How many types of fiber laser cutting machines are there, and how are they different?
Many businesses are probably familiar with laser cutting machines. In the past, laser cutting machines were used in the jewelry industry to drill holes in diamonds. Later, laser cutting machines were developed to be able to cut other types of metals, such as steel, titanium, and stainless steel. However, many businesses purchase laser cutting machines but do not clearly understand how they work. They also do not know the types of laser cutting machines and their applications. In fact, it is not difficult to learn. A laser cutting machine is not just a small box that shoots a red dot. It is also used in many manufacturing processes. It can cut both metals and non-metals. But what about fiber laser cutting machines? From the word “machine,” we can guess that it is a type of equipment that helps reduce human labor. So today, we will explain the differences between fiber laser cutting machines and regular fiber cutting machines so that you can understand the working principles of each type of machine.
Types of Fiber Laser Cutting Machines and the Differences Between Each Type of Laser Cutting Machine
First, let’s understand how a laser cutting machine works. There are two main principles of laser cutting: First, the laser light source produces laser light by simultaneously passing carbon dioxide, helium, and nitrogen gas directly into a hollow cylinder. This is followed by electrical energy stimulation. The resulting laser light has high energy, a narrow frequency, and intensity, enabling it to cut objects quickly and precisely. Second, the laser cutting head is like a lens that compresses the laser light into a smaller size. It creates a beam of light of a specific wavelength to cut objects as desired. After cutting, the cutting head injects low-pressure gas to blow away all cutting debris, leaving no traces. This is why fiber laser cutting machines are different from other types of laser cutting machines, categorized by their light source.
- CO2 Laser Cutting Machine
The working principle of a CO2 laser cutting machine is that the light source of this type of laser is a CO2 lamp. Typically, the power is 30-180 watts with a wavelength of 10.6 uM (10600 nm). This light wavelength is invisible to the naked eye, eliminating the need for protective glasses. CO2 lasers are the most popular type of laser due to their versatility. However, they are most commonly used on non-metallic materials such as wood, paper, leather, plastic sheets, wallpaper, and acrylic sheets. They can also be used in the food industry. CO2 lasers can also cut metals such as steel, stainless steel, and aluminum. However, a high level of metal cutting expertise is required. - Diode Laser Cutting Machine
Diode laser cutting machines produce a light source from a very small diode, resulting in low power output. These machines typically have output powers ranging from 1 to 10 watts. The emitted light is in the UV range of 405 to 1080 nm, which is visible to the eye and appears as blue-violet light. Eye protection is required when using the laser. The laser’s compact size and low power output make it easy to control, making it ideal for high-precision work such as engraving. - Fiber Laser Cutting Machine
This type of fiber laser cutting machine has relatively higher power than other types of laser cutting machines. Its light source consists of multiple diode-lasers that concentrate light into a fiber strand and transmit it to the laser head through a small focus. It is commonly used for cutting metals, not non-metallic materials. However, the advantage of this type of laser cutting machine is its relatively high operating lifespan, exceeding 25,000 hours, resulting in stable and higher quality laser light output than CO2 laser cutting machines. This type of laser cutting machine is the most expensive compared to other types. - Nd:YAG or Nd:YVO Laser
The Nd:YAG laser, commonly known as the Gentle Yag laser, has two wavelengths: the first at 532 nm and the second at 1,064 nm. It is commonly used in the beauty industry as a skin conditioning technology that emit appropriate wavelengths. However, this type of laser can also be used to cut metals and non-metals, including plastic and acrylic sheets. It can also be used for welding. However, this type of laser is not commonly used for laser cutting due to its relatively high cost and lower operating hours than fiber laser cutting machines.
From all that has been said, it is clear that fiber laser cutting machines differ from the various types of laser cutting machines currently in use. The operating principles of all laser machines are quite similar: they use a laser beam to generate heat and pressure on the surface of an object, causing the object to melt and be cut apart into pieces with a smooth, beautiful surface with precision.
