Understanding Laser Cutting Technology

LASER stands for Light Amplification by Stimulated Emission of Radiation.

A laser is an artificial light source generated by stimulated emission within an inverted energy state of a medium.

What is Laser Cutting Technology?

Laser cutting is a modern technology that uses highly focused laser beams to cut both metal and non-metal materials. The process is fully automated, operating according to pre-programmed machine settings.

It is regarded as one of today’s most advanced metal processing technologies today, applied across various industries, including mechanical engineering, medicine, defense, and manufacturing.

* Advantages of Laser Cutting Technology:

• Delivers precise, clean, and visually appealing results across diverse profiles and materials.
• CNC control systems offer features such as size adjustment, pausing, and acceleration, helping save time and simplify operations.
• Maximizes the use of raw materials with minimal waste.
• Suitable for producing diverse product types.
• Machines are equipped with laser shields, along with automatic dust extraction and filtration systems, ensuring a clean workspace and safeguarding operator health.

* Working Principle of a Laser Cutting Machine:

A power source generates a laser beam, which is directed to the cutting head. The head is fitted with a converging lens that focuses the beam, concentrating its energy on the workpiece fixed on the cutting table.

Depending on the material type and thickness, supporting gases such as oxygen or nitrogen are used during cutting. The controller manages the movement of the cutting head and the delivery of the laser beam. A cooling system is essential to dissipate heat and maintain stable operation during the process.

* Common Types of Laser Cutting Machines:

• CO₂ Laser Cutting Machines: Operate by using a flow of CO₂ gas stimulated by a power source to emit high-energy light. They are capable of cutting both metal and non-metal materials.
• Fiber Laser Cutting Machines: A more advanced and widely used technology today. They generate a high-power, high-density laser beam through optical fibers, which is then projected onto the material’s surface to melt and vaporize it. Fiber lasers are known for their precision, speed, particularly in cutting metals.
