Laser cutting uses a powerful laser beam to focus on a material, making it melt, vaporize, or burn. A high-speed airflow then cuts through the molten material, shaping the workpiece. It’s a popular cutting method.
In laser cutting, a high-power laser is directed through optics using CNC. The laser beam or material is guided using these systems.
There are three main types of laser cutting machines based on the laser generators: CO2 and fiber laser machines.
Now, let’s briefly highlight the differences between fiber laser cutting machines and CO2 laser cutters to assist you in making the right purchase decision.
What is fiber laser cutting machine and its working theory?
A fiber laser cutting machine utilizes a fiber laser generator as its light source. This modern type of laser produces a high-energy-density beam that concentrates on the workpiece’s surface. The machine can instantly melt and gasify the targeted area using an ultra-fine focus spot. The spot’s position is controlled by a numerical control mechanical system, enabling automatic cutting.
What is CO2 laser cutter and its working theory?
The differences between fiber laser cutting machines and CO2 laser cutters?
Fiber lasers generate laser light by diode pumping and use flexible fiber optic cables to transmit the laser beam.
The CO2 laser generates laser light by exciting nitrogen and carbon dioxide gas in the cavity and then transmits the beam through a mirror.
Fiber laser cutting machine operates in the near-infrared range (around 1 micrometer) and CO2 laser cutter operates in the infrared range (10.6 micrometers).
Fiber laser cutting machine offers high precision and is well-suited for intricate designs and fine details. On the other hand, CO2 laser cutter provides good precision and versatility for a variety of applications but may have limitations in fine detail compared to fiber lasers.
Fiber laser cutting machine generally has lower operating costs due to higher energy efficiency and reduced maintenance requirements. While CO2 laser cutter may have slightly higher operating costs due to energy consumption and maintenance needs.
Unlike CO2 laser cutter has a lower initial equipment cost, fiber laser cutting machine the equipment cost may be higher than CO2.
Fiber laser cutting machine generally offers higher cutting speeds, especially for metal materials. Compared to fiber lasers, CO2 laser cutter may have slightly slower cutting speeds, particularly for metal cutting.
Photoelectric Conversion Rate:
The CO2 laser cutter has a photoelectric conversion rate of only about 10%, while the fiber laser cutting machine has a conversion rate of 30%, which is more than three times higher. This higher conversion rate saves space and reduces gas consumption, making it more effective.
Fiber laser cutting machine is more energy-efficient than CO2 lasers, providing faster cutting speeds with reduced energy consumption.
When deciding between a fiber laser cutting machine and a CO2 laser cutter, think about what you need, the materials you’re cutting, and your budget. Fiber lasers are great for cutting metal fast and precisely. CO2 lasers work well on a wide range of materials.
To sum up, fiber lasers are best for speedy, precise metal cutting, while CO2 lasers are versatile for various materials. Your choice depends on what you’re working on and the materials you use.
