What is a fiber laser cutting machine?

A machine that cuts metal with a laser beam is called a fiber laser cutting machine. A fiber laser, a kind of laser that sends laser light across a fiber optic cable, produces the laser beam. Fiber lasers are incredibly effective and can provide extremely powerful laser beams.

How do fiber laser cutting machines work?

Metal is vaporised when it is exposed to the laser beam. The metal is then expelled by a stream of gas, such as oxygen or nitrogen, once it has vaporised. The laser beam can quickly cut through metal because of its rapid movement.

Why do fiber laser cutting machine cut stainless steel so well?

Although stainless steel is an extremely durable material, it also reflects light very well. Due to this, cutting with conventional techniques like plasma cutting or waterjet cutting is challenging. Because the laser beam is absorbed by the metal, fiber laser cutting machines are excellent at cutting stainless steel.

Advantages of cutting stainless steel with a fiber laser machine

·           High precision: Fiber laser cutting machine can create very exact cuts. This is crucial for applications where the cut's accuracy is crucial, like the production of aeronautical or medical products.

·           Smooth cuts: Fiber laser cutting machine deliver clean, burr- and dross-free cuts. This improves the appearance of the cuts and lessens the need for post-processing.

·           Fast cutting speed: Steel may be quickly and efficiently cut with fiber laser cutting machines. When cutting huge amounts of material, this can save both time and money.

How to set up a fiber laser cutting machine for stainless steel cutting

You require the following in order to set up a fiber laser cutting machine to cut stainless steel:

If you are cutting stainless steel, choose the right laser power for the thickness. 

The thickness of the material will determine how much laser power is needed to cut stainless steel. In general, thicker materials require greater laser power to be sliced.It's important to keep in mind that these are only guiding principles.Depending on the particular type of stainless steel, the size of the laser cutting machine, and other factors, the actual laser power needed will differ. It is usually preferable to speak with the laser cutting machine's manufacturer to find the ideal laser power setting for your particular application.

Common Problems When Using Fiber Laser Cutting Machine

The most common problems when using a fiber laser cutting machine are:

• Poor cuts: These can be the result of employing the incorrect cutting speed or feed rate, excessive or insufficient laser power, or all three.

• Burrs: If the cutting speed is too slow or the cutting nozzle is not properly positioned, burrs may form on the cut's edges.

• Drossl: If the cutting gas is the wrong kind or the pressure is too low, drossl may form on the cut's edges.

• Slow cutting speed: If the laser power is too low or the cutting speed is too high, the cutting speed may be slow.

How to fix issues with a fiber laser cutting equipment while cutting stainless steel

1.Check the laser power setting. The amount of energy given to the material being sliced is known as the laser power. A low laser power will result in a rough or incomplete cut. The material may overheat and change if the laser strength is too high.

2.Check the cutting speed and feed rate. The speed at which the laser beam traverses the material is known as the cutting speed. The material moves under the laser beam at a certain pace, which is known as the feed rate. The cut may be imperfect or hard if it is made too quickly. Too slow of a cutting speed could cause the material to overheat and distort.

3.Check the cutting nozzle alignment. The component of the laser cutting device that directs the laser beam onto the material being cut is called the cutting nozzle. The laser beam may not be properly focused and the cut may be imperfect or rough if the cutting nozzle is not correctly positioned.

4.Check the cutting gas type and pressure. Molten material in the cutting area is removed with the use of the cutting gas. The quality of the cut can be impacted by the type and pressure of the cutting gas.

If you have looked into all possibilities and are still having trouble using a fiber laser cutting machine to cut stainless steel, you may need to seek help from the laser cutting machines manufacturer or a certified laser cutting expert.

Additional advice for troubleshooting issues with cutting stainless steel with a fiber laser cutter is provided below:

·         Maintain a clean laser cutting system. The laser beam may scatter and the cut may be uneven or incomplete if the laser cutting machine is filthy.

·         Regularly swap out the cutting nozzle. The laser beam can spread as a result of a worn cutting nozzle, resulting in an incomplete or sloppy cut.

·         Make use of the right kind of cutting gas. The kind of cutting gas used can impact the cut's quality.

·         Use the proper cutting gas pressure. The quality of the cut may be impacted by the cutting gas's pressure.

·         Monitor the cutting process. To make sure the cut looks good it's crucial to keep an eye on the cutting procedure. If the cut does not look good, change the laser's power, cutting speed, feed rate, cutting nozzle alignment, cutting gas type, or cutting gas pressure.
