When it comes to industrial cutting applications, the power and efficiency of fiber lasers are unparalleled. A common question among manufacturers and engineers is, "how thick can 6000W fiber laser cut?" This powerful piece of technology has revolutionized the manufacturing industry, enabling precise and swift cutting through various materials. The maximum cutting thickness of different materials for 6kw fiber laser cutting machine : carbon steel maximum thickness 25mm; stainless steel maximum thickness 25mm; aluminum material maximum thickness 25mm; yellow copper maximum thickness 12mm. In this article, we'll delve into the capabilities of a 6000W fiber laser, exploring the strong capability it can handle across different materials, and the factors that influence its cutting performance, etc.

What Are the Types of Laser Cutting

CO2 Lasers

A CO2 laser generates a light beam by running electricity through a gas-filled tube. This tube contains a mixture of gases, typically including carbon dioxide, nitrogen, hydrogen, and helium. The ends of the tube have mirrors, one fully reflective and the other partially reflective, allowing some light to pass through. CO2 lasers produce invisible light in the far infrared range of the spectrum, with typical industrial machines ranging from 25 to 100 watts and a wavelength of 10.6 micrometers.

CO2 lasers are highly effective for cutting non-metallic materials such as wood, paper, acrylic plastics, leather, and fabrics. They can also process certain foods, including cheese and chestnuts. While CO2 lasers can cut thin sheets of aluminum and other non-ferrous metals, their primary applications remain in non-metallic domains. Enhancing the CO2 beam’s power by increasing the oxygen content can improve cutting capabilities, but this approach requires caution and expertise.

Fiber Lasers

Fiber lasers are part of the solid-state laser family and utilize a seed laser, with amplification occurring through specially designed glass fibers energized by pump diodes. These lasers operate at a wavelength of 1.064 micrometers and are known for their extremely small focal diameters. Although they are typically the most expensive type of laser cutting machines, fiber lasers offer several advantages, including maintenance-free operation and a long service life of at least 25,000 laser hours.

Fiber lasers can achieve intensities 100 times greater than CO2 lasers with the same power output. They offer various beam settings, including continuous, quasi-, and pulsed, making them highly versatile. One notable subtype, the MOPA fiber laser, allows adjustable pulse durations for increased flexibility in applications. Fiber lasers excel at metal marking, engraving, and cutting, and can handle a wide range of materials, including metals, alloys, glass, wood, and plastics. They are particularly effective for cutting thin materials, although high-powered machines (over 6 kW) can cut materials exceeding 20 mm in thickness.

Nd:YAG/Nd:YVO Lasers

Crystal lasers, such as Nd (neodymium-doped yttrium aluminum garnet) and Nd (neodymium-doped yttrium ortho-vanadate), are known for their high cutting power. These lasers have a wavelength of 1.064 micrometers and are used in various fields, from medical and dental applications to military and manufacturing. Nd crystals offer higher pump absorption, broader bandwidth, and a broader wavelength range for pumping compared to Nd, although they have a shorter lifespan (8,000 to 15,000 hours) and higher costs.

These lasers can cut both coated and uncoated metals, non-metals, and some ceramics. Nd crystals are often combined with high NLO coefficient crystals (LBO, BBO, or KTP) to shift the output wavelength from near-infrared to green, blue, or even UV, enhancing their functionality. The ability to substitute yttrium, gadolinium, or lutetium ions with laser-active rare earth ions without significantly altering the lattice structure ensures high thermal conductivity and consistent performance.

Advantages Of Fiber Laser For Cutting

Before we delve further into the cutting capabilities of fiber laser cutting machines, let’s first take a look at the unique advantages of fiber lasers, which include the following seven points:

1. Highly Efficient Gain Medium

Fiber lasers distinguish themselves by using optical fibers doped with rare earth metal ions like ytterbium (Yb3+), neodymium (Nd3+), thulium (Tm3+), praseodymium (Pr3+), or erbium (Er3+). These ions absorb most of the pump light and emit photons at characteristic frequencies through stimulated emission. The flexible structure of fibers allows for much longer gain distances compared to other laser types, resulting in a high optical gain.

