Common Problems Of Fiber Laser Cutting Machine

Fiber laser cutting machine main use high temperature gasify metal material and blow the gas away under the help of inert gases. Compared with traditional cutting process, it have very high precision and fast cutting speed. At the same time, its loss rate is very low, so it have more and more wide application.

When use fiber laser cutting machine, also we will face many different problems, follows is some common problems and solution. It can help us use this machine better.

Burrs

Burrs are raised edges or pieces of material that may appear on a piece of sheet metal. Unfortunately, burrs are common when handling a laser cutting machine. Luckily, there are multiple ways metal fabrication workers can resolve this problem. Start by inspecting the focus of the laser. The focus point of the machine may need to be adjusted if burrs show up regularly. Another reason why burrs appear when using a laser cutting machine is that the power may not be high enough. Workers must adjust the power settings on the device to ensure it has enough strength to cut through metal without incidents. Finally, it’s important not to over to overload laser cutting equipment. If the feed rate is too high, the machine won’t be able to process it. Also, laser cutting devices need a break –

they shouldn’t be running for hours on end. Cut down the feed rate and turn off the machine when you aren’t using it to mitigate problems.

Incomplete Cuts

Another common problem that occurs with fiber laser cutting machines is incomplete cuts. An unfinished cut can occur because of a machine gas error. Laser cutting machines use compressed gases (either oxygen or nitrogen) to help cut through metal. If someone notices incomplete cuts on pieces of metal, they should check over the gas quality to ensure that it’s pure and free of contaminants. Incomplete cuts can also happen because the feed rate is too high while the power is too low. A worker who sees inadequate cuts in sheet metal should press pause on the device immediately until the problem is resolved.

Other common issues when handling laser cutting machines are materials discharging from above and lack of precision in the surface area. The solution to this fiber laser cutting problem is simple. Like the other problems previously discussed, workers should reduce the feed rate and increase the power in they encounter these issues. It’s also vital that people work with high-quality sheet metal. If you use rough sheet metal, you’re already starting off on a bad foot. Finally, metal fabrication shops should always buy top-of-the-line equipment. Anyone in need of a fiber laser tube cutting machine should look no further than Mac-Tech. Our machines will eliminate the need for extra sawing, drilling, and deburring. Mac-Tech ensures that your productivity will increase and the quality of the cut will improve.

Erosion on the sharp corners

When fiber laser cutting machine cut sharp corner, laser will turn to another side when finish one side. During this process, laser head will become ZERO then back to normal speed. Laser will stay on the corner parts for long time but laser power keep working. Due to the heat radiating area is very small near the corner so the corner temperature will be very high and metal will be melt. So the corners parts is not smooth.

Cutting process is discontinuous

For fiber laser cutting machine, discontinuous cutting is very common. Usually it will bring large waste for our work.

Unreasonably program is the most common reason to rise this problem. Metal fiber laser cutting need close to the cutting surface. When we cut many different parts on one plate, program select lineation first then cutting acquiescently. It can avoid laser cutting head crash the cut parts and broken laser cutting head. When we white the program if some position is not closed, laser cutting will be discontinuous. 

Also, change auxiliary gas during cutting process also may cause this problem. We know auxiliary gas will blow away the gasified metal, when we continue cutting the same parts after change gas, the position may be little different with finished position.

If you encounter other problems when using the laser cutter, you can communicate with our staff online, and our technicians will provide you with effective solutions in time.
