Main Configurations of Laser Sheet Metal Cutting Machine！

Laser sheet metal cutting machines have revolutionized the manufacturing industry, particularly in the cutting of sheet metals. Their precision, speed and versatility make them indispensable in various sectors, from automotive production to aerospace. 

1. Lasers

The lasers is the hardcore parts of laser sheet metal cutting machine. It generates the laser beam to cut through the material. The two most common types are CO2 lasers and optical fiber lasers. CO2 lasers is ideal for cutting non-metallic materials and the thicker sheet metal, while optical fiber lasers is known for their efficiency in cutting thin metal and high-reflective materials like aluminum and copper.

2. Laser Cutting Head

The cutting head focuses laser beam onto the sheet metal. It typically includes a nozzle, focusing lens, and sometimes a height sensor. The nozzle directs assist gases (like oxygen, nitrogen, or air) onto the cutting area, which helps in cutting and removing molten material. The focusing lens can adjust the beam’s focal point for precision cutting, while the height sensor maintains the optimal distance between nozzle and sheet metal.

3. Control System

The control system is the brain of the machine, managing the movement of laser cutting head and sheet metal. Modern sheet metal laser cutters are equipped with CNC (computer numerical control) systems that provide high accuracy and repeatability. The control system allows operators to input cutting patterns and parameters to ensure cutting precision and efficiency.

4. Platform (s)

The platform holds and moves the workpiece during cutting. There are different types of platforms, including flatbed and rotary tables. A high-quality platform can ensure high stability and precision. For the former, there are single and double exchange platforms that can synchronize cutting with loading & unloading. Less time for waiting and higher work efficiency since then.

5. Drive System

The drive system is to move laser cutting head or sheet metal. It can be a gantry system, where the cutting head moves over a stationary workpiece, or a flying optics system, and where the sheet metal moves while laser cutting head remains stationary. The choice of drive system affects the machine’s speed and accuracy.

6. Cooling System

Laser cutting usually gives rise to a significant amount of heat, which needs to be dissipated to prevent damage to the lasers and other core components. Cooling systems, typically water-cooled, are essential for maintaining optimal operating temperature and ensuring the longevity of the whole machine.

7. Assist Gas Supply

Assist gases, such as oxygen, nitrogen and air, play a crucial role during cutting. They help in cutting, remove molten material and cool off the cutting area. The type and pressure of the assist gas used depend on the material being cut and the desired cutting quality.
