The Laser Cutters from JustLaser

Efficient laser cutting machines

 

Fastest large format laser engravers

With a speed of up to 3.8 meters per second, we have the quickest laser cutting machine for engraving large areas on the market (from a working area of 1320 x 1270 mm). This means that you can achieve a better output at the highest standards of quality – the cutting and engraving quality sets unparalleled standards.

Greater flexibility with a laser cutter

You decide which materials are cut, not the laser cutter: regardless of whether it’s metal, wood, acrylic or aluminium. Thanks to the JustLaser Large Laser Cutter, you can customise your applications at any time.

Intelligent axis extractor

The axis extractor keeps the laser head clean when engraving or cutting any material, meaning it doesn’t need to be cleaned. During the development of the laser head, special attention was paid to ensuring that the weight was kept as low as possible in order to reduce the flywheel mass. That means we can achieve greater engraving speeds and lower maintenance costs.

CE certified Laser Class 2

Thanks to the sophisticated safety concept of the JustLaser Large Laser Cutter, it is the only open large laser cutter of its class which is CE-certified for laser class 2 (for the processing of organic materials). The benefits here are obvious: on the one hand, fewer safety measures and training courses for employees are needed, and on the other hand, there are also structural measures that need to be considered.

HYPER-DUAL MOVEMENT

The hyper-dual system for the portal axis on our laser cutter has an EC servomotor on each side which moves the portal using a sprocket and (fixed) cograil. The two motors are perfectly synchronised to each other, thus ensuring the axis runs smoothly and without any issues. The robust, generously-sized mechanical structure can convert high, even jerky torques from the servomotors into strong acceleration with simultaneous precise positioning and long service life. Positioning and repetition accuracy is realised in terms of control technology by 24-bit encoders of the motors and the fast DSPs. This means that we can often exceed our customers’ requirements with regard to axis dynamics and precision.

SAFETY SYSTEMS – LASER CLASS 2 

Benefit from our safety systems: emergency stop switches, laser safety goggles and a sealed beam path between the laser source and delivery nozzle tip are just some of the safety features for the JustLaser system. This and much more means that the JustLaser Large Laser Cutter is the only laser in its class that is officially CE-certified for laser class 2 (for processing organic materials). More information on laser class 2 here!

LASER SOFTWARE AND HARDWARE

Each JustLaser Large Laser Cutter comes with a high-performance computer with a Windows operation system. Connecting the computer to the laser is simple thanks to Ethernet technology and the KCAM laser software.

IMPROVED VACUUM

Vapours produced during the engraving process can be efficiently absorbed with a newly designed portal vacuum. Thanks to the improved vacuum, metal sheets can be safely stabilised, and any vapours produced during the laser cutting process can be drained outside.

PROGRAMMABLE COMPRESSED AIR

When installing the metal-cutting option, you can connect and use up to three gas supplies simultaneously. By way of an example, this means you could quickly pierce stainless steel with oxygen, and automatically switch over to nitrogen for the cutting profile. This gives you a result with a shiny edge quality and a burr-free cut.

SUPER-PULSED LASER TUBES 

Each JustLaser Large Laser Cutter comes with a super-pulsed laser tube. This means more output for your applications because super-pulsed means that the laser tubes provide much more than the purchased output in individual peaks. A 650W laser tube can supply more than 2,000W (2kW) of peak power for a brief period. This means a super-pulsed laser tube can, for example, help produce less browning on cut edges as the high peak performance means the material in the cutting gap evaporates faster and the short interaction duration inhibits heat conduction. The power is directed into a smaller, defined volume, which in turn means that the cutting groove is reduced.

Nesting Software for the laser cutter

NESTING (AUTOMATIC NESTING)

The technology known as nesting is an advanced software solution that is provided together with our laser cutter. It enables efficient placement of the workpieces to be cut on the material and thus guarantees optimum utilization. This method saves time, minimizes material waste and increases the performance of the laser cutter.Nesting technology is used to achieve maximum material utilization by making it possible to obtain a larger number of parts from a single piece of material. The software automatically determines the best possible arrangement of the workpieces by placing them as close as possible to the starting material. The result is a significant reduction in waste and improved efficiency in the cutting process.

