Cutting copper plates with a laser is more challenging than other materials. The specific reasons are as follows:

• High Thermal Conductivity: Copper is one of the most thermally conductive of the common metals, meaning it can transfer heat quickly across its surface. When laser cutting copper, the heat generated in the process is quickly dissipated into the surrounding material, making precise and controlled cuts difficult.
• Softness And Ductility: Copper is a relatively soft and ductile metal. While its malleability makes it useful in many applications, it can pose challenges during processing. Copper’s softness can cause it to deform or warp easily during cutting or forming. It may be more prone to burrs or irregularities that affect the quality of the finished product.
• Oxidation And Surface Treatment: Copper reacts readily with oxygen in the air, causing a thin oxide layer to form on its surface. This oxide layer interferes with the laser cutting process, affecting cut quality and causing irregularities. Special measures may be required to remove or mitigate the oxide layer prior to cutting, such as the use of nitrogen or assist gases to create an inert environment.
• Heat Affected Zone: When laser cutting copper, the high thermal conductivity of copper results in a large heat affected zone (HAZ) around the cut. The heat-affected zone is the area around the cut where the heat generated by the laser-cutting process can affect the properties of the material. A larger heat-affected zone in copper results in more severe thermal distortion and may require additional post-processing steps to achieve the required accuracy. Controlling the heat-affected zone helps maintain the desired cut accuracy and quality.
• Reflectivity: Copper is highly reflective to many wavelengths of light, including those commonly used in laser cutting. This reflection causes the material to absorb less laser energy, reducing the efficiency of laser-cutting copper. The reflective nature of copper requires laser systems with higher power and specific wavelengths to overcome this limitation.
• Material Thickness: Processing thicker copper plates can be more challenging due to increased thermal conductivity and heat dissipation. Achieving clean cuts and maintaining tight tolerances can be more difficult with thicker copper plates.

Despite these challenges, it is still possible to effectively laser cut copper with the correct equipment, laser parameters, and technique. Dedicated laser systems designed for copper processing, such as those with higher power and customized beam characteristics, can help overcome difficulties associated with copper cutting. Additionally, employing proper assist gas, controlling cutting speed, and optimizing laser parameters can improve cut quality and minimize issues related to thermal effects and surface oxidation.

Fiber laser generators are ideal for cutting copper plates due to their high absorption rate on copper materials. Using a high-power fiber laser generator can effectively cut copper plates of different thicknesses. The maximum thickness of copper that can be laser cut with a fiber laser generator depends on several factors, including the power of the laser system and the specific characteristics of the material being cut. While fiber lasers can cut thicker copper plates than CO2 lasers, there are still some practical limitations to consider.

Generally speaking, copper plates with a thickness of about 20-25 mm (0.8-1 inch) can be effectively cut with a high-power fiber laser cutting machine. However, it should be noted that cutting thicker copper plates may require a dedicated fiber laser cutting machine with higher power output and optimized cutting parameters. Additionally, the required cut quality, precision, and speed also affect the maximum thickness that can be efficiently achieved.

It is worth noting that the maximum thickness cut thickness may vary depending on the power, beam quality, and other factors of a particular fiber laser system. Additionally, the required cut quality and precision also play a role in determining the actual maximum thickness. Manufacturers or suppliers of fiber laser cutting machines can provide more precise information on the maximum thickness they recommend cutting copper sheets with their particular equipment. Testing or consulting a fiber laser cutting expert can help determine the maximum thickness that will meet your specific requirements.

The laser-cutting copper plates present certain risks that need to be considered and addressed to ensure safety and minimize potential hazards. Here are some of the risks associated with laser cutting copper:

