Laser cutting in metal fabrication provides a large of benefits that traditional methods can not.
The precision accuracy means higher quality finishes and assemblies and the computer-generated rendering means that almost any job can be completed – regardless of the complexity.
It also delivers massive time efficiencies as well, compared to traditional, manual methods, there is less waste produced and less energy is required to complete projects. Additionally, this technique is also a lot more productive and precise than plasma cutting methods, making it the leading technology for metalwork.
Overall laser cutting is an extremely effective way to cut, manipulate and fabricate almost any type of metal and this technology has been readily adopted by KNS Metals across the board.
So how exactly does it all work?
It all starts with a computer
CNC (Computer Numerically Controlled) computers are programmed with the exact specifications for the job. This numerical control is the same technology used in 3D printing, taking control of the machining tools through microchips embedded in them. Essentially, it is capable of operating a variety of tools and delivers extremely precise results while reducing instances of human error.
How the technology works
The laser itself is made up of a very intense beam of light that is extremely narrow and often invisible to the eye because it is infrared. It can be highly focused by using a series of mirrors before the final beam goes through a nozzle to the precise point on the steel plate.
Other cutters can melt the metal and use gasses like oxygen or nitrogen to blow away the molten parts, but CNC lasers separate the parts directly out of the plate. This means higher quality edging and less risk of any burning, charring or discolouration from occurring.
The precision of a cut in metalwork is measured by kerf widths, which is the width of material that is removed during the process. The smaller this measurement is, the more precise the cut and the less waste is produced. For a half-inch slab of steel, a plasma kerf width would be around 0.15 inches, while a laser-cut would be 0.025 inches.
Less maintenance, greater safety
The accuracy and precision of the CNC laser cutter mean that the final projects are always going to be delivered to exact specification without any imperfections, jagged edges or discolouration.
But there are other major benefits as well. These machines require much less maintenance than other metalworking procedures and will deliver perfect results over a long period of time. And by moving the operator away from the cutting surface itself, it means there is far less risk of accidents or workplace injuries occurring.
KNS Metals prides itself on its safety standards but sometimes incidents happen that are out of our control. By using CNC techniques, we are able to dramatically improve our safety operations while delivering quality products for all of our customers.
