We are deeply aware of the importance of fiber laser cutting machines in modern manufacturing, and in fiber laser cutting technology, the cutting head is one of the key components that determine cutting quality, efficiency and material suitability.

Type of cutting head

Fiber laser cutting machines are typically equipped with two main types of cutting heads:

Focus lens: The focus lens is a key component used to focus the laser beam. It achieves highly precise cutting by focusing the laser beam on a single point on the work surface. The choice of focus lens depends on the nature of the cutting task, including material type and thickness.

Atomizing lens: The atomizing lens is usually located behind the focus lens and is used to protect the cutting head from material spatter and smoke. This helps maintain the quality of the cut and extends the life of the cutting head.

Cutting quality control

The design and quality of the cutting head directly affect the cutting quality. High quality cutting heads provide the following advantages:

More precise cutting: A high-quality cutting head ensures the stability and accuracy of the laser beam during the cutting process, resulting in a more precise cutting edge.

Smooth cutting edges: The superior design of the cutting head reduces burrs and blemishes during cutting, resulting in a smoother cutting edge.

Reduce welds: Welds are usually imperfect joints created during cutting. High quality cutting heads help reduce weld formation.

Focal length adjustment

Fiber laser cutting machines usually allow users to adjust the focal length of the cutting head according to different cutting tasks. Focal length refers to the distance between the focal lens and the working surface. Different focal length positions are used for cutting with different materials and thicknesses. This adjustment capability enables the operator to achieve optimal cutting results.

Cutting head protection

The cutting head is usually equipped with a protective cover to protect the cutting head from material sputtering or smoke damage. These protective covers protect the optical components of the cutting head, ensuring that they remain clean and stable during the cutting process. Maintaining and replacing the protective cover is part of maintaining the performance of the cutting head.

Automatic adjustment system

Some advanced fiber laser cutting machines are equipped with automatic adjustment systems that automatically adjust the parameters of the cutting head according to different cutting tasks. This includes automatic adjustment of focal length to ensure optimal focus position is maintained in cuts of different materials and thicknesses. This automation increases the ease of operation and helps to optimize the cutting results.

Material adaptability

The choice of cutting head is closely related to the cutting material. Different types of cutting heads are suitable for different types of materials. Therefore, when dealing with different materials, it may be necessary to change the cutting head to achieve the best cutting results. This requires the operator to understand the properties of the material and the suitability of the cutting head.

Maintenance and replacement

Regular maintenance and timely replacement are the key to maintaining the performance of the cutting head. The operator should regularly check the status of the cutting head, clean the optics, replace worn parts, and ensure the integrity of the protective cover. This will help extend the life of the cutting head and maintain the quality of the cut.
