What is the Advantage and Disadvantage of Single-platform Fiber Laser Cutting Machine

Laser cutters are high-energy, focused laser beams that cut sheets of steel, wood, plastic, and other materials into two-dimensional parts in the manufacturing and hobbyist arenas. "Laser" is a commonly used term for "Light Amplification by Stimulated Emission of Radiation," which explains the physical science necessary to generate laser light. It is a widely adopted technology suited for the mass production of precise two-dimensional parts.

The laser-cutting process utilizes a computer-generated program called a G-code, a set of machine-readable instructions instructing the machine where to move the laser-cutting head. Once the program is loaded, the material may require additional preparation before loading material onto the cutting bed. Once the material is loaded, a small, high-energy light beam is initiated and focused on one spot to heat the material and initiate the cutting process. As the material heats, the laser is directed to cut multiple parts using a series of mirrors and lenses. The intense heat melts and often vaporizes material as it is directed across the bed while cutting parts from the material sheet. Parts are removed and may be further processed.

Laser cutters are used in a range of applications, including engraving, laser welding, tube cutting, and sheet metal and plate cutting. There are several different types of lasers and methods used for Laser Cutting. These include the following:

Types of Laser Cutting:

• CO2 Lasers – This laser utilizes carbon dioxide (CO2), Helium (HE), and Nitrogen (N) to optimize the cutting process; Nitrogen help to amplify the energy while Helium helps to dissipate the remaining energy after the cut. These lasers are often used with metals plate but struggle with materials that have high reflectivity and thermal absorption.
• Fiber Lasers – Flexible fiber optic cables carry photons to produce the beam with the assistance of rare earth elements such as erbium, neodymium, thulium, or yttrium. Each element produces different wavelengths for varying applications. These lasers are best suited for cutting reflective materials like brass or gold and, due to the flexibility of the fiber cable, can be mounted to robotic arms. 
• Nd:YAG lasers – This powerful, high-density laser is often used for marking and etching. This laser utilizes a neodymium (Nd) doped yttrium aluminum garnet crystal (Y3Al5O12) which aids the photon acceleration to create a high-intensity beam. Nd:YVO lasers operate similarly with improved power stability, reduced heat, and greater laser intensity. 

Laser cutters are used to cut a wide range of materials. The most commonly cut materials are listed as follows:

Fiber laser cutting is slowly getting the recognition it deserves because it is a technologically advanced way of cutting the shaping different materials in the manufacturing industry. The machines are irreplaceable because of their several advantages, and they win over the old cutting methods, such as mechanical cutting, because of speed and accuracy restrictions.

Fiber metal laser cutting machine is far superior to traditional cutters because of their high precision and high-speed cutting. Other laser systems are included in the list of fiber laser cutters, such as the:

Why do people choose fiber laser cutting machines for their manufacturing units?

Fabrication and manufacturing industries rely on high precision works and production rates for business benefits. Fiber laser cutting machine manufacturers rely on the devices’ versatility, speed, and precision. Let’s see the main advantages of laser systems:

1. Accurate cutting: A super high solid intensity beam of laser light is used to penetrate the material, cut it, and shape it according to design. It’s an easy job cutting material into shapes with high positional precision. Cutting the material in a particular dimension with fine details and width can be managed; thus, intricate and detailed designing, including complex shapes, is possible. Fiber laser beam cutting can achieve high levels of precision and accuracy.

Fiber lasers shine a high-power focused beam of light on the material and melt it to achieve intricate and delicate cuts that are precise and accurate. The cutting is detailed and shapes the material as desired. Hence, it is used in electronics, medical, aerospace, and automobile industries.

2. High speed: Fiber laser cutters are known for their fast cutting speeds and accurate design. The production time is reduced significantly as opposed to traditional systems of cutting. High-intensity laser beams have high cutting speeds and help shape the material proficiently through melting and evaporation.

3. Save money and time: If the cutting speeds increase, the time taken to cut the work pieces reduces dramatically, and more shapes are produced, thus helping save time and money. Fiber lasers are energy-efficient, and help cut costs to a great extent because they consume less power. Moreover, the prices also cut down because of the lower maintenance requirements.

4. High production rate: The fast speed of the laser beam melts and evaporates the metal quickly and proficiently. Wasted material is blown away, and the shapes are left behind. The whole process is rapid and efficient, contributing to the production rate. Fiber lasers cut rapidly through various materials resulting in improved cutting efficiency and higher production rates. Fiber laser cutting is especially preferred in the industrial segments with high-volume production needs.

5. Non-Contact Cutting: A fiber laser cutting machine does not let the laser beam come in contact with the material and thus can be called a non-contact process. There is no damage or contamination because there is no physical touch; hence, the process suits sensitive and delicate materials.

6. Minimal Material Waste: The fiber lasers with high precision minimize material wastage because the narrow cutting kerf drastically reduces the material removed during cutting. This is another reason for sustained manufacturing and cost savings.

7. Versatility: Fiber lasers can cut through several metals and materials such as stainless steel, copper, brass, aluminium, wood, certain plastics, composites, etc., making them ideal for different applications of aerospace, aeronautical, locomotive, automotive, electronics, and other manufacturing industries. The high powered laser beam can smoothly slide into materials and metals of different thicknesses and densities, thus making it one of the good choices for the manufacturing and industrial fields.

8. Minimum thermal distortion: Multiple laser light beams are focussed at a particular point, and the surrounding area develops a heat-affected zone during the process. Laser cutters have minimal thermal distortion, and the material’s heat-affected zone is small. There is significantly less damage to the material, and thus the need for additional processing and extra finishing is minimal. The structural integrity of the cut or trimmed areas is preserved to a great extent.

9. Low maintenance and reduced downtime: The Fiber laser machines are more or less stationary with some selective parts that move compared to other cutting methods. This is a positive factor because repairs are reduced, and maintenance is unnecessary, improving productivity and reducing downtime. Well, you may have to pay extra initially, but in the long run, these gadgets are a feasible investment.

10. Reduction in operational costs: The operating costs are lesser; thus, the expenses are reduced. These gadgets consume lesser power and have higher energy efficiency. This is why various manufacturers and industries prefer to get fiber laser cutters for their business facilities. The limited maintenance demands and cutting costs are excellent financing solutions for the manufacturing sector.
