Laser cutting is just one of many different processes that our high-quality fiber lasers are capable of. While one of our machines is capable of performing multiple processes for varying applications and materials, in this article we explore the laser cutting functionalities of our machines in greater detail.
This is the process of cutting a material down using a laser, which differs from more conventional methods that traditionally use a blade. While bladed cutting is still an approach that is used, cutting with a laser allows for much more precise and clean cuts, reducing material wastage and allowing components and products to be even smaller.
Using a laser cutting machine can help to deliver cuts with perfect finishes
There are three main types and techniques of cutting with lasers and associated machines:
Gas laser cutting machines, using C02 gas, is commonly used, but with a wavelength of 10.6 micrometres, it is only useful for non-metals.
Crystal lasers, is conducted using nd:YAG (neodymium-doped yttrium aluminium garnet) or nd:YVO (neodymium-doped yttrium ortho-vanadate) laser cutting machines. This process is similar to the fiber process, and with a wavelength of 1.064 micrometres, can be used on both metals and non-metals.
These lasers cut with a process where the core component used is an optical fiber, typically doped with rare elements such as erbium, thulium and dysprosium. Fiber laser machines have the same wavelength of that as a crystal laser cutting machine, 1.064 micrometres, and so can work with both metals and non-metals.
Here at SPI Lasers, we have opted for fiber laser based cutting. While it may not be the most common of the laser processes, we believe that it is by far the most versatile and beneficial.
We immediately ruled out gas cutting due to its inability to work with metals, as this limits its usage in a huge majority of the world’s industries. And while crystal lasers and fiber lasers bear striking similarities, fiber lasers proves to be the more useful and long-lasting cutting process.
This is because crystal laser machines typically have a service life of between 8,000 and 15,000 hours of use, while fiber lasers can last for around 25,000 hours. Alongside this, the replacement parts for fiber-based machines are much cheaper than the expensive parts for the crystal lasers .
We have two types of fiber lasers on offer:
A continuous wave fiber laser delivers a constant flow of energy over the material that you are cutting. We have a range of continuous wave lasers, with capabilities ranging from 100W to 6kW.
The continuous wave models that we stock at SPI Lasers are:
Depending on your requirements, different lasers will be more suitable. Please speak to one of our team of experts to find out the best avenue for you.
Our redENERGY G4 Pulsed Fiber Laser emits a pulsed beam, great for delivering highly precise markings or engravings. You can find out more on our pulsed products from our product data sheet here.
