Why Laser Cutting Machine Is Becoming Increasingly Popular in the Modern Sheet Metal Processing Market

What Is a Laser Cutting Machine?

Laser cutting is an advanced and widely used cutting process in current material processing. It is a thermal cutting method that uses a high-energy density laser beam as a "cutting tool" to cut materials. The high-power density laser beam irradiates the workpiece, causing the irradiated material to quickly reach the ignition point or melt and ablate. Simultaneously, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby completing the workpiece cutting. The CNClaser cutting machine has the advantages of precision manufacturing, irregular processing, flexible cutting, one-time forming, fast speed, and high efficiency. It has solved many problems that conventional methods cannot solve in industrial production. The emergence of laser cutting machine has epoch-making significance for industrial development.

Laser can cut most metal and non-metal materials. In the electrical manufacturing industry, it is mainly used for sheet metal switch cabinet processing; in the transportation machinery industry, it is mainly used for manufacturing conveying machinery, handling vehicles, and loading and unloading machinery; in the petrochemical industry, it is mainly used for cutting petroleum screen tubes; in the automotive manufacturing industry, it is mainly used for cutting complex-shaped car body sheets and various curved surface parts, including plane cutting and three-dimensional cutting; in the engineering machinery manufacturing industry, it is mainly used for processing mechanical structural parts; in the medical device industry, it is mainly used for manufacturing medical machinery, meeting requirements for precision, safety, and surface roughness of medical machinery; in the decoration industry, it is mainly used for cutting various decorations in public leisure places, such as hall wall decorations and advertising signs; in the packaging industry, it is mainly used for processing various shapes and sizes of packaging boxes.

Laser cutting machine hardware mainly consists of bed, beam, worktable, laser, cutting head, voltage stabilizer, water cooler, electric control cabinet, air source (oxygen, nitrogen, air). The system includes electrical system, mechanical system, gas circuit system, optical system, hydraulic system, lubrication system, and cooling system, which is an automated equipment integrating machine, optics, electricity, gas, and liquid. The processes used in the manufacturing of machine tools include bending, welding, machining, and assembly. The mechanical transmission structure includes ball screw nuts, gears and racks, and synchronous belts. The main mechanical transmission is gear and rack transmission because gear transmission is instantaneously precise, can handle heavy loads, and is efficient.

Why the Laser Cutting Machine Is Becoming Increasingly Popular in the Modern Sheet Metal Processing Market?

High precision

Laser cutting machine can provide very high cutting accuracy and detail. This makes them especially useful in applications where high precision and complex cuts are required, such as precision engineering.

Fast cutting speed

Laser cutting machine is usually faster than flame and plasma cutting machines. This means higher production efficiency, as more work can be completed in the same amount of time, increasing productivity.

Small heat-affected zone

The heat-affected zone of laser cutting is smaller than that of flame and plasma cutting, reducing the risk of material deformation and thermal damage. This is particularly important for precision machining and applications that need to maintain the mechanical properties of the material.

Environmentally friendly and safe

Laser cutting machine is usually more environmentally friendly than flame cutting and plasma cutting, producing less smoke and pollution. At the same time, there is no open flame in the laser cutting process, making it relatively safe.

Low post-processing requirements

Due to the high precision of laser cutting machine, the cutting edges are usually smoother and neater, reducing the need for subsequent processing and handling. This further saves time and costs.

Automation and intelligence

Modern laser cutting machine is usually integrated with advanced automation and control systems, allowing seamless integration with computer-aided design software, realizing intelligent production. This improves the efficiency and flexibility of the cutting process.

These advantages make laser cutting increasingly favored in the sheet metal processing market, gradually replacing traditional flame and plasma cutting.
