Cutting is the simplest and extensively used method in the field of metal fabrication. The laser cutting process is considered to be the most popular method for these jobs in the business due to its numerous advantages over other techniques.
But there are certain disadvantages, too. Let’s look at those wonderful benefits and disadvantages.
What are the benefits in Laser Cutting?
The reason engineers opt for a laser cutting service is with the many advantages it provides. The benefits of laser cutting include flexibility, precision as well as speed, repeatability and cost-effectiveness. It also offers great quality and contactless cutting, as well as versatility and automation options.
Laser cutting doesn’t require the use of different tools for each cut. The same set-up is ideal to cut a variety of different shapes in the same thickness. In addition, the intricate cuts don’t pose any issues.
Accuracy is among the main benefits of using lasers as compared to other cutting techniques.
A precision of +/-0.1 millimeters allows you to achieve high-precision without the need for any additional treatment. In the majority of cases the high precision implies that no additional tolerances are needed.
++/+/- 0.05 millimeters ensures that parts are basically identical to the other.
Laser cutting is faster than conventional mechanical cutting techniques. Particularly when it comes to more complicated cuts.
In comparison to other methods of thermal cutting, such as flame cutting or plasma cutting laser is faster up to a certain thickness , which is approximately 10 millimeters. The specific advantage boils down to the strength that the laser cutting tool but.
The work requires little human effort since modern laser cutting equipment is extremely automated. A skilled machine operator is a major factor in the final product, but it is faster to cut as well as the demand for manual labor results in lower cost when compared with other cutting methods.
Some machines come with feeding systems and follow-up conveyors. Of course, these configurations result in a more expensive Laser cutting machines.
With the proper configuration, laser cutters will only leave a tiny burr. In most cases, it’s not required to take it off. Of course , it is contingent on the substance thickness, the thickness and other aspects.
Another advantage is that you have a smaller HAZ. Because the microstructure in the HAZ changes and shrinks, a smaller HAZ area will result in better-performing and reliable components.
When laser cutting is used laser cutting, the beam is the only thing that gets into contact with the surface. This means that there isn’t any mechanical friction which could cause wear on tools.
This is perhaps one of the most significant advantages of laser cutting’s excellence. The flexibility manifests itself by two methods.
Laser cutting can be used with many different materials. There are a variety of metals, acrylics, MDF, wood, paper, etc. A machine can be set up to accomplish different tasks. However, of course the capability to cut these material is dependent on the strength of the machine.
A lot of laser cutters aren’t used for cutting just. Laser marking is a different way to make use of these machines. It has a variety of potential applications in the production of regular items.
A conventional laser cutting head is not able to be used to weld and an laser welding head is not able to provide the cutting speed and the quality required for cutting. Some machines allow the swapping of heads in case a different operation is required to be performed and combi-heads are being developed , however they aren’t ready to go public because of the various limitations they face.
In addition this technology can be used for various types of. Tube laser cutting can be used to carry out the procedure on any type of profile, from boxes up to channels that are open.
What are the disadvantages in Laser Cutting?
While laser cutting is utilized to make parts for almost all industries Laser cutting has its drawbacks. For instance, the requirement for experience, limitations on the thickness of metal, cost and harmful fumes are all aspects you should consider prior to deciding on laser cutting.
The need for expertise
As we’ve already mentioned that a skilled operator is required for making the maximum use of a laser cutter’s abilities. The proper set-up will ensure that the quality of cutting is at the level the public is expecting from this type of technology.
Limits to Thickness of Metal
In comparison to other methods of thermal cutting laser cutting is not suited for cutting very thick plates. The most suitable thickness is contingent on the machinery available and the knowledge available. In the average metal fabrication firms tend to laser cut their metal as thin as 15 or 20 millimeters.
One of the benefits that laser cutting has is its ability to cut various materials. In addition the process of cutting with thermal energy causes the material to melt, resulting in the emission of gases and hazardous fumes.
This is particularly relevant in the case of cutting through plastic. So a well-designed, but frequently expensive ventilation system is a necessity for a safe work setting.
