The Basics of Laser Cutting: What You Need to Know
Introduction
Laser cutting is a popular processing technique that utilizes a high-powered laser beam to precisely cut or engrave various materials. This technology has gained immense popularity in recent years due to its accuracy, speed, versatility, and ability to cut intricate designs. Whether you are new to laser cutting or considering it as a manufacturing option, this article will provide you with the basics of laser cutting and help you understand its benefits and applications.
How Does Laser Cutting Work?
Laser cutting involves the use of a highly focused laser beam that is directed onto a material’s surface, causing the material to melt, burn, vaporize, or simply be blown away by a jet of gas. The laser beam is controlled by a computer program, which determines the path and intensity of the beam. The focused laser beam allows for precise cuts, making it ideal for intricate designs and complex shapes.
The laser cutting process can be divided into three main steps:
- The laser beam is generated by a laser resonator, usually through the excitation of a gas mixture, such as CO2 or Nd:YAG.
- The laser beam is then guided and amplified by a series of mirrors and lenses before reaching the cutting head.
- The cutting head, equipped with a nozzle, focuses the laser beam onto the material, achieving the desired cut or engraving.