2. Smart Feedback Loop through Fiber Bragg Gratings

Instead of traditional dielectric mirrors, fiber lasers utilize fiber Bragg gratings for optical feedback. These gratings are made from glass fibers with varying refractive indices, arranged periodically to reflect the laser beam at specific wavelengths, forming the optical cavity. This means the optical cavity is integrated within the gain medium, enhancing efficiency and precision.

3. Robust Optical Cavity

Fiber lasers should not be confused with fiber-coupled diode lasers. In fiber-coupled diode lasers, optical fibers are used only for beam delivery, not for stimulated emission. Fiber lasers have an integrated optical cavity with the coiled fiber acting as the gain medium, providing a robust and stable optical cavity that enhances performance.

4. Compact Footprint

One of the significant advantages of fiber lasers is their compact design. Optical fibers are bendable and can be coiled into tight spaces, resulting in a much smaller footprint compared to other lasers with similar output powers. This flexibility allows for further customization of the optical path, making fiber lasers adaptable to various specific applications.

5. High Output Power

The thin and flexible nature of the gain medium in fiber lasers allows for several kilometers of optical fibers, achieving a high gain of the pumping light. The large surface area to volume ratio of optical fibers facilitates efficient heat dissipation, enabling fiber lasers to operate continuously at kilowatt levels without requiring complex cooling systems.

6. Excellent Beam Quality

Laser beam quality, often quantified by the M2 factor (with an ideal value of 1), measures how tightly the beam can be focused. Single-mode fibers in fiber lasers typically offer superior beam quality. This is advantageous in applications like laser cutting and welding, where high beam quality allows for a longer distance between the workpiece and the focusing object, protecting the optics from debris and fumes. The reduced beam diameter also enables finer structure manufacturing and the use of smaller, more cost-effective optical components.

7. High Reliability

Fiber lasers are highly reliable and nearly maintenance-free. The enclosed optical path within protective cladding layers makes the laser beam less susceptible to external disturbances. This results in excellent stability even in high-temperature and vibrational working conditions, making fiber lasers a dependable choice for industrial applications.

Unlocking Cutting Capability of Fiber Lasers

Fiber lasers are among the latest advancements in laser technology that have a significant impact on the manufacturing industry. They are commonly used to engrave, mark, and perform various tasks. In this blog, we will discuss why having fiber lasers in the CNC machine shop will improve efficiency and will cover topics like speed and safety.

How Thick Can A Fiber Laser Cut

Fiber laser cutting machines have different cutting capabilities depending on their power, but almost all fiber laser machines can cut a sheet of metal that is up to 13mm thick. Higher powered fiber laser machines with 10kW of power can cut mild steel up to 2mm and stainless steel and aluminium up to 30mm.

MaterialMaximum Thickness (mm)
Carbon SteelUp to 25 mm
Stainless SteelUp to 20 mm
AluminumUp to 15 mm
CopperUp to 10 mm
BrassUp to 10 mm
TitaniumUp to 10 mm

How Fast Can A Fiber Laser Cut

Fiber laser cutting speeds can vary depending on the power of the laser and the material being cut:

Power

A high-powered fiber laser cutter can be up to five times faster than a conventional CO2 laser. For example, an Accurl 10Kw Fiber Laser cutting machine can reach speeds of up to 180 m/min, while an Accurl 2Kw Fiber Laser cutting machine can reach speeds of up to 100 m/min.

Material

High-powered fiber lasers are most effective for cutting mid-range materials, such as 1/8" to ½" aluminum or mild steel, using air or nitrogen. For example, a 10kW fiber laser can cut 233% faster than a 4kW fiber laser when cutting a single 3/16" aluminum part. For steel, you'll need a minimum of 1.5 kW for material 1/4 inch thick or less, 2 kW for material 3/8 inch thick or less, and 3 kW for material ½ inch thick or less. For steel up to 1 inch thick, you can consider a laser cutter with 6 kW.

Cutting speed is measured in meters or feet per minute and is important for maintaining equipment longevity. A well-paced laser can reduce wear and tear on tools and parts, and can even cut down on power consumption. However, higher cutting speeds can also lead to cuts that are too shallow, as well as smoke and charred edges

Key Factors For Influencing Laser Cutting Quality

1. Laser Output Power and Beam Mode

The laser's power output and beam mode significantly impact cutting quality. Higher power is often necessary for thicker materials, but beam mode distribution across the cross-section is equally vital. Optimal focus ensures higher power density, leading to superior cutting quality. However, maintaining consistent beam modes throughout the laser's lifespan requires attention to factors like optical element conditions and laser working gas mixture.

