If you decide to start production on a CNC laser cutting machine, you will inevitably face serious competition. Until 10-15 years ago, it was possible to make a fortune in laser cutting without much effort, even with lackluster results. But now everything has changed.
Today's laser cutting market is much more demanding when it comes to the quality of the end result.
Customers are no longer willing to buy plywood products with a burnt edge or metal products with drossed edges. The market is still highly lucrative, but to compete in this market, the choice of equipment must be taken seriously.
The CNC laser cutting machines market is overfull of similar CNC lasers with the same-type descriptions. Such equipment is expensive, and, before you purchase it, you need to figure out what to point out. And this article will help you with that.

Advantages of CNC laser cutting:
- Laser cutting speed up to 150 mm/s depending on machine and material being cut.
- The laser beam diameter at the focus point is hundredths of a millimeter, capable of piercing a hole thinner than a hair and cutting highly detailed layouts of complex configurations.
- The CNC laser is non-contact, and therefore the material does not need to be fixed on the work field, which saves working time.
- After cutting, the end face is obtained without soot, dross or taper. The laser leaves no chips and cracks or deformations on the material, unlike other machining methods,
- The CNC laser control system and software provides a wide range of tools for operation, automates the process, and minimizes the chance of defects.
- The laser cutting machine can not only cut but also engrave material. The combination of cutting and engraving makes it possible to produce more complex and sought-after products.
- The CNC laser is easy to maintain and requires almost no consumables. The CO2 laser tube lasts up to 3 years when properly operated, and the fiber optic emitter lasts up to 11 years.
What is produced with CNC laser cutting machines?
If you choose the right type of emitter and other parameters, the laser cutter will cut most materials with minor exceptions.
Materials that can be cut with a laser cutting machine:

How to choose a laser cutting machine. Basic criteria
First of all, decide what you want to do with a laser machine and what materials you want to process. This will determine most of the parameters of your future laser machine and, above all, the type of laser emitter.
Laser cutting machine emitter type
Laser cutting machines are divided into two basic types: CO2 and fiber optic. The type of emission determines which materials the machine can cut.
CO2 laser cutters are capable of cutting non-metallic materials:
- cardboard, corrugated cardboard, foam board,
- foam plastic,
- foam and isolon,
- PET and other plastics,
- leather and faux leather,
Normally, CO2 laser cutting machines are not capable of cutting metals.
An exception to this rule are the Wattsan NC series hybrid CO2 laser cutters. They cut metals up to 2 mm thick thanks to a special metal laser head, an auxiliary gas (oxygen), and laser power from 130 to 180 watts. In addition, they can cut plywood up to 15 mm and plastics up to 25 mm.
The NC-series hybrid laser cutting machines are available in two work area sizes:
- Wattsan NC 1390 with a work area size of 1300x900 mm.
- Wattsan NC 1612 with a work area size of 1600x1200 mm.
If you are interested in other work area sizes, let Virmer's manager know, and, thanks to our cooperation with Wattsan, we can produce a machine with the desired work area size.
If you are interested in learning more about CO2 laser machines, we recommend reading the article «What is a CNC CO2 laser and how it works» (LINK)
Fiber laser cutting machines cut the following materials:
- ferrous metals,
- stainless steel,
- other metals and alloys.
It is impractical to use fiber laser cutters for other materials, as the cost of such equipment is many times higher than CO2 laser machines. In addition, because of the unsuitable wavelength, fiber lasers do not work with most non-metallic materials.
Please note that CO2 emitters for cutting are claimed to last between 3,000 and 10,000 hours (4 to 13.6 months) depending on brand and wattage, and fiber optic emitters are claimed to last up to 100,000 hours (11.4 years).
Once you have decided on the type of emission, you have to work out how much power you need.
Laser cutting machine emitter power
The power required depends on the thickness of the material and directly affects the operating speed.
CO2 laser cutting machine power
CO2 laser machines are designed on the principle of Flying Optics; they have a system of mirrors which reflect the laser beam using mirrors attached to various, including moving, parts of the housing. As the laser beam travels in the air, the beam inevitably scatters and loses the more of its power the greater distance it travels. For this reason more powerful laser tubes are required for machines with larger work area sizes.
