Cutting is one of the fundamental processes for sheet metal fabrication. Metal fabricators have several options for cutting metallic materials, including turret punch, laser cutting, plasma cutting, and autogenic flame cutting among other methods. Laser cutting stands out for its high degree of precision and speed. Fiber laser cutting offers even greater advantages, which we will explore in this blog.
About Fiber Lasers
Fiber lasers have a short history compared to other methods. The road to their use began when the foundation (fiber optics) was developed in the 1960s, although cutting with a fiber laser wouldn’t be commercially viable until the 1990s. Fiber laser cutting involves using a high-powered laser beam to precisely cut materials. The laser is generated through optical fibers doped with rare-earth elements, which amplify the light and create a highly focused and intense beam. The working principles of fiber lasers—efficient light generation, high beam quality, robust and compact design, scalability, high electrical-to-optical efficiency, and minimal thermal effects—combine to provide significant benefits.
Enhanced Precision and Accuracy
One of the most significant benefits of fiber laser cutting is its precision. The focused laser beam allows for extremely fine cuts, which is essential for intricate designs and detailed work. This level of accuracy ensures minimal material wastage, leading to cost savings and more efficient use of resources. The precision and accuracy allow us to achieve:
- Tight Tolerances – Fiber laser cutting machines can maintain tight tolerances, ensuring that parts fit together perfectly without the need for additional machining.
- Consistent Quality – The precision of fiber laser cutting ensures consistent quality across all pieces, reducing the risk of errors and rework.
- Non-Contact Cutting – Unlike some other methods, fiber laser cutting doesn’t involve physical contact with the material, preserving cut quality.
- Less Material Stress – Fiber laser cutting produces a minimal heat-affected zone due to the precise, localized heating, making it suitable for materials where minimal thermal distortion is critical. It also induces minimal mechanical stress, leading to higher overall quality and reliability.
Increased Productivity
Fiber laser cutting is significantly faster than traditional cutting methods, such as CO2 lasers or mechanical cutting. The high-speed capabilities of fiber lasers translate into increased productivity and shorter lead times.
- Faster Cutting Speeds – Fiber lasers can cut through materials at speeds up to three times faster than CO2 lasers, particularly when used with thin materials.
- Reduced Downtime – The reliability and durability of fiber lasers means less downtime for maintenance and repairs, further enhancing productivity.
- Reduced Set-Up Time – Traditional methods require extensive manual adjustments and tooling changes during setup. CO2 lasers require precise mirror alignment and beam path calibration; however, fiber lasers eliminate these needs with flexible beam delivery, lower maintenance, and advanced automation, significantly reducing setup time.
Cost-Effectiveness
While the initial investment in fiber laser cutting technology may be higher, the long-term cost benefits are substantial – savings we can pass on to our clients. The efficiency, speed, and precision of fiber laser cutting contribute to overall cost savings in several ways.
- Lower Operating Costs – Our fiber laser consumes less power than CO2 lasers, requires less maintenance than CO2 lasers, and can be operated with shop air, resulting in lower operating costs.
- Reduced Material Waste – The precision of fiber laser cutting minimizes material waste, leading to cost savings on raw materials.
Versatility in Material Handling
Fiber laser cutting is highly versatile and capable of cutting a wide range of materials and thicknesses, including stainless steel, aluminum, brass, copper, and more. This versatility makes it a valuable tool for various applications in metal fabrication. Key benefits include:
- Cutting Diverse Materials – Fiber lasers can easily handle different types of metals, making them suitable for diverse projects and industries.
- Thickness Range – Fiber lasers can cut through thick (25mm) and thin (0.76 mm) sheets, providing flexibility in material choice.
Environmental Benefits
In addition to operational advantages, fiber laser cutting is more environmentally friendly. The technology offers several ecological benefits that align with sustainable manufacturing practices.
- Energy Efficiency – Fiber lasers are more energy-efficient than CO2 lasers, reducing the overall carbon footprint of the cutting process.
- Cleaner Cutting Process – The precision of fiber laser cutting reduces the need for secondary processes like deburring or grinding, leading to less material waste and fewer emissions.
Ease of Automation
Fiber laser cutting machines are compatible with advanced automation technologies, which can further improve efficiency and productivity in metal fabrication.
- Integration with CAD/CAM – Fiber lasers can easily integrate with computer-aided design (CAD) and computer-aided manufacturing (CAM) software, allowing for seamless automation of cutting processes.
- Automation – Automation that handles loading and unloading allows us to run a full 8 hours unmanned.