• Eye And Skin Hazard: Laser cutting copper involves using a high-powered laser generator to deliver an intense and focused beam of light. Direct exposure to laser radiation may cause serious eye damage, including permanent vision loss. The laser beam can also burn or cause skin damage. It is crucial to take proper safety measures, such as wearing laser safety glasses, and protective clothing, and making sure access to the laser cutting area is restricted.
• Toxic Fumes And Particles: Laser-cutting copper can release toxic fumes and particles, especially as the copper oxidizes during the cutting process. Inhalation of copper oxide fumes may be harmful and the fine particles released may be a respiratory hazard. Personal protective equipment (PPE) such as adequate ventilation, extraction systems, and respirators should be used to minimize exposure to these hazards.
• Fire And Combustion Hazard: Copper is a highly thermally conductive material and generates a lot of heat during laser cutting. There is a risk of fire if combustible materials such as flammable gases or nearby objects come into contact with the laser beam or heated copper. Having proper fire suppression systems, fire-resistant work surfaces and clear safety protocols can help prevent and manage potential fire incidents.
• Electrical Safety: Copper is an excellent conductor of electricity, and electrical components and systems may be involved when laser-cutting copper plates. It is important to follow electrical safety guidelines, such as ensuring proper grounding, handling electrical connections safely, and using proper electrical protective devices to reduce the risk of electric shock or accidents.
• Reflection Hazard: Copper is highly reflective for many laser wavelengths, which means that laser beams can reflect off copper surfaces and pose a risk to the operator or nearby individuals. Reflections may cause accidental exposure to laser radiation, which may cause eye damage. Adequate safety measures, such as enclosure systems and beam path shielding, should be taken to minimize the risk of reflections.
• Thermal Burns And Heat-Related Injuries: During laser cutting, the copper plate and surrounding area can become very hot. Nearby operators or individuals may be at risk of thermal burns or heat-related injuries if they come into contact with hot materials or surfaces. Proper training, use of proper personal protective equipment, and following safety procedures can help prevent such injuries.
• Machine Failure: Laser cutting machines, like any mechanical and electrical equipment, may experience failure. These unexpected events can pose risks to the operator and the surrounding environment. Regular maintenance, proper training, and following safety guidelines help minimize the risk of machine failure and associated hazards.

To mitigate these risks, it is critical to follow the safety guidelines provided by the laser cutting machine manufacturer and comply with relevant safety regulations and standards. Implementing proper safety training for operators, use of personal protective equipment (PPE), maintaining a safe work environment, and having proper safety protocols in place is critical to minimizing the risks associated with laser cutting copper plates.

Yes, laser cutting machines often require the use of assistive technology, such as gas, to effectively cut copper plates. Copper is a highly reflective material and has high thermal conductivity, which makes it challenging to laser-cut copper plates alone. The auxiliary technology used is usually present in the running of gases, such as oxygen or nitrogen, which help to improve the cutting process and achieve better results.

The most commonly used assist gas when cutting copper is nitrogen (N2). Nitrogen assists the cutting process by displacing oxygen around the laser beam, preventing oxidation and producing a clean and smooth cut. The nitrogen creates an inert environment that prevents the copper from reacting with the oxygen in the air. Nitrogen also helps cool the copper during cutting and reduces the risk of burr or dross formation.

In some cases, oxygen (O2) can also be used as an assist gas for cutting copper. When the laser beam interacts with the copper plate, oxygen aids the combustion process, providing additional heat to melt and remove material. But it can cause more oxidation and produce rougher edges. Therefore, nitrogen is generally preferred for copper plate cutting to achieve higher quality and precise cutting.

It is important to note that the exact gases and parameters used may vary depending on the laser cutting machine and desired cut quality.

Our engineers will provide you with detailed instructions on recommended gases and settings for effective copper cutting.

The dimensional accuracy of a laser cutting machine used to cut copper can vary depending on a number of factors, including the design of the machine, laser power, beam quality, control system, and the thickness and properties of the copper being cut. Achieving high dimensional accuracy in copper plate cutting can be challenging due to the thermal conductivity and reflectivity of the material.

For copper plate cutting, the laser cutting machine can usually achieve a dimensional accuracy of ±0.01 mm to ±0.05 mm. But achieving the highest level of precision may require careful calibration, proper machine maintenance, and fine-tuning of cutting parameters. In addition, achieving precise dimensions may depend on design complexity and the specific characteristics of the copper being cut.

The high thermal conductivity of copper results in heat dissipation and possible thermal distortion during the cutting process. The reflectivity of copper can also cause the scattering of the laser beam, thus affecting the cutting accuracy. These factors may cause slight deviations or tolerances in the final dimensions of cut copper parts.

In order to minimize these effects and maintain dimensional accuracy, copper plate laser cutting machines usually use advanced control systems, adaptive optics, real-time monitoring and compensation algorithms, and other functions. These techniques help minimize distortion and compensate for any thermal effects during cutting. In addition, optimizing cutting parameters such as laser power, cutting speed and assist gas can also help to achieve the required dimensional accuracy.