For productive cutting on machines with a work area of up to 600x900 mm, emitters with a power of 40 to 120 W are used. For machines with a larger work area, laser tubes with a power of 100 to 180 W are used.
There is a "conventional" formula for calculating the power required, according to which 10 watts of power are consumed for every 1 mm of plywood thickness. For most plastics, this is conventionally 1.5 mm per 10 watts.
In order to extend the service life of the laser tube, we recommend using it at no more than 80% of its power. Keep this in mind when calculating the required power.
For example, the Lasea F2 80W laser tube will cut plywood up to 8-10 mm, but the recommended maximum thickness is 8 mm.
Also note that if the laser tube has two power rates, e.g. 80-95 W, the first number is the nominal power and the second number is the maximum power. Most of the time, the laser operates at its nominal power.
Fiber laser cutting machine power
The required power of a fiber laser will depend on the thickness and the type of metal. Mirror polished stainless steel, for example, is more difficult to cut than ferrous steel, as it has a higher reflectivity.
The power of fiber optic emitters varies from 1000W to 15000W. The operating speed is not as easy to calculate as with CO2 laser machines, but there are tables that show the type of material, the laser source power, and the auxiliary gas. These tables show what thickness and at what speed can be cut with certain input parameters.
For example, a 1kW machine will cut 1 mm of stainless steel at 20 m/min. At 3kW, the same stainless steel sheet can be cut at 35 m/min, while a 6kW emitter will cut 1 mm stainless steel at 60 m/min.
Depending on the type of metal, the speed of the laser cutter will be different! In order to get help in choosing the emitter power, please contact your Virmer manager.
The next thing to consider when choosing is the size of the work area.
Laser cutting machine work area
The size of the work field determines the maximum sheet size of the material you will be able to process. For example, if you want to cut corrugated cardboard boxes, then the Wattsan 2030 Flat Bed with a work field of 2000x3000 mm is the best choice, because the net of one box will be quite large. And if you need to cut packaging for small souvenirs, then the Wattsan 6090 with a work field of 600x900 mm will be enough.
Consider the maximum size of the final product when selecting the size of the work area of the machine.
The size of the work field will also determine whether or not you need a separate work place in the workshop to pre-cut the material. For example, the Wattsan 1610 LT large-format laser cutter has a through table with a work field width of 1600 mm. This means that you can cut sheets of most standard materials on this machine if you pull them through the through table.
The larger the work area of the laser machine, the less often you need to change material, which speeds up the production process.
To speed up the process of material change when working on fiber laser cutters, we recommend looking at machines with interchangeable tables, such as the Wattsan 1325 Tablechange.
Reliability of the machine frame, bed, and gantry
When choosing a machine, pay special attention to the design of the frame and bed of the laser cutting machine. They affect the accuracy of work, especially during continuous operation.
CO2 laser cutting machine frame
CO2 laser cutting machines must have an internal reinforcement frame. It is quite difficult to see it without disassembling the entire machine, but its presence can be easily checked - try shaking the machine with your hands. A model with an internal reinforcement frame is virtually impossible to shake by hand. If there is no frame inside, the machine will wobble.
The lack of internal frame reinforcement leads to a rapid drop in cutting accuracy.
CO2 laser cutting machine bed
The reliability of the machine is also affected by the housing itself, that is, the housing material and its thickness. The best solution for the housing is steel with a thickness of at least 2 mm. On Wattsan CO2 laser machines, for example, the bed thickness is 2.9 mm.
CO2 laser cutting machine gantry
The next element of the machine that is subject to constant loads is the gantry, because it is where the working head is attached. The thickness of the gantry can easily be checked by opening the side cover of the machine. A thin gantry will deform over time, which reduces accuracy and repeatability of work.
With a profile gantry up to 7 mm thick, a robust housing, and frame construction, Wattsan machines are designed to work around the clock. They have a service life of over 10 years without loss of precision.
Fiber optic laser cutting machine frame and gantry
A laser machine for metal cutting is subject to much more load, from the weight of the material itself to the idle movements of the portal at a speed of up to 120 m/min.
A metal laser machine must not only withstand the load of material and movements of the laser head, but also eliminate vibrations so that work accuracy is not compromised.
