How Does Laser Cutting Focus Affect Burr Formation When Cutting Carbon Steel with Air?

One of the key advantages of using negative focus for air-assisted cutting is its ability to achieve high cutting speeds while maintaining a relatively low cost. This makes it an attractive option for businesses looking to improve their productivity and reduce production costs.

However, one drawback of using negative focus for air-assisted cutting is that it can result in a rough cross-section of the cut. This may not be suitable for applications that require smooth and clean edges, such as in the automotive or aerospace industries.

To address this issue, manufacturers are constantly exploring new technologies and techniques to improve the quality of the cuts produced by air-assisted cutting of carbon steel. One such technology is the fiber-cutting laser machine, which utilizes a high-powered laser to cut through carbon steel with precision and accuracy.

Fiber-cutting laser machines are capable of producing clean and precise cuts on carbon steel, making them ideal for applications that require high-quality finishes. These machines are also versatile and can be used for cutting a wide range of materials, making them a valuable asset for businesses in various industries.

In the world of fiber-cutting laser machines, one common issue that operators may encounter is the presence of burrs. These pesky burrs can affect the quality of the cut and may require adjustments to the focus of the laser beam.

There are two main types of burrs that can occur during the cutting process. The first type is a lying burr, which indicates that the focus of the laser beam is too low. In order to correct this issue, the focus setting should be adjusted upward. For example, if the original focus setting is at negative five, it may need to be adjusted to negative 4.5 or negative 4 to eliminate the lying burr.

On the other hand, a standing burr indicates that the focus of the laser beam is too high. To address this type of burr, the focus setting should be adjusted downward. For instance, if the original focus setting is at negative five, it may need to be adjusted to negative 5.5 or negative 6 to get rid of the standing burr.

It is important to note that there will always be some level of burrs present in air-assisted cutting processes. However, using oxygen during the cutting process can help minimize the formation of burrs. While it may not be possible to completely eliminate burrs, using oxygen can significantly reduce their occurrence.

Whether you are using a fiber laser tube cutting machine, a fiber laser pipe cutting machine, or a sheet metal fiber laser cutting machine, it is essential to pay attention to the presence of burrs. By making the necessary adjustments to the focus of the laser beam and utilizing oxygen during the cutting process, you can ensure cleaner and more precise cuts.

In conclusion, burrs are a common issue in fiber-cutting laser machines, but with the right adjustments and techniques, they can be effectively minimized. By understanding the causes of burrs and implementing the appropriate solutions, operators can achieve higher quality cuts and improve overall efficiency in their cutting processes.
