What Is Laser Cutting
Laser cutting is a precise slitting process capable of cutting various metallic and non-metallic materials of different thicknesses. It operates by guiding, shaping, and focusing a laser beam that, upon contact with the workpiece, heats the material to the point of melting or vaporization. The laser beam concentrates its entire power onto a small spot, often less than half a millimeter in diameter. When the heat introduced exceeds what the material can conduct away, the laser penetrates through, initiating the cutting process.
Unlike other methods that use large-scale tools with significant force applied to the sheet metal, laser cutting occurs without direct contact. This approach prevents tool wear and eliminates deformities or damage to the workpiece. The result is a clean, precise cut, making laser cutting highly efficient for producing intricate shapes and achieving high-quality finishes in industrial manufacturing.
