Laser Cutting is an advanced manufacturing technology that utilizes high-energy-density laser beams to separate materials, offering significant advantages such as high precision, high adaptability, and a minimal heat-affected zone. Its principle involves generating a high-energy beam via fiber or CO₂ lasers, which is focused through a lens to form an extremely fine spot (approximately 0.1–0.3 mm in diameter). This spot instantly generates high temperatures on the material surface, causing melting and vaporization. Simultaneously, auxiliary gases (such as oxygen or nitrogen) blow away molten slag, forming a smooth cut seam and achieving high-quality cutting. This technology offers strong compatibility, processing various metallic materials like stainless steel and aluminum alloys, as well as non-metallic materials such as acrylic, wood, and plastics. Cutting precision reaches ±0.02 mm with excellent edge quality, typically eliminating the need for secondary processing. Compared to mechanical cutting, laser cutting is a non-contact process with no tool wear. It enables programmable automated production, delivering high efficiency and minimal deformation. It has now become one of the core processes in modern manufacturing fields such as metal processing, electronics, and automotive industries.