 

THE ADVANTAGES OF NESTING TECHNOLOGY:

  • Automatic calculation of optimal space consumption
  • Minimization of material wear
  • Nesting objects in objects
  • Optimum use of materials by utilizing remaining space
  • Object distances are adjustable
  • Fully or semi-automatic nesting with preview
  • Objects can be prioritized

This function therefore complements the Laser software KCAM. 

 

The advantages:

  • Range of professional design tools for demanding tasks

  • Direct CAD data transfer via the AutoCAD plug-in

  • Various import filters for file formats such as AI, EPS, PDF, DXF, HPGL, G-CODE and others

What is laser cutting?

The processes used for laser cutting – laser flame cutting, laser fusion cutting and sublimation cutting – are dependent on the material from which a workpiece is made.

 

LASER FLAME CUTTING

For laser flame cutting, oxygen is used as a cutting gas and as an additional energy supplier, whereby combustion is generated in a specific place when the material is melted using a laser cutter. It is necessary to carry out post-processing work with laser flame cutting as, unlike in laser fusion cutting, the process causes the edges to be oxidised, resulting in the formation of burrs. Ideally, however, the formation of burrs can be avoided if the laser parameters are properly defined.

LASER FUSION CUTTING

In laser fusion cutting, a metal – frequently aluminium alloys or stainless steel – are melted due to the heating effect of the laser beam. As part of this, an inert gas is usually blown into the cutting joint to prevent oxidation at the edges. As this does not result in the formation of burrs, the process is suitable for all tools that do not require further processing or where no material changes are desired. A high-performance solid-state laser is usually beneficial for this method.

SUBLIMATION CUTTING

The special thing about sublimation cutting is that the laser machine causes the material to be immediately vaporised without having to pass into a liquid state. This creates a particular fine, burr-free cut. This process is often used for medical technology.

How laser engraving works

In contrast with mechanical engraving, where material is removed through scratching, piercing or chiselling, laser engraving is carried out with the help of the energy of a laser beam that vaporises the surface.

LASER ENGRAVING

With laser engraving, a digitally-controlled laser heats up the surface of a work material so much that it evaporates to a certain depth, creating a permanent and abrasion-resistant engraving. The smart laser technology of the JustLaser Large Laser Cutter wins people over thanks to its maximum repetition accuracy – no manual skills or additional tools are necessary.

ABLATION

White marks can be made on anodised aluminium using CO2 lasers and fibre lasers. Setting the parameters for this is very simple. The chromophoric metal salts are thermally corroded by the rise in temperature, meaning that the inscription is white. Naturally anodised aluminium (i.e. with a metallic sheen but without any colour) and bare aluminium can be given dark or light inscriptions. With anodised aluminium, the extremely mechanically tough, chemical-resistant and non-electroconductive layer of aluminium oxide is retained.

With painted metals or plastic laminates (at least 2 layers), the coat of paint or top layer of plastic can be removed using a CO2 laser, often without leaving any residue behind.

 

Laser Cutter FAQs

How does a CO2 laser work?

A CO2 laser is a gas laser which is often used for materials processing. The laser-active medium is made up of a mixture of carbon dioxide, helium and nitrogen. The stimulation is caused be either: a) electromagnetic waves (typically 48MHz or 86MHz), which are transmitted into the resonator via antennae, or: b) via glow discharge in the gas mixture through applied high voltage (typically 20,000 - 30,000 volts).

How does Laser Cut work?

The processes used for laser cutting – laser flame cutting, laser fusion cutting and sublimation cutting – are dependent on the material. For laser flame cutting, oxygen is used as a cutting gas and as an additional energy supplier. The high temperature in the cutting gap and the oxygen start an oxidation process (“combustion”), the high process heat released from which supports the cutting process. For laser fusion cutting, on the other hand, metals are melted under the heat of the laser beam and driven out of the cutting gap by the high pressure of the process gas. This often leads to lower cutting edge quality. Cutting processes can also be carried out with high-performance fibre lasers with nitrogen inflow (less commonly, 400W with CO2). This process, in which cutting edges retain their metallic sheen, is slower than flame cutting, although cutting edges usually turn dark in flame cutting. .
