Laser Cutter Types

Before investing in a high quality laser cutter machine it is important to understand its main uses and functions. It is also essential to get the best laser cutter machine according to what you aim at producing. The more you know about the machines the more likely you will to reach the expected results.

Fiber laser cutting machine

The fiber laser cutting machine is the fastest way to cut thin metal sheets. Especially suited for applications that do not require superior surface quality at the cutting edges, it can be used to cut thin to medium materials.

Increased energy efficiency

In laser cutter and its applications, energy makes up 5% to 7% of the total cost per part. The co2 laser cutter machines also include additional components for energy savings. To create the most efficient configuration for you, you should get advice and discuss all options with a specialist. The more you use these machines the more you will save cash, especially if in the long run.

The safety factor

Fiber laser cutting machine uses a wavelength of 1 μ and therefore require the application of very strict safety criteria. Machines must be in a completely isolated environment to reduce the operator’s ability to influence the process and prolong downtime in the event of a problem. On the other hand, since they only use 10 μ, the CO2 lasers allow the operator to approach and restart the cutting process as soon as possible in case of an incident.

C02 laser cutting

The co2 laser cutter is ideal for processes that require a high degree of accuracy. The surfaces produced are superior to those created by fiber laser cutting. And although it does not rival milling, it is much faster and therefore much more profitable. Able to cut materials from the thinnest to the thickest, it is also faster than cutting with fiber in materials with a thickness exceeding a certain value.

Keep your maintenance costs down

The co2 laser cutter is quite complex and thus require maintenance, especially of turbines and mirrors. Given the inherent costs, make sure you choose a machine designed for maximum reliability. For example, some machines require only maintenance work performed at extremely spaced intervals. A manufacturer also guarantees the turbine for 24,000 hours.

Automate to increase productivity

Supported by charging robots, a CO2 laser machine can work continuously without interruption. More efficient and economical than a fiber machine in this type of application, this results in a low

Lower costs per piece

70% of the costs of laser equipment are derived from the initial contract and not from everyday operating expenses. In financial terms, co2 laser cutter offers enormous advantages over fiber-cutting machines in applications involving complex shapes and extremely demanding levels of accuracy and repeatability. This is due to the fact that achieving identical results with a fiber cutting machine would entail costly upgrades, such as adding rigidity and setting up an optimized linear motor, which would ultimately make this option too expensive.

Air Assisted Laser Cutting and How It Can Help You

Metal laser professionals know that there’s more than one way to use a laser cutting machine. They also know which gasses work best. Most of them opt to use nitrogen or oxygen, however air assisted laser cutting may be better for them. Its cost efficiency is one of the main reasons to switch, but is it right for you? Here are a few things to consider before making the switch.

How It Works

Fiber laser cutting machines and CO2 lasers don’t rely strictly on the laser to penetrate metal.  An assisted gas can be emitted from the laser head nozzle during processing. For many years oxygen was the gas of choice until it was discovered that nitrogen produced a cooler cut which resulted in cleaner edges. Using air is similar to nitrogen especially since air is 80% nitrogen in the first place. Although the two gasses are similar, air provides a slightly higher quality at a lower price. This has fabricators pretty eager to make the switch.  You can use fiber laser marking or cutting machines for extremely detailed marking, engraving as well as  for deep cutting metal such as brass or copper and of course stainless or soft steel.  The Fiber beams kerf is clean and roughly 10x smaller compared to co2.

The Perks of Air Assist

The clean up after nitrogen use with a laser cutter can be a time consuming clean-up effort. When using air as the gas of choice the clean-up part of the job is significantly reduced if not eliminated altogether. Nitrogen prices have gone up 90% and is expected to continue to rise, however air is much cheaper and the prices are fairly stable. Air assist has been developing since 1998 and with the recent improvements of technology air assist is becoming more common within the industry.

When to Use Air

Although air assist is on the rise it is not always the best choice for the product. Air is best used on thinner objects that need to be cut and stainless steel. Nitrogen still provides a quicker cut and a cleaner edge, so if your company is responsible for cutting objects for the food and aerospace industries then it is best to continue to use nitrogen to avoid any mishaps. The cosmetic industry is another example of when nitrogen is a better option. A lot of those products cannot have any imperfections on them and while air does provide quality work it could leave some minor imperfections in the product.

Air assisted gas is a progressive resource and a great choice if a company is seeking to lower cost and raise production. If the industry that you are in fits well with the type of materials the air assist works best with then it will be fairly easy and wise to make the transition. With everything there is always pros and cons to any situation. After learning more information about air as it relates to nitrogen take all factors into situation and make the correct choice for your product. If the type of work you do varies then using both could work. You could save money when necessary and continue to use nitrogen or oxygen when the product calls for it.…
