremely effective way of cutting, marking and measuring. But how are these laser beams created? To create a laser, the energy level of atoms need to be raised to an excited state. This allows them to release light as they fall back to their original ground state. Once a beam of light is generated, it is then amplified to produce a focal point. It’s at this focal point that the laser cuts or marks the surface of a material. As the atoms move, they create a weak light. As more energy is added this light becomes more and more...
Laser cutting is precise method of cutting a design from a given material. This can be done using laser optics and CNC, these are used to direct a laser beam. The laser beam is then directed at a material which vaporises it, it can also be blown away by a jet of gas. This process leaves a clean edge with a high-quality surface finish. Laser cutting is often used because of it’s unique advantages when compared to other methods of cutting. For example, laser cutting is considered to be easier than using a mechanical cutting machine, this is thanks to the use of CAD (computer aided design) machines that automate...
Safety glasses and goggles are used in medical, military, research and education as well as industrial fields. They are crucial for the safe operation of a laser tool, safeguarding the users eyes from various hazardous effects that lasers can produce. Laser safety glasses and goggles should be manufactured to provide the highest level of protection for eyes and skin. This often means investing in certified products and avoiding the cheaper, mass-produced types. High quality glasses and goggles will be able to provide protection from the hazardous reflected or scattered high powered laser light (radiation). This includes Class 3R, Class 3B and Class 4 laser systems. When buying Laser safety glasses and goggles...
Lazer cutting is a manufacturing process which is used commonly on engineering, production and fabrication jobs. The process can eliminate the need for machining on many different jobs, allowing faster production times and a more efficient manufacturing process overall. Lazer cutting is often compared to plasma cutting as they are relatively similar processes, however lazer cutting offers several advantages. For instance lazer cutting is more precise and uses less energy when cutting durable materials such as steel and aluminium sheets. Lazer cutting is also becoming more advanced, offering the ability to cut through ever more thicker materials. The precision and quality of cut that can be achieved with a lazer is of...
Laser cut stencils are specially designed, bespoke stencils. They are made from high quality logos or artwork files that are usually created using computer image design programs such as photoshop or illustrator. Laser cut stencils are often used by businesses as they are considered to be a professional standard, this is due in large part to the accurate and clean cuts afforded by the laser cutter that transfers well onto the final image or text. Common examples include product branding, advertising, company logos and marketing stencils. Stencils can be made using physical images too. This is done by transferring a picture into a digital computer format which is then fed into a laser cutting machine...
