What is laser cutting?
Laser Cutting Machine Before we take a dive straight into the world of fiber laser cutting, it’s important to understand the general scope of laser cutting. Industrial manufacturing uses this type of technology for high-power outputs to melt, burn, vaporize or blow away the material, leaving an edge with a high-quality surface finish. It allows us to reduce setup time, cut the need for custom tooling, and provide grilles in heavier gauges that could not be punched.
Laser Cutting Machine consists of two categories: laser fusion cutting and ablative laser cutting. This engineer’s guide to laser cutting explains how fusion cutting melts the material before using a high-pressure stream of gas to remove the metal. Ablative cutting uses a pulsed laser to remove the metal.
Fiber laser, gas laser and crystal laser make up the three most notable types of laser cutting machines. CO2 is one of the most popular types of gas lasers, where the gas transmits through a beam guided by mirrors. This process can cut plastic, Plexiglas, metals, and wood. Crystal lasers use crystals, like neodymium-doped yttrium aluminum garnet, to produce high-powered cutting. They are more archaic and, therefore, have a shorter lifespan (8,000-15,000 hours). Fiber lasers use optical fibers doped in rare elements to create quick, clean cuts using an automated system that is easy to maintain should any errors occur.
