Have a safe operation on fiber laser cutting machine-Teresa

Have a safe operation on fiber laser cutting machine

Have a safe operation on fiber laser cutting machine.

Nowadays fiber laser cutting machines are widely used in more and more industries. They can cut carbon steel, stainless steel, galvanized steel, aluminum, brass, etc. In this article, we will tell you how to have a safe operation of fiber laser cutting machine.

A fiber laser cutting machine.

Firstly,cutting accuracy:

Cutting accuracy is the basis for selecting a machine tool. It refers to the contour accuracy of the cutting workpiece, not the static accuracy marked on the sample!

The difference between a good machine and a poor machine is whether the accuracy of the high-speed cutting of the part will change, and whether the consistency of the workpiece will change greatly when cutting at different positions!

Secondly, cutting efficiency:

Cutting efficiency is an indicator of the profitability of a laser cutting machine. Cutting efficiency refers to the time when cutting workpiece, rather than simply looking at the cutting speed!

The higher the cutting efficiency, the higher the processing cost and the lower the running cost. It is a tool to make money!

Thirdly,Maintenance cost:

At present, the maintenance cost of the laser cutting machine is mainly from the maintenance cost of the laser!

However, the maintenance cost of each laser is different.

Fourthly, the service life:

The service life is an evaluation of the machine to save money, the longer the service life of the machine, the lower the depreciation expense of the laser cutting machine.

The main factors that determine the life of a machine tool are as follows:

The rigidity of the machine tool, simply speaking, the heavier the tonnage of the machine tool, the better the rigidity!

The configuration of the machine tool, as well as the brand and quality of the transmission device!

Carbon steel cutting by fiber laser cutting machine-Eliza

Carbon steel cutting by fiber laser cutting machine-Eliza

Carbon steel cutting by fiber laser cutting machine

For carbon steel cutting, generally, will burn the material. Possible reasons as below.

(1) The laser focus position is offset, and the focus position test is performed, and the offset is adjusted according to the offset of the laser focus.

(2) The output power of the laser is not enough. It is necessary to check whether the work of the laser generator is normal. If it is normal, observe whether the output value of the laser control button is correct, if it is not adjusted properly.

(3) The cutting line speed is too slow, and it is necessary to increase the line speed during operation control.

(4) The cutting gas is not pure enough to provide high quality cutting working gas

(5) The instability of the machine tool running time is too long. At this time, it needs to be shut down and restarted.

Laser not completely cut

The reason why the laser is not completely cut.

(1) The selection of the laser nozzle does not match the thickness of the processing plate, and the nozzle or processing plate is replaced.

(2) The laser cutting line speed is too fast, and the operation control is required to reduce the line speed.

Abnormal sparks when cutting low carbon steel.

When the low carbon steel is cut normally, the fire bouquet is long, flat, and has fewer splits. The occurrence of abnormal sparks will affect the smoothness and quality of the cut section of the work piece.

In this case, if other parameters are normal, the following should be considered.

Firstly,The laser head nozzle has serious loss, and the nozzle should be replaced in time.

Secondly, In the case of no new nozzle replacement, the working gas pressure should be increased.

Thirdly, If the thread at the joint between the nozzle and the laser head is loose, the cutting should be suspended immediately, check the connection state of the laser head, and re-thread the thread.

Finally,if you want to know some details,contact us.

And also,if for more questions just let us know.

Why is a fiber laser cutting machine in automotive Industry-Amber

Benefits of Laser Cutting in Automotive Industry

1. Clean and perfect cuts – no edge reworking necessary

2. No material fixation necessary

3. Extremely high level of repeat accuracy

4. Laser cutting and engraving in a single operation

5. No tool wear, therefore consistently high cut quality

6. High degree of flexibility in the choice of contours – without any need for tool construction or changeover

Advantages of Laser Cutting Machine in Automotive Industry

Putting its specific benefits and advantages aside for just one moment, cutting with a laser is one of the most used processes in the automobile industry, and any manufacturing industry for that matter. It involves the process of cutting materials and shapes down to size, and this is something that is widely use when it comes to creating intricate and complicated products.

However, laser cutting itself provides a unique alternative to other forms of traditional cutting that are on the market. Perhaps the biggest advantage is that users can deliver extremely precise finishes with smooth edges, heightening the end product and reducing material waste. Laser-based cutting also uses an extremely low power consumption, it has low maintenance costs, and can be used for multiple applications, reducing time wastage too.

Finally, it is one of the safest processes available. Laser cutting is required to be conducted in an enclosed, tight light box. Whereas more traditional and conventional methods see a free-running blade doing the cutting. While steps are taken to ensure that conventional methods are safe, laser cutting simply provides those in the manufacturing industry with one less thing to worry about.

Laser Cutting Steel/Laser Cutting Aluminum Problems – Elena

Although metal cutting operations traditionally employ mechanical or manual processes, laser cutting can be a viable, effective, and cost-efficient option for metal fabrication. Laser equipment is distinct from other cutting machines in both design and application. For example, laser cutters do not make direct contact with material, rely on high-energy power sources, have tighter cutting tolerances, and are generally automated to maximize precision.

Development of laser machine is very difficult. Unlike standard-grade or carbon steel, aluminum and stainless steel are light-reflective and heat-conductive metals. So it can be difficult to fabricate them using a laser cutting process. A possible solution for laser cut aluminum and laser cut steel, involves the use of a higher power setting coupled with compressed gas technology. Using gases in conjunction with cutting operations is fairly common. Nitrogen and oxygen assisted laser cutting machines can shape aluminum and stainless steel at relatively high capacities and with quality edge finishes. However, higher electricity consumption and the cost of peripheral equipment. Such as gas or air filters, can increase expenses for these systems.

Research and Development

Many organizations, such as the Laser Institute of America and Laserlab Europe. Conduct ongoing research to determine the best standard practices and optimal laser applications for a range of materials. Likewise, laser cutting head specifications are continually being revised and adjusted to improve the quality of laser piercing and the cleanness of laser cuts. As laser cutting systems continue to improve in their capacity, production rates, and cost-efficiency. More steel and aluminum laser cutting applications are likely to appear.