Wattsan laser metal cutting machines have an all-welded frame with a cross section of rectangular pipes up to 10 mm. Inside the frame there are reinforcement baffles every 400 mm. To relieve the stress on the metal, the finished frame is annealed in a special furnace with strict temperature control.
The metal laser machine gantry is more solid compared to CO2 machines. The best modern solution for a fiber laser machine would be an aluminium profile gantry; it is lightweight, robust, and not subject to oxidative processes.
When it comes to the speed of laser cutting machines, it is important not to confuse speed of operation with idle speed. Generally, operation occurs at much lower speeds than idling. For example, the idle speed of a CO2 laser machine reaches 500 mm/sec, but you will cut 3 mm thick plywood at about 35 mm/sec, depending on the power of the emitter.
Laser cutting speeds will vary, depending on the material, its thickness, and the power of the laser emitter.
All of the above is also true for fiber optic lasers. But for this type of equipment, the idle speed is more important for some tasks. For example, if it is necessary to cut holes in the corners in the sheathing of any metal structures, in this case the machine needs to move around the entire work field from corner to corner, and the operation speed will directly depend on the speed of idling and acceleration.
Complete set of a laser cutting machine
CNC lasers are complex equipment in terms of machine tool building, and all the difficulties, as always, lie in the details. The most important thing is to calculate the loads and choose all the components correctly so that they fit each other and the loads.
For example, the Wattsan fiber laser cutting machines are equipped with Mitsubishi servo motors. It would seem that this is already good, because this is a reliable brand, and its mere presence speaks of the quality of the machine. But no, if the rest of the machine components are not designed for the loads that these engines will give, then such a machine will not last long.
Wattsan engineers have been designing, manufacturing, and refining their machines for more than 20 years.
This allows the company to take a strong position in the market and be responsible for their machines. All machine components are carefully designed and tested under maximum loads. Everything, from the engine to the end sensors, has been chosen according to the principle of sufficiency, which means that the best possible parts have been selected to complete the machine, without chasing after expensive brands.

The last thing to consider when buying a laser machine is the reliability of the supplier.
Supplier reliability and support. How to evaluate
When buying a machine it is important not only to get a quality product, but also to be sure of the supplier's support should you need it. The main characteristics that speak for reliability are experience and production volumes, warranty and service, as well as commissioning and training.
Pay attention to those who have been in production for a long time. It is these companies that value their reputation and, thanks to their experience, know how to make really high-quality equipment.
High quality equipment is inevitably in demand. Find out how many machines the manufacturer sells and in which regions. Doubts may be caused by small production volumes and local limitations of the supplier.
Warranty and service
Specify whether the supplier will be able to implement its warranty obligations in your region and whether it has post-warranty services.
Commissioning and training
Setting up a laser machine is not too difficult, but it is definitely not a task for someone without experience. Check if the supplier can provide commissioning, and if he has a training service for the machine.

What is a CO2 laser cutting machine?
A CO2 laser machine is a numerically controlled machine that can cut and engrave quickly and precisely non-metallic materials such as plywood, wood, MDF, various plastics, textiles, leather, fur, and many other materials using laser emission.
What kind of wood can be cut with a laser?
With a laser cutter with a carbon dioxide (CO2) emitter, you can cut any kind of wood. The recommended thickness for this type of cutting is up to 10 mm, as laser exposure to greater thicknesses causes fouling on the cut.
What is the difference between CO2 laser and fiber optic laser?
The difference between a CO2 and fiber laser is the wavelength of laser emission. With CO2 lasers it is 10.6 µm, while with fiber lasers it is 1.06 µm. The wavelength determines the possibility of treating particular materials.
CO2 lasers can work with wood, plywood, veneer, MDF, cardboard, paper, and other wood materials, plastics and polymers, such as: PET, acrylic, rubber, foam rubber, paronite, and others, with fabrics, leather, leatherette, and fur. In addition to cutting, CO2 laser machines can also engrave ceramics, stone, glass, and mirror.
Fiber optic machines work with ferrous metals, stainless steel, aluminium, titanium, copper, brass, and precious metals. Also, they are capable of working with polymers and plastics, some types of leather and faux leather.
What can be done with a laser cutting machine?
The laser cutter can be used to cut almost any thickness of material. For non-metallic materials, CO2 laser cutters are intended, and for metals - fiber optic laser cutters.
