Sheet Metal Fiber Laser Cutting Machine Maintenance Tips

Sheet metal fiber laser cutting machine are essential pieces of equipment that every shop should have. These devices help metal fabrication shops be more productive. These laser devices can perform functions that no one could possibly do on their own. However, major repairs create severe headaches in the future. Significant fixes take a lot of time to fix. This means the equipment is powered off, and production stops. If you want to keep your establishment running smoothly, you must perform preventative maintenance on these machines, so it is important to know how to maintain a fiber laser cutting machine.

As we all know that the  sheet metal  fiber laser cutting machine price is expensive. If you want to prolong the service life of the CNC fiber laser cutter, the machine daily maintenance is very important. Below I will introduce the daily maintenance and precautions of the fiber laser cutting machine for sale. Paying attention to the following matters can ensure the stable performance of the fiber laser cutter machine.

Sheet Metal Fiber Laser Cutting Machine Maintenance Tips

1. Cooling system maintenance

First, the water inside the water cooler needs to be replaced regularly, and the general replacement frequency is one week. The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water or distilled water and keep the water temperature below 35°C.

Second, keep the water flowing at all times. The cooling water is responsible for taking away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20℃ water temperature is better); when the water is cut off, the tube end will burst due to the heat in the laser cavity and even damage the laser power supply . Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, and the water pump fails, it must be repaired in time to avoid power drop or even equipment damage.

2、The cleaning of the lens
It is recommended to clean before work every day, and the equipment must be turned off.

There are 3 mirrors and 1 focusing mirror on the laser cutting machine (No. 1 mirror is located at the emission exit of the laser tube, which is the upper left corner of the machine, No. 2 mirror is located at the left end of the beam, and No. 3 mirror is located at the laser head fixed At the top of the part, the focusing lens is located in the adjustable lens barrel at the lower part of the laser head. The laser light is reflected and focused by these lenses and emitted from the laser head. The lens is easily stained with dust or other contaminants, which can cause laser loss or damage to the lens.

3. Maintenance of dust removal system

After the Laser machine has been working for a period of time, a layer of ash will be stuck on the surface of the lens due to the working environment, thereby reducing the reflectivity of the reflective lens and the light transmittance of the lens, and ultimately affecting the working power of the laser. At this time, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens should be wiped gently, and the surface coating should not be damaged; the wiping process should be handled gently to prevent falling;

4. Drive system maintenance

The environment of the workshop should be kept dry and well ventilated, and the ambient temperature should be between 4°C and 33°C. In summer, prevent condensation on the equipment, and prevent freezing of the sheet metal fiber laser cutting machine in winter.

Functionality of a sheet metal fiber laser cutting machine

Most laser cutting systems are operated by Computer Numerical Control (CNC) parameters. These computer controls enable high levels of precision and increased cutting speed. Once images or designs are programmed into the laser cutter, designs, shapes, and sizes can be altered, adjusted and tweaked with the punch of a button. The laser performs fast cutting actions with high accuracy, and a feature of CNC programming is regulating power output, meaning less energy while cutting is used. This enables the laser to adjust settings automatically during cutting depending on the thickness of the metal. Because of CNC programming, no tooling changes are necessary to make adjustments to the cut.

Savings on material costs are another benefit of laser cutting. Using a laser to cut images saves on material scrap, as the accuracy and precision of the laser beam does not require a border on either side of a cut. Also, two images or patterns can share a cut line, further reducing scrap. Other ways to save on scrap relate to cutting techniques such as nesting, lead-ins and lead-outs and tabbing on a laser.

Factors That Affect Laser Cutting Accuracy
Though laser cutting is considered the most accurate form of sheet metal cutting, it can’t achieve high accuracy without addressing a few requirements first. The following factors need to be taken into account when using a laser cutter:

Material type: The type of material you use the laser cutter on affects its precision or accuracy. In general, the smoother or thinner the material, the more accurate the cut. If you use the same settings for a different material, there will be differences in the accuracy. Use appropriate machine settings for each type of material and material composition.

Laser beam spot size: The smaller the spot size of the laser beam, the smaller, more precise the cut will be. Wider spot sizes result in less accurate laser cuts.

Laser power level: Different intensity levels cut through different materials in a more or less precise manner. Generally, thicker materials need a more powerful laser beam setting to evenly and accurately slice through the material.

Workbench accuracy: The workpiece material positioned on the workbench also has to be extremely precise for the laser beam’s cut locations to be accurate, as well. If the workbench is not flat or stabilized, the vibration will cause the process to lose accuracy.

To work with a laser cutting machine, you’ll need to get familiar with its settings and capabilities. Always take into account your material and workpiece stability, as well as the laser’s power level and spot size.

Fiber laser cutting machines are widely used for various industrial applications. Following are the features of these machines which make these machines so popular.

Fiber lasers have higher wall-plug efficiency as compared to other laser cutting machines.
These machines give the advantage of maintenance-free operation.
These machines have the special feature of easy ‘plug and play ‘design.
Moreover, they are extremely compact and hence very easy to install.
Fiber lasers are known as the phenomenal BPP where BPP stands for beam parameter product. They also provide steady BPP over the whole power range.
These machines are known to possess high photon conversion efficiency.
There is higher flexibility of beam delivery in case of fiber lasers as compared to other laser cutting machines.
These machines allow the processing of highly reflective materials too.
They provide lower cost of ownership.

The laser cutting machine is mainly used for laser processing machines that cut sheets into workpieces of the desired shape. A device that uses the thermal energy of a laser beam to achieve cutting. Laser cutting is the energy released when the laser beam is irradiated onto the surface of the workpiece to melt and evaporate the workpiece for cutting and engraving.A metal sheet laser cutting machine can not only meet the cutting requirements of customers for flat plates, but also meet the cutting of tube round and foreign materials (square steel, flat iron, channel steel, square tube). Steel, stainless steel, aluminum, alloy steel, aluminum alloy, carbon steel, stainless steel, copper, silver, gold, titanium, and other metal pipe cutting, square tube cutting, three-dimensional cutting.

Working principle of fiber laser cutting machine:

The cutting principle of the fiber laser cutting machine is that by outputting a laser beam with high energy density and focusing on the surface of the workpiece, the area irradiated by the ultra-fine focus on the workpiece is instantly melted and vaporized. The automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system. Fast speed and high precision, is one of the most advanced processing technology.When you understand the introduction of the metal pipe & sheet laser cutting machine above, and you want to buy it, you can find out about our company’s products.
