Exploring Ultra-Efficient Laser Cutting Technology


In the current processing industry, laser cutting machines have become a staple for various applications. Their efficiency and flexibility address challenges posed by traditional CNC punch machines. Laser cutting machines offer a non-contact processing solution, showcasing remarkable features such as minimal mechanical stress and deformation, straightforward operation, high cutting accuracy, and a small heat-affected zone.

Laser cutting stands out as the paramount application technology in the laser processing industry, constituting over 70% of the entire sector. Globally recognized as the most advanced cutting technology, laser cutting boasts precision manufacturing, flexible cutting, specialized shaping, one-time molding, high-speed operations, and unparalleled efficiency. It effectively tackles industrial production challenges that conventional methods struggle to resolve. Laser technology enables the cutting of a wide range of metallic and non-metallic materials.

1.What is Laser Cutting

Laser cutting, a revolutionary technology in the realm of manufacturing, harnesses the power of high-energy density laser beams to achieve precision and efficiency in cutting various materials. The process involves heating the workpiece with a concentrated laser beam, rapidly elevating the temperature to the material’s boiling point within an extremely short timeframe. As a result, the material vaporizes, creating a clean and precise cut.

Materials such as stainless steel with a thickness below 4mm find efficient application in laser cutting devices. For thicker materials like 20mm carbon steel, laser cutting with oxygen assistance is employed, albeit with the side effect of forming a thin oxide layer on the cut surface.

One notable advantage of laser cutting is the absence of tooling costs. This makes laser cutting equipment suitable for the production of small-batch components of various sizes that were previously challenging to process using traditional methods.

Typically equipped with Computer Numerical Control (CNC) systems, laser cutting devices receive cutting data from Computer-Aided Design (CAD) workstations through telecommunication lines.

The fundamental principle of laser cutting involves the focused, high-power density laser beam illuminating the workpiece, causing rapid melting, vaporization, ablation, or reaching the ignition point of the material. Simultaneously, a high-speed airflow, coaxial with the beam, blows away the melted material, facilitating the cutting process. Laser cutting stands as one of the thermal cutting methods.

2.Advantages of Ultra-Efficient Laser Cutting

A. Increased Precision

One of the standout advantages of ultra-efficient laser cutting lies in its ability to deliver unparalleled precision. As the laser beam is meticulously controlled through Computer Numerical Control (CNC) systems, it ensures that cuts are made with microscopic accuracy. This precision is especially crucial in industries where intricate designs and tight tolerances are non-negotiable.

B. Enhanced Speed and Throughput

Ultra-efficient laser cutting is synonymous with remarkable speed and throughput. The process of laser cutting allows for swift and seamless material processing, significantly reducing production time. This increased efficiency translates into higher throughput, making it an ideal choice for manufacturers aiming to optimize their production workflows without compromising on quality.

C. Material Versatility

The versatility of ultra-efficient laser cutting is a game-changer in the manufacturing landscape. Laser cutting can be categorized into four types: laser vaporization cutting, laser melting and cutting, laser oxygen cutting, and laser marking and control fracture.

1. Laser Vaporization Cutting: This method involves rapidly heating the workpiece with a high-energy-density laser beam, causing the material to vaporize. Laser vaporization cutting is ideal for extremely thin metals and non-metals like paper, fabric, wood, plastic, and rubber.

2. Laser Melting and Cutting: In this approach, the laser heats the metal material to melting point, and a non-oxidizing gas is ejected through a coaxial nozzle, expelling the liquid metal under strong pressure to form the cut. It is particularly useful for cutting materials resistant to oxidation, such as stainless steel, titanium, aluminum, and their alloys.

3. Laser Oxygen Cutting: Similar to oxy-fuel cutting, laser oxygen cutting employs laser as the preheating heat source and reactive gases like oxygen for cutting. This method is efficient for easily oxidizable metals like carbon steel, titanium steel, and heat-treated steel, offering faster cutting speeds compared to vaporization and melting cutting.

4. Laser Marking and Control Fracture: Laser marking involves scanning the surface of brittle materials with a high-energy-density laser, creating small grooves. Applied pressure then induces controlled fractures along these grooves. This technique is often used for materials like glass.

3.Types of Laser Cutting

Laser cutting technology encompasses various methods, each tailored to specific materials and applications. Here are the primary types of laser cutting techniques:

1. Laser Vaporization Cutting

In laser vaporization cutting, a high-energy-density laser beam rapidly heats the workpiece, elevating the temperature to the material’s boiling point in an extremely short timeframe. This process results in the formation of vapor, which forcefully exits the material, creating a cut. Laser vaporization cutting is particularly effective for thin metals and non-metals such as paper, fabric, wood, plastic, and rubber. Due to the substantial heat of vaporization, this method requires significant power and power density.

2. Laser Melting and Cutting

In laser melting and cutting, the laser heats the metal material to the point of melting. Subsequently, a non-oxidizing gas (e.g., Ar, He, N) is jetted through a coaxial nozzle, expelling the liquid metal under pressure to create the cut. This method is advantageous as it doesn’t require complete vaporization of the metal, reducing the energy needed to one-tenth of that in vaporization cutting. Laser melting and cutting find applications in materials resistant to oxidation, such as stainless steel, titanium, aluminum, and their alloys.

3. Laser Oxygen Cutting

Similar to oxy-fuel cutting, laser oxygen cutting uses laser as the preheating heat source and reactive gases like oxygen for cutting. The process involves a reaction between the incoming gas and the metal, causing oxidation and releasing a substantial amount of heat. Simultaneously, molten oxides and metal are blown out of the reaction zone, forming a cut in the metal. Laser oxygen cutting requires only half the energy compared to melting cutting, resulting in significantly faster cutting speeds. This method is suitable for easily oxidizable metals like carbon steel, titanium steel, and heat-treated steel.

4. Laser Marking and Control Fracture

Lastly, laser cutting includes the techniques of laser marking and control fracture. Laser marking involves using a high-energy-density laser to scan the surface of brittle materials, creating small grooves. Applying pressure then induces controlled fractures along these grooves. This method is often employed for materials like glass. Fracture control utilizes the steep temperature distribution produced by laser engraving to induce local thermal stress in brittle materials, causing them to fracture along predefined paths.
