Laser cutting is a non- contact process which uses a light beam to cut materials; this results in a high quality and defined product. Laser cutting machines essentially direct the light beam through a nozzle and onto the item that needs dividing.
The technique can be incredibly useful when it comes to dividing thick or durable materials and will leave you with smooth, clean lines. The most common use for this technology is in industrial manufacturing, but it is starting to be implemented in small businesses and by hobbyists.
Although many people have made use of laser cutting machines, very few know much about them. Keep reading to find out some interesting facts about a good laser cutting machine!
Many people think that laser cutting machines are a relatively new invention, but this is not the case. In fact, this technology is quite old; the technique has been in use since the 1950’s.
Interestingly, the first device of this nature was invented in the early 1950’s. However, it took until the 1970’s for the technology to become a reality for manufacturing.
The growth in popularity for the technique was slow and it took a few more decades before it became a popular choice.
Laser cutting machines are not a one size fits all type of device and the intensity of the light beam will have an impact on the divide it creates. In simple terms, the intensity of the light beam will determine the thickness that can be sliced.
This basically means that you will need a higher strength light beam if you wish to slice through a thick material. A low intensity beam will allow you to slice through thin sheets of metal, but not metal bars, for example.
You may be wondering how it’s possible to control the strength of a light beam, but they are actually measured in watts. Interestingly, the power is calculated as the total energy emitted in the form of light per second.
While this procedure is known for resulting in clean lines and accurate slices, the laser cutting machine itself, and the focal length of the light lens can impact the quality.
A lens with a short focal length will create a small dot size and short depth focus. This results in a lesser slice time and a more precise end result. However, it is important to consider the thickness of the item you wish to slice when deciding on the focal length. For thicker materials, a short focus will not suffice, therefore a longer light beam focal length is required.
One of the main concerns when it comes to utilizing technology is its environmental impact. Many inventions are bad for the environment or produce fumes that harm the atmosphere, this means that people want to find more environmentally friendly options.
This is not a concern with light beam technology, it is known for being one of the few environmentally friendly and sustainable methods of slicing materials. The process is quiet, efficient and restricts harmful fumes to a specified chamber that can be easily and safely ventilated.
It is also important to note that this process is exceptionally safe for the user. Operator safety is paramount and there are multiple fail safe checks built into the process.
Light beam technology is clearly not a new discovery, but it has been refined and developed over the years to make it more efficient. It is safe to say that this is not only one of the safest and most environmentally friendly options, but it also gives the best quality results.
