Investing in laser cutting technology involves considering various factors, with price being a significant consideration. Fiber laser cutting machines and CO2 laser cutting machines are two prominent options in the market, each with its advantages and price considerations. Understanding the differences in pricing between fiber and CO2 lasers is crucial for making an informed decision. In this ultimate guide, we’ll delve into the factors that influence the fiber laser cutting machine price versus CO2 lasers, helping you determine which option best fits your needs and budget.

Overview of Fiber Laser and CO2 Laser Technology

Introduction to Fiber Laser Cutting

Fiber laser cutting utilizes a solid-state laser to generate a high-intensity laser beam. The laser beam is transmitted through a flexible fiber optic cable to the cutting head, where it is focused onto the workpiece surface. Fiber lasers are known for their efficiency, precision, and versatility in cutting a wide range of materials.

Merkmale

Fiber lasers represent a cutting-edge technology in laser cutting, utilizing a solid-state laser medium, typically doped fibers, to generate a highly concentrated laser beam. This design allows for several significant advantages. They offer exceptional power density, enabling faster cutting speeds and ensuring superior cutting quality compared to other types of lasers. This high power density is particularly advantageous for achieving precise cuts, even in thick metal materials.

Moreover, fiber lasers are highly efficient in converting energy into laser light, making them more energy-efficient and cost-effective to operate. Their efficiency contributes to reduced energy consumption and lower operating costs over time. As a result, fiber lasers have gained widespread adoption in industrial applications, particularly for cutting metals such as steel, aluminum, copper, and brass.

Their versatility and reliability make fiber lasers increasingly popular across various industries. Manufacturers appreciate their consistent performance, high precision, and low maintenance requirements, making them indispensable tools for metal fabrication and manufacturing processes. In essence, fiber lasers have transformed metal cutting processes, offering faster production times and higher-quality results, thus meeting the demands of modern industrial applications.

Introduction to CO2 Laser Cutting

CO2 laser cutting technology relies on a gas mixture excited by an electrical discharge to produce the laser beam. This beam is then directed through mirrors and a focusing lens to the cutting head. CO2 lasers have been a staple in laser cutting for decades and are valued for their versatility across various materials.

Merkmale

CO2 lasers rely on a gas mixture, usually containing carbon dioxide, nitrogen, and helium, to generate the laser beam. This gas mixture is excited by an electrical discharge, resulting in the emission of a high-energy laser beam. One of the key features of CO2 lasers is their ability to provide good beam quality, making them suitable for a wide range of cutting applications.

These lasers are effective for cutting both non-metallic materials and metals with precision. They are widely used across industries for cutting materials such as wood, acrylic, plastic, fabric, and thin metals. The versatility to work with such a variety of materials makes CO2 lasers highly valuable in applications like signage, packaging, textiles, and more.

Moreover, CO2 lasers are capable of cutting thicker materials compared to fiber lasers, thanks to their longer wavelength (around 10.6 micrometers). This longer wavelength allows for deeper penetration into the material, making CO2 lasers preferable for applications where cutting through thicker materials is necessary.

What’s Main Difference Between Fiber and CO2 Lasers

The main difference between a CO2 and a fiber laser is the wavelength of the beam. This determines the type of material each laser can process. The wavelength of the two lasers is shown below: 

The shorter wavelength of a fiber laser makes it particularly well-suited for cutting metals as more of the beam’s energy is absorbed into the material and less is reflected, resulting in more efficient cutting compared to CO2 lasers.

Additionally, the spot size of a laser plays a crucial role in determining the kerf width, which affects cutting precision. Fiber lasers typically have smaller spot sizes, leading to higher precision during cutting and higher optical densities (the laser power per unit area). In contrast, CO2 laser spot sizes can be significantly larger, up to 90% larger than those of fiber lasers.

Fiber lasers offer flexibility with the option of either zoom or non-zoom cutting heads. Zoom heads allow for adjusting the focus spot diameter and, consequently, the kerf width. This feature enables thicker sheets to be cut efficiently using the same power laser. On the other hand, CO2 machines use different heads and lenses to achieve various spot sizes, but they lack the adjustability of spot size that fiber lasers offer.

Another difference between the two is the price. In fact, fiber laser technology is more expensive than CO2 technology.

