Steel Cutting

Cutting steel is the process of dividing single material sheet thorough its whole thickness. In usual cases desired cutting angle is simply orthogonal to the surface. Within the steel cutting technology main purposes to achieve are: narrow cutting slit, minimize consumption of energy, maximizing the quality of cut edges and limit heat influence over heating area as possible.

We can forge and split steel sheets by using different methods. All of them have their own advantages which makes every of them usable in various situations. It starts from simple, hand operated oxy burners to the highly automated plasma and laser cutting cnc machines which. With mobile oxy burner we can access to places which are not flat or simply shaped or difficult to access with heavy and big machines. CNC steel cutting machines are usually dedicated to precision print into the flat sheet projects prepared before on specialised software. Similarly to ink, laser printers or plotters which make possible for computer drawings to appear on paper, cnc steel cutting machines allow to create very complex details appear real in steel.
Ideal cutting process would allow to separate steel structure on atomic (covalent) bonds alongside given patch without any influence on physical features of cutted material. Steel cutting technology today doesn’t give perfect solution to those conditions and the huge step will be made when nanotechnology come into a game for real.

But also today we can achieve very well results (and usually good enough for most uses) in precision steel cutting by using modern and properly maintained machines or by combining various methods alltogether. As it is not a surprise, well maintanance and servicing is crucial in getting expected results.

Laser cutting features

For some certain reasons there are no perfect ways to machining so hard materials as steel and that’s why there are still many people on researching side. They are looking for more and more universal solutions and not to expensive at same time with high precision and accuracy. Flexibility and eventuality for setting up the whole kit to the individual purposes and preferences is very important value also. So we should have the knowledge about some limitations of technologies we choose to reach our goals. It is important if you are going to buy laser cutting machine for your purpose. Some promotional flayers are tend to avoid this kind of information, focusing on adventages only. Here are some important info for you:

in most cases, minimal radius of the the hole made by laser beam is equal to half of steel sheet thickness.
the quality (smoothness) of cutted edge for the final products (elements) in most cases when meagre sheets are machined. With the increasing thickness of steel sheets the edge can not be so smooths, and further processing can be required sometimes. It is caused by the laser beam power so if you are going to cut thicker material you need more power than declared “highest values” in machine specification manual.
the most of cutting machines doesn’t allow to set up laser beam axis so you can cut in the right angle only.

Laser Cutting Basics

Laser cutting of steel sheets can be applied to differend kinds of material like: rustless steel, acid-resisting steel and aluminum. Actually, cutting by laser is not limited to stell only – also wood and synthetic can be processed. The most important advance of cutting by laser is the highest quality of the final elements and ultimate precision of developed elements. They usually need no further processing and in most cases are ready to use right after taking out of the machine. And this si the crucial moment when it comes to setting the price.

Automated process of optimise cutting way can save the material in the way no other method can stand with. Average quality of edge cutted by the laser is very smooth and the accuracy is keep at 0,01 parts of the milimeter). Thanks to the computer driven laser beam patch the waste can be pressed to the minimum. Movements of the laser beam during the process are quick, which means very quick delivery time but also minimizes the termical influence on the material so it preserves natural steels features as much possible.