2. Focus Position Adjustment

Precise adjustment of the focus position relative to the workpiece surface is essential for achieving desired cutting quality. Maintaining a constant relative position ensures stable cutting performance. The ideal focus position results in smaller slits, higher efficiency, and improved cutting speed. Adjustments typically place the focus just under the nozzle, with the distance between the nozzle and workpiece surface typically around 1.5mm. Choosing the appropriate focal length lens is critical; shorter focal lengths are suitable for high-speed cutting of thin materials, while longer focal lengths are better for cutting thick workpieces.

3. Cutting Speed

Cutting speed directly correlates with laser power density. Increasing power density enhances cutting speed, although speed is inversely proportional to material density and thickness. Factors influencing cutting speed include power level, beam mode, focus spot size, material properties, and material thickness. Enhancing cutting speed requires increasing power within a certain range, optimizing beam mode, reducing focus spot size, and selecting materials with low density and initial evaporation energy.

4. Auxiliary Gas Pressure

Auxiliary gas pressure plays a vital role in laser cutting, particularly for protecting optics, removing debris, and enhancing cutting efficiency. The choice of gas (such as compressed air, inert gas, or active gas) depends on the material being cut. Active gases like oxygen facilitate oxidation reactions, increasing cutting speed. Higher gas pressure is necessary for preventing slag sticking during high-speed cutting of thin materials, while lower pressures are preferable for reducing plastic cutting edge frosting.

How To Find A Balance Between Power and Speed

Striking the perfect balance between speed and power can be a meticulous process. Even slight adjustments can dramatically impact the cut quality.Finding the best match requires careful test cuts, experimentation, and a keen eye for detail. It’s a continuous learning curve, as different materials and intricate geometries often demand unique settings.

1. Understand the Material

Different materials react differently to laser cutting. Factors such as thickness, density, and composition affect how power and speed should be adjusted.

  • Thin materials generally require lower power and higher speed.
  • Thick materials usually need higher power and slower speed.

2. Define Your Cutting Objectives

Identify what you aim to achieve with your cut:

  • Precision: High power at a slow speed can provide a precise cut.
  • Efficiency: Lower power at higher speed can be efficient for less intricate designs.

3. Experiment with Settings

Perform test cuts to find the optimal settings:

  • Start with Manufacturer Recommendations: Begin with the settings suggested by the laser cutter’s manufacturer for the specific material.
  • Adjust Incrementally: Make small adjustments to either power or speed, and observe the effects on the cut quality.
    • Increasing Power: Results in deeper cuts but can cause burning or charring.
    • Increasing Speed: Reduces cutting time but can lead to incomplete cuts.

4. Monitor the Quality of the Cut

Assess the results based on:

  • Edge Quality: Look for clean, smooth edges without burns or melt.
  • Depth of Cut: Ensure the laser cuts through the material completely.
  • Kerf Width: Measure the width of the cut to ensure it meets your design specifications.

5. Utilize Software Tools

Modern laser cutters come with software that can help in adjusting settings:

  • Automatic Optimization: Some software can automatically suggest optimal power and speed settings based on the material and desired outcome.
  • Profiles and Presets: Save successful settings as profiles for future use.

6. Balance Power and Speed

Here are some general guidelines:

  • For Thin Materials: Lower power (20-50%) and higher speed (70-100%).
  • For Thick Materials: Higher power (60-100%) and lower speed (10-40%).

Example Workflow

  1. Choose Material: 3mm acrylic.
  2. Manufacturer Settings: Start with recommended settings (e.g., 50% power, 50% speed).
  3. Test Cut: Perform a small cut and evaluate.
  4. Adjust: If the edges are too burnt, reduce power to 40% and increase speed to 60%. If the cut isn’t complete, increase power to 60% and reduce speed to 40%.
  5. Repeat: Continue testing and adjusting until the cut meets your quality standards.

How To Find Your Best Power Solution For Laser Cutting

After discussion, we can know that the higher the fiber laser power, the thicker the metal cutting thickness. The most common cut metals are carbon steel, stainless steel, brass, and aluminum.
