Introduction: The Evolution of Metal Cutting
Metal cutting had come a long way since its early days when manual tools were predominantly used. With the advent of industrialization, mechanized cutting techniques such as sawing and shearing gained popularity. However, these methods often needed more precision and required extensive manual labor. The introduction of laser cutting machines revolutionized metal cutting, providing a highly efficient and accurate alternative.
Understanding Laser Cutting Machines
Laser-cutting machines utilize the power of concentrated laser beams to cut through various materials, including metals. The laser beam is directed by computer numerical control (CNC), ensuring precise and intricate cutting patterns. Laser cutting machines are available in different configurations, such as CO2 and fiber lasers, each offering distinct advantages depending on the application.
How Laser Cutting Works
Laser-cutting machines generate a coherent beam of light through the stimulated emission of photons. This concentrated light energy is directed onto the workpiece, melting or vaporizing the material along the predetermined cutting path. The high intensity and focused nature of the laser beam allow for exceptional cutting accuracy, even for intricate designs.
