Selecting the best fiber laser cutting machine for your specific needs is crucial. With the technological advancements of 2024, it’s essential to consider factors such as material compatibility, cutting speed, precision, and machine features to ensure you choose a machine that meets your operational requirements. This guide aims to provide insights into the top fiber laser cutting machines of 2024, helping you make an informed decision that aligns with your business needs and technological expectations.
5 Features Enables Best Fiber Laser Cutting Machine
Fiber or CO2?
The first decision to make is whether you need a fiber or CO2 laser.
A fiber laser system is an excellent choice if your primary need is cutting metal. However, if metal cutting is only part of your work and you also need to process organic materials, a CO2 laser might be a better fit. The versatility of CO2 lasers allows you to cut a variety of materials such as plastic, wood, and fabric, in addition to metal.
While many laser systems are CO2, there are also fiber laser options available. Fiber lasers, typically ranging from 1-3kW, are particularly efficient for metal cutting.
Regardless of whether you choose a fiber or CO2 laser, it's important to prioritize a machine with high peak power for quick and effortless piercing of metal. Additionally, a quality beam delivery system that can adjust the focus dynamically is essential to handle slight movements of the metal sheet during cutting.
Beam Focus
For metal cutting, you will want to find a machine with near perfect Gaussian beam and M^2 (M squared). These are technical terms that describe a beam that comes to the same point in both the x and y axes. Without this beam characteristic, cut kerfs will be different in each axis, round parts won’t turn out perfectly round, and square parts will turn out slightly rectangular.
Cutting Head
For a metal-cutting laser system, you need to make sure you get the correct air and nozzle design. We offer a special metal cutting package for our CO2 lasers. This includes fitting the machine with our Variable Focus (V-Focus) Metal Cutting Head, which can be equipped with different nozzle sizes to achieve the best-cut quality per the metal you are processing. We also offer our Automatic Focusing Height Follower, which is a proprietary design that gives the user a z-axis control; the nozzle drops down to the metal, and if you move the metal up or down the nozzle moves with it, maintaining a constant distance between the nozzle and the material being processed. This ensures the system is delivering a consistent laser beam and airflow throughout the entire cut path.
Software
Another crucial factor for metal cutting with a laser system is optimized and flexible laser control software.
Such software often includes features specifically designed for metal cutting. For example, it allows for pierce settings tailored to penetrate the metal before starting to cut. Users can pierce with one set of settings and then switch to a different set for the actual cutting. Additionally, one assist gas can be used for piercing and another for cutting.
Flexible air control is also a significant feature. The software can manage multiple air supplies simultaneously and set pressure settings accordingly. These settings can be saved and easily recalled later.
Furthermore, the software allows users to set a lead-in to avoid an unsightly hole in the final cut shape where the beam pierces the material. A lead-out can also be programmed. The speed of the lead-in can be controlled to ramp up gradually, preventing undesirable effects at the beginning of a cut.
Optics
A final feature to consider is the optics within the laser system. High-quality lasers often include K-lenses and F-lenses positioned between the nozzle and the focusing lens to protect it. These intermediate lenses are generally more affordable and easier to replace than the focusing lens. By using these protective optics, you can extend the life of the focusing lens, reducing the need for expensive replacements. When the protective optics wear out, they can be swapped out quickly and cost-effectively, ensuring minimal disruption to your operations.
Considerations for Choosing Best Fiber Laser Cutting Machine
Material Considerations
Choosing the right machine depends on the materials you plan to cut. For metal cutting, especially with materials like iron, carbon steel, and stainless steel, a fiber laser cutting machine is highly recommended. If you frequently cut non-metal materials or thin metals, a CO2 laser cutter may be more appropriate. For cutting highly reflective materials such as aluminum and brass, it’s crucial to select a machine specifically designed to handle these materials.