Why Fiber Laser Cutting Machine Price Is More Expensive

Several factors contribute to the higher cost of fiber lasers compared to CO2 lasers:

Technology and Materials

Fiber lasers require advanced technology and high-quality materials, such as semiconductor diodes, which are more expensive to develop and maintain than CO2 laser components.

Efficiency and Performance

Known for their superior efficiency and performance, fiber lasers deliver better beam quality, faster processing speeds, and lower energy consumption. These sophisticated features and capabilities contribute to the higher cost of fiber lasers.

R&D

The development and refinement of fiber laser technology demand substantial investment in research and development, which is reflected in the overall cost of these systems.

Customization and Integration

Fiber lasers are often integrated into complex manufacturing systems and tailored for specific purposes. This necessitates additional engineering and integration efforts, further contributing to their higher overall cost.

In summary, the advanced technology, enhanced performance, and specialized materials used in fiber lasers, along with significant investment in research and development, all contribute to their higher cost compared to CO2 lasers. However, the benefits of improved efficiency, performance, and productivity often justify the investment in many industrial applications.

Cost Considerations and Suitability

Initial Purchase Cost

When considering the upfront cost, fiber laser cutting machine prices are generally more expensive than CO2 laser cutting machines. This is primarily due to the advanced technology utilized in fiber lasers, such as diode pumping and fiber optic cables, which are more costly than the components used in CO2 lasers, like CO2 laser tubes and auxiliary gases.

Betriebskosten

Despite the higher initial investment, fiber laser cutting machines offer significant advantages in terms of operating costs. Fiber lasers boast an electrical-to-optical conversion efficiency of around 30%, compared to the 10% efficiency of CO2 lasers. This higher efficiency means that FLCs consume less electricity for the same cutting tasks, leading to substantial energy cost savings over time. Additionally, fiber lasers do not require additional working gases, while CO2 lasers consume a considerable amount of gases during operation, adding to their running costs.

Maintenance Costs

Fiber laser cutting machines also have a distinct advantage regarding maintenance costs. The modular and redundant design of fiber lasers, combined with the absence of optical mirrors in the resonator cavity, simplifies maintenance. In contrast, CO2 lasers have a more complex structure, and their optical mirrors are prone to damage and costly to replace, resulting in higher maintenance expenses.

Processing Efficiency

In terms of processing efficiency, fiber laser cutting machines outperform their CO2 counterparts. FLCs possess a higher laser beam density, intensity, brightness, and conversion rate, enabling them to cut thin metal sheets 2-3 times faster than CO2 lasers with the same power output.

Material Suitability

Another important factor is the suitability of each technology for different materials. Fiber laser cutting machines are more adept at cutting metals, while CO2 laser cutting machines excel with non-metallic materials. If your business primarily involves cutting metal sheets, an FLC may be the better choice.

In summary, while fiber laser cutting machines have a higher initial purchase cost, their lower operating and maintenance costs, superior processing efficiency, and suitability for metal cutting make them a compelling option for many industrial applications.

Cost Analysis: Which Is More Cost-Effective?

Cutting Speed: Comparative Efficiency

When it comes to cutting speed, fiber lasers demonstrate significant advantages over CO2 lasers, especially with thin sheets (< 8 mm) and stainless steel. For instance, for a 1 mm sheet, fiber lasers can cut up to 6 times faster than CO2 lasers. This speed difference decreases to around 2 times faster for a 5 mm sheet.

Increasing the laser source power by just 2 kW can enhance cutting speeds by 2-3 times for thin sheets. As sheet thickness increases (at the same laser power), CO2 lasers can match and sometimes exceed fiber laser cutting speeds, though the difference remains minimal compared to thinner sheets.

High-power CO2 lasers (above 6 kW) are less common than their fiber laser counterparts. Therefore, for machines with higher power requirements, fiber lasers achieve faster cutting speeds across all sheet thicknesses.

It’s important to note that the optimal cutting speed isn’t always the fastest. Efficiency and cost-effectiveness considerations often prioritize factors like consumable lifespans and gas usage.

Investment Costs: Comparing Machine Acquisition

The acquisition cost of a laser machine is influenced by several factors, including:

• Laser power
• Cutting area
• Automation levels

For industrial purposes, a second-hand CO2 laser system can start at approximately £150,000 and can go up from there.

