Date:2024-09-25 09:40
In the advanced field of modern manufacturing, laser cutting technology has become an indispensable processing method in many industries due to its significant advantages such as high precision and flexibility. This article will delve into the process characteristics, main types, and wide range of application fields of laser cutting, providing a comprehensive analysis of the charm of this modern manufacturing technology.

I. Overview of Laser Cutting Process

Laser cutting is a high-precision CNC thermal processing technology that uses a high-power laser beam to cut, melt, or burn material sheets. It is applicable to various material types, such as metals, wood, and polymers, demonstrating strong versatility.

Compared with traditional processing techniques, laser cutting has unique advantages in sheet metal processing. It does not require custom tools and can easily handle the processing requirements of various complex shapes, making it particularly suitable for one-off jobs and low-to-medium volume production. During the processing, laser cutting can achieve extremely high precision, providing a strong guarantee for the production of high-quality components. However, laser cutting is not without its flaws. It may face some difficulties when processing materials thicker than 100mm, and its high energy consumption leads to relatively high operating costs, which also need to be considered in practical applications.

II. Main Types of Laser Cutters

(I) CO2 Gas Cutter

The CO2 gas cutter works by means of electric discharge pumping, and the laser it uses is mainly composed of carbon dioxide, helium, and nitrogen. This type of cutter has strong penetration ability and can pierce thicker materials than fiber cutters. It performs well in terms of processing efficiency and cost, and is therefore widely used in the manufacturing industry. For example, in the automotive manufacturing industry, CO2 gas cutters are often used to cut body panels, which can quickly and accurately complete cutting tasks of various shapes, improving production efficiency and product quality.

(II) Crystal Laser Cutter

The crystal laser cutter generates beams from YVO or YAG crystals, and it can cut stronger and thicker materials than CO2 cutters. It has unique advantages in some fields with high requirements for material cutting strength. However, the crystal laser cutter also has some disadvantages, such as relatively fast wear of machine parts, resulting in higher operating costs. Therefore, in practical applications, it is necessary to comprehensively consider whether to choose a crystal laser cutter based on specific production needs and cost budgets.

(III) Fiber Laser Cutter

The fiber laser cutter belongs to the family of solid-state lasers and uses glass fibers to amplify the base seed lasers. Compared with other types of cutters, the fiber laser cutter has many advantages, such as significant energy-saving effects, being 3 times more energy-efficient than gas cutters; relatively lower machine price and easier maintenance; and the ability to cut reflective materials, broadening its application range. In the electronic manufacturing industry, fiber laser cutters are often used to cut precision circuit boards. Its high precision and good adaptability to reflective materials can ensure the quality and performance of circuit boards.

III. Application Fields of Laser Cutting

Laser cutting technology has been widely used in many fields due to its excellent performance.

In the metal processing field, laser cutting can be used for a variety of metals, such as steel, aluminum, and copper. Among them, steel is a relatively suitable metal for laser cutting, while aluminum and copper may cause warping due to their reflection of light and thermal energy, but effective cutting can still be achieved through reasonable process adjustments and parameter settings. For example, in the aerospace field, laser cutting is often used to process high-strength metal components, such as aircraft engine blades and fuselage frames. Its high precision and flexibility can meet the strict requirements for quality and precision of aerospace components.

In the construction industry, laser cutting can be used to produce various architectural decoration components, such as metal curtain walls and carved railings. Through laser cutting, complex patterns and shapes can be designed and fabricated, adding unique artistic charm to the building. At the same time, the high precision of laser cutting can also ensure the installation accuracy of building components, improving the overall quality and stability of the building.

In addition, laser cutting also plays an important role in the advertising production, furniture manufacturing, and other industries. In advertising production, it can be used to cut various advertising signs and display racks to achieve personalized design and production; in furniture manufacturing, it can be used to cut sheets to create various exquisite furniture shapes, meeting the consumers' needs for the aesthetics and practicality of furniture.

In conclusion, as an advanced manufacturing technology, laser cutting technology injects strong power into the development of modern manufacturing with its unique process characteristics, diverse types, and wide range of application fields. With the continuous progress and innovation of technology, it is believed that laser cutting technology will play an even more important role in future industrial production, creating more high-quality and high-precision products for us.
