As outlined by IQS Directory in their article, “Laser Cutting,” laser cutting is a precise, non-contact cutting method widely used in modern manufacturing. This technique utilizes a focused, coherent beam of light to cut through a variety of materials, including metals, wood, acrylics, and polymers, by processes such as vaporization and melting. Laser cutting’s non-contact nature means it doesn’t stress materials, allowing for clean cuts in even the most fragile and brittle substances.
How Laser Cutting Works
Laser cutting relies on Computer Numerical Control (CNC) to direct a laser beam with high precision, capable of drilling holes as small as 5 microns. This precision makes it invaluable for industries requiring intricate detail, from electronics to aerospace. The laser cutting process is subtractive, meaning it removes material rather than adding it, which makes it ideal for achieving smooth, exact edges.
Key Types of Lasers for Cutting:
- CO₂ Lasers: Common for non-metallic materials, producing wavelengths in the 9600-10,600 nm range.
- Nd-YAG (Neodymium Yttrium-Aluminum-Garnet) Lasers: Used for high-strength metals.
- Fiber-Optic Lasers: Known for precision, these lasers use a silica glass fiber core, creating a straight, narrow beam and supporting various wavelengths. Fiber-optic lasers come in single-mode (8-9 µm core diameter) and multi-mode (50-100 µm core diameter) options, with single-mode lasers offering higher precision.
Applications and Benefits
Introduced in 1965, laser cutting initially served the aerospace industry and has since become critical across multiple sectors. It allows for efficient material cutting with minimal waste and enables shaping of high-strength materials like titanium and brittle ones like ceramics. By avoiding physical contact, laser cutting minimizes material wear and offers clean, high-quality finishes.
Utilizing advanced laser cutting techniques, providing precise, high-quality cuts that meet exacting industry standards for a variety of applications.
