The structure and function of the laser cutting head

The cutting head of a laser cutting machine plays a crucial role in the precision and accuracy of the cutting process. Its main function is to focus the laser beam transmitted by the laser source to form a concentrated focal point for cutting various materials. This focal point is where the laser beam is at its most intense, allowing for efficient and precise cutting.

The cutting head consists of multiple sets of lenses that help in directing and focusing the laser beam. These lenses are carefully calibrated to ensure that the laser beam is focused accurately at the desired cutting point. The lenses also help in controlling the size and shape of the laser beam, which is essential for achieving clean and smooth cuts.

In addition to the lenses, the cutting head may also contain other components such as a nozzle for assisting in the removal of molten material during the cutting process. Some cutting heads also have sensors and cameras for monitoring the cutting process in real-time, allowing for adjustments to be made as needed to ensure optimal cutting results.

When it comes to laser cutting machines, China is a leading manufacturer with a wide range of options available. Fiber laser cutting machines are particularly popular for their high precision and speed. These machines use fiber optic technology to deliver a powerful laser beam that can cut through a variety of materials with ease.

If you are looking for a fiber laser cutting machine in China, there are many reputable manufacturers and suppliers to choose from. It is important to consider factors such as the cutting speed, power output, and cutting bed size when selecting a machine that meets your specific cutting needs.

When it comes to the price of laser cutting machines in China, there is a wide range of options available to suit different budgets. The cost of a machine can vary depending on factors such as the brand, cutting capabilities, and additional features. It is important to do thorough research and compare prices from different manufacturers to find a machine that offers the best value for your investment.

Details about Laser Cutting Head

1. Optical fiber line

The function is to protect the optical core. The bending diameter cannot be less than 200mm.

2. Optical core

It is the medium for laser transmission. The diameter of the optical core is very small, such as 30u, 50u, 100u, 150u, etc. 1mm=1000u 50u means that the laser is transmitted through a 0.05mm optical core

3. Upper protective mirror

Very thin. The main function is to prevent dust from entering the inside of the cutting head and protect the collimator

4. Collimator

The lens has a convex surface and produces refraction. When the laser passes through the collimator, it will amplify the laser. Most cutting heads change the focus by moving the collimator up and down through the internal motor (the collimator is very expensive and must be replaced in a dust-free box)

5. Focusing mirror

Gather the laser magnified by the collimator. A small part of the laser head changes the focus by moving the focusing mirror (replacement must be replaced in a dust-free box)

6. Middle protective lens

Protect the focusing mirror and act as a seal

7. Lower protective mirror

Prevent iron slag from returning upward during perforation and cutting, and isolate the cutting gas

8. Ceramic ring

A Protect the laser head from damage when it is hit

B Disperse the heat generated by the laser head during the cutting process

C The ceramic ring also transmits electrical signals

D The sealing ring and ceramic ring seal the gas inside the cutting head

9. Nozzle

The laser and cutting gas pass through the nozzle. The cutting quality and speed of different nozzles are different

10. Focus

The intersection point of the light after the focusing mirror is the point with the highest laser energy. Different focal points are used to cut different plates. Fiber laser is very sensitive to dust. Any problem with any lens will affect the cutting quality and speed
