The history of laser cutting technology dates back to the mid-20th century, evolving alongside advancements in laser science. In 1960, Theodore Maiman developed the world's first ruby laser, marking the dawn of the laser era. Industrial applications, however, emerged somewhat later.
In the early 1970s, CO? lasers—operating at a wavelength of 10.6 micrometers—were introduced into industry, proving highly effective for processing non-metals like textiles and paper with high precision. By the late 1970s, as laser power and technology improved, laser cutting began to be used for cutting metal sheets.
The 1980s saw the emergence of fiber lasers, which offered high efficiency and compact design, further advancing industrial laser cutting. Since the 21st century, continuous innovations have enhanced cutting speed, precision, and the range of materials and thicknesses that can be processed. Modern systems integrate advanced controls and software, enabling complex geometries and automated production.
From laboratory experiments to a cornerstone of modern manufacturing, laser cutting has rapidly evolved into a key technology in precision engineering, automotive, aerospace, and other industries.
Laser cutting uses a high-power-density laser beam to rapidly heat material to its vaporization point, creating a hole, while assist gas blows away molten material to achieve cutting. Its key advantages include:
- High precision: Laser beams can be focused to micrometer-scale spots, enabling intricate and accurate cuts.
- Small heat-affected zone: Concentrated energy and short processing time minimize thermal distortion and preserve material integrity.
- High speed and efficiency: Especially for thin sheets, laser cutting is faster than traditional mechanical methods.
- Wide material compatibility: Metals (e.g., steel, aluminum) and non-metals (e.g., plastics, ceramics) can be cut by adjusting laser parameters.
- Non-contact process: No tool wear, lower maintenance, and no surface damage.
Zinsine owns large-scale laser cutting machines with an output power of up to 20,000 watts, providing you with fast and precise steel plate cutting services.
