Sheet Metal Cutting

As one of the most advanced and popular processing technologies available today, laser cutting is widely used in the sheet metal processing industry, as it makes cutting simple, efficient and precise. GU Eagle America's fiber laser cutting machine has become an ideal choice for companies all over the world.

Application Samples
Use Cases

Our Thai customer runs a sheet metal processing business, and needed a machine that can cut large format carbon steel up to 6mm thick, stainless steel up to 4mm thick, and is also capable of cutting brass and copper.

What are the advantages compared to traditional mechanical processing?
  • High Precision: The precision levels achieved with a laser cutting machine are much higher than traditional cutting methods, and a laser beam does not wear down during the laser cutting process.
  • Improved Edge Quality: A laser, when properly focused and set for a specific material, features a thin kerf. The two sides of a kerf are parallel, and the kerf itself is vertical to the surface. The cutting precision reaches to ±0.05mm, and the cutting surface is clean with a roughness of several microns. The cut components can be put directly into use with no need for further machining. After laser cutting, the heat effected area is extremely small, and the material near the kerf remains unaffected.
  • Laser Cutting is Non-Contact: Laser cutting is a non-contact technique that means there is no material deformation. The entire process also features little to no noise, little to no vibration and no pollution.
  • Flexible Operation and High Efficiency: A laser can change programs instantaneously, with no need to change between various tools. All an operator needs to do is change the output parameter of the laser, which saves time and allows smaller production outfits to run at a lower cost. A laser can cut through any strength of material, so long as the material can melt.
  • Saves Material Scraps and Lower Power Consumption: When laser parts share a common outline, a cut can be carried out in a single process, with no scraps. A minimal scrap skeleton/outline can also be cut, some as small as a 1/6th of an inch, or even less. A typical blanking press or turret punch consumes about 50 kW total in power, whereas a 4kW laser system uses a total of about 10kW in its entirety.
  • Low Maintenance: A blanking press or turret punch often has expensive tools that must be sharpened and stored on a regular basis as different parts are cut. A laser can easily change parts simply by changing programs and requires relatively inexpensive replacement parts such as lenses and nozzles.
  • Safety: A blanking press has a large blade that moves rapidly up and down, and doesn't always have the necessary safety features to prevent hands getting caught in it. A fiber laser must be enclosed in a light proof box, which means they are designed to run without human intervention during the cutting process.

What are the advantages compared to plasma cutting?
Laser cutting on metal is more precise and uses less energy than a plasma cutting method.

Why should I choose a fiber laser over a CO2 laser?
  • There are no moving parts or mirrors in the light generating source, unlike a CO2 resonator or disk laser. This reduces maintenance requirements and operating costs.
  • A fiber laser features a much higher electrical efficiency, resulting in significantly lower operating costs. A 3kW fiber machine uses a third of the power that a 4kW CO2 machine does in most performances.
  • A fiber laser cutting machine features higher speeds when cutting thin material. Compared to a traditional 4kW CO2 machine, the fiber laser is three times faster when cutting in a straight line on 1mm thick sheets of mild, galvanized, or stainless steel, and twice as fast when cutting 2 mm thick sheets.
  • Unlike a CO2 laser, the fiber laser can cut reflective materials without fear of back reflections damaging the machine. This ensures copper, brass, and aluminum can be cut without problems.
  • A fiber laser cutting machine has 50% more time between necessary maintenance tasks that need to be completed, and 50% lower servicing costs.

What material can I cut with a fiber laser?
Fiber lasers are ideal for cutting carbon steel, stainless steel, aluminum, copper, and brass.

How thick and how fast can I cut using a fiber laser?
The thickness and speed depend on the material and laser power. The following table lists different cutting parameters with the laser source that we provide for common material.

What skills and steps do I need take in order to operate and maintain the fiber laser cutting machine?
  • The machinery and motor systems have necessary protection and lubrication systems. Users only need to clean the dust away and regularly add oil.
  • The control software uses WYSIWYG design mode, so there is no need to master G code programming skills. Additionally, we provide training services to ensure the correct operation of the laser cutting device.
  • The light is channeled and amplified through a flexible optical fiber cable, and the focusing lens is sealed in the cutting head. Users only need to regularly inspect and maintain the protection lens.
  • There are only 3 consumable parts: the nozzle and protection lens in the cutting head, and a serrated strip on the working table.