New industrial fiber laser machines typically range from £275,000 to £550,000, with some models reaching up to a million pounds. However, the cost of laser systems, particularly those utilizing solid-state technology, is gradually decreasing as this technology gains popularity.

Similarly, a new CO2 laser system also falls within a comparable price range. It’s worth noting that while the prices for CO2 laser sources have stabilized, advancements in solid-state lasers are influencing overall laser system costs.

Maintenance Costs and Requirements

Fiber lasers exhibit significantly lower maintenance needs compared to CO2 lasers, primarily due to their distinct beam delivery systems.

Fiber lasers utilize a monolithic configuration where the laser beam travels through a fiber optic cable to reach the cutting head. This design protects the optics path entirely from contaminants. The primary consumables for fiber lasers are the nozzle (similar to CO2 lasers) and the protective window.

In contrast, CO2 lasers employ bend mirrors housed within bellows, sometimes filled with nitrogen, to deliver the beam to the cutting head. Over time, these mirrors and bellows accumulate dirt and require regular cleaning or replacement to maintain cutting performance. The repetitive motion of the machine can also lead to wear and tear on the bellows, causing holes.

Due to their more exposed beam delivery system, CO2 lasers are susceptible to greater variability in laser quality and output, influenced by environmental factors such as temperature and moisture. The heat generated by CO2 lasers can distort mirrors, leading to decreased power delivery to the cutting head and necessitating adjustments in cutting parameters, which can be time-consuming.

A significant maintenance concern with CO2 lasers is the potential for damage to the expensive oscillator if the laser beam reflects back down the delivery system. Maintenance for a CO2 laser cutting head typically requires 4-5 hours per week, whereas maintenance for a fiber laser is generally less than half an hour per week.

Aligning the laser beam is crucial to ensure uniform cutting quality across all edges of a profile. Misalignment, often caused by collisions between the cutting head and materials, is more complex and time-intensive to correct in CO2 lasers due to their multiple-mirror beam delivery systems. In contrast, fiber lasers require adjustment of a single lens for alignment purposes.

In summary, while both CO2 and fiber lasers require regular maintenance, fiber lasers offer lower maintenance costs and simpler upkeep due to their protected beam delivery system and reduced susceptibility to environmental factors.

Auxiliary Gas Usage

Due to the smaller spot size and resulting narrow kerf width of fiber lasers, higher gas pressures are required to effectively expel the molten material during cutting.

However, by carefully adjusting cutting parameters such as speed and focal position, and by optimizing gas pressure and nozzle size, it is possible to minimize gas consumption.

Below table displays the gas pressure and nozzle size utilized for cutting the aforementioned samples, as well as the associated costs using both a 6 kW fiber laser and CO2 laser.

In conclusion, when cutting stainless steel, a fiber laser typically consumes approximately 40% more nitrogen per hour compared to a CO2 laser. For cutting mild steel, the consumption of oxygen is approximately 20% higher with a fiber laser. If you primarily work with stainless steel and are seeking more information on fiber laser cutting machines, we recommend referring to this comprehensive guide on finding the best stainless steel fiber laser.

Electricity Costs

When comparing electricity costs, fiber lasers emerge as more economical and environmentally friendly than CO2 lasers.

CO2 lasers operate at an efficiency of around 10%. For instance, to power a 6 kW CO2 laser, a 60 kW power supply is necessary. In contrast, fiber lasers are considerably more efficient, typically around 45% to 50%. This means that a 6 kW fiber laser requires only a 13 kW power supply.

As laser power increases, so does the demand for electricity due to the requirement for a larger chiller. However, even at similar power levels, the electricity costs for operating a CO2 laser’s chiller are generally higher than those for a fiber laser.

The electrical needs of the extraction system vary with the required size: as laser power and cutting table area increase, so too does the power demand of the filtration system.

In summary, the markedly lower electricity costs associated with fiber laser machines can lead to substantial savings in operational expenses for various cutting applications.

Abschluss

Despite being an older technology, CO2 lasers still excel, particularly in cutting non-metals.

However, the significant advantages of fiber lasers—including speeds up to five times faster on thin materials (< 8 mm), 50% lower operating costs, and higher productivity—can lead to transformative financial benefits.
