INNOVATIVE FEATURES OF THE METAL LASER CUTTER

LASER CUTTINGHEAD - PRECISION MEETS INTELLIGENCE
The JustLaser PCH4000 cutting head ensures excellent cutting results on any material - every time. The integrated cooling system keeps the cutting head at the optimum temperature, while the intelligent gas supply automatically provides the required process gas (nitrogen, oxygen or compressed air). Live monitoring of the gas pressure guarantees maximum process reliability: a drop in pressure is reported directly via the service interface. In addition, the cutting head has an automatic collision avoidance function and automatically measures the panel size - if the panels are crooked, the software corrects the position of the parts to be cut.

LASER SOURCE - PERFORMANCE THAT CONVINCES
The new JustCut is available in two performance levels and effortlessly cuts material thicknesses of up to 25 mm (steel). For those who specialize in thinner materials, the 3 kW version is an efficient and cost-effective entry into the world of metal laser cutting. Both variants impress with their exceptional durability and top beam quality for optimum cutting edges.

SAFETY HOUSING - MAXIMUM SAFETY FOR YOUR OPERATION
Safety is JustLaser's top priority. In normal operation, the JustCut is a class 1 laser system and therefore absolutely safe to use. A pneumatic lifting door, the robust pull-out table and the integrated drip tray are monitored by safety switches. These ensure that the laser is only activated in a safe operating state - for maximum protection of your employees.

PULL-OUT TABLE - HEAVY-DUTY HANDLING MADE EASY
With an impressive load capacity of up to 800 kg, the pull-out table makes loading and unloading the JustCut particularly convenient. Whether large or heavy workpieces - loading and unloading is child's play with this sophisticated system.

COLLECTION TRAY - A CLEAN SOLUTION FOR SMALL PARTS
When cutting smaller parts, the integrated collection tray keeps things tidy: workpieces that are not fixed by bars fall directly into the collection tray and can be easily removed via a side removal (left).

PC PACKAGE WITH TOUCH - COMFORTABLE CONTROL AT THE LATEST LEVEL
The JustCut is supplied with a powerful PC package. Windows 11 and a 21.5-inch touchscreen ensure intuitive and modern operation. This means you always have all functions in view and can control your processes with maximum convenience.

EXTRACTION + SPARK PRE-SEPARATOR - CLEAN AIR FOR BETTER PERFORMANCE
The integrated extraction solution from JustLaser guarantees a clean working environment. A high-performance turbine, silencer and mechanical spark pre-separator ensure efficient removal of smoke and particles. It is controlled directly via the laser, ensuring optimum extraction performance at all times.

AUTOMATICCENTRAL LUBRICATION - MAINTENANCE-FREE AND LONG-LASTING
Less manual intervention, more efficiency: the programmable central lubrication system lubricates critical components fully automatically at set intervals. This means less maintenance and a longer machine service life.

Software for the JustCut metal laser cutte

NESTING - USE MATERIAL EFFICIENTLY, REDUCE COSTS
The intelligent nesting function ensures maximum material utilization and significantly reduces waste. The automated placement of workpieces of different shapes and sizes not only saves material, but also reduces production costs. At the same time, optimized cutting increases productivity and contributes to sustainability.

TRAVEL ROUTE OPTIMIZATION - FASTER TO THE PERFECT CUT
Optimized cutting paths mean fewer empty runs and faster production. The JustCut calculates the most efficient route and reduces unnecessary movement of the cutting head - saving time and increasing productivity.

LEAD-IN / LEAD-OUT - PERFECT CUTTING EDGE WITHOUT MANUAL REWORK
With the automatic generation of lead-in and lead-out flags, every workpiece remains undamaged. Thanks to this function, time-consuming manual creation is no longer necessary and reworking is reduced to a minimum.

BARS - PRECISE FIXING FOR SMALL PARTS
Small parts that should not fall through are held in the material with the help of automatically generated bars. The software creates the starting point directly at the bars and adds lead-ins if required. This ensures a clean cut and minimizes post-processing.

FLY-CUT - HIGH SPEED FOR SERIES PRODUCTION
Fly-Cut offers an innovative solution for frequently recurring, simple contours and hole patterns: the laser head moves continuously at high speed while the laser beam is activated intermittently. This enables extremely fast processing and reduces operating costs - ideal for series production.

AUTOMATIC SHEET MEASUREMENT - PERFECT USE OF RESIDUAL MATERIAL
With the PCH4000 cutting head, the JustCut automatically measures residual sheets and optimally adjusts the geometries to be cut. This further reduces material consumption and maximizes the use of resources.

DIGITAL MAINTENANCE LOGS - EVERYTHING AT A GLANCE, AVAILABLE AT ANY TIME
All maintenance data is documented directly in the software and can be managed digitally. User entries enable seamless documentation and facilitate tracking by JustLaser.

NESTING WITH JustCut Metal Laser Cutte

Nesting (automatic nesting)

Nesting technology is an innovative software solution that is supplied with our laser cutter and ensures an optimal arrangement of the parts to be cut on the material. This technology saves time, reduces material waste and increases the efficiency of the laser cutter. Nesting technology allows materials to be optimally utilized by extracting more parts from each material sheet. The software analyzes the shapes of the parts to be cut and automatically places them as close together as possible on the material. This is known as true shape nesting. This minimizes waste between parts and leads to greater cutting efficiency. 

The advantages of nesting technology:

  • Automatic calculation of optimum area consumption

  • Minimization of material wear

  • Nesting objects within objects

  • Optimum use of materials by utilizing remaining areas

  • Object distances are adjustable

  • Fully or semi-automatic nesting with preview

  • Objects can be prioritized

Data preparation for laser cutting

  • With modern laser cutting software, lead-in/lead-out, starting point optimization and cutting paths are optimized so that the laser always chooses the fastest and shortest path.

     

    The advantages:

  • Range of professional design tools for demanding tasks

  • Direct CAD data transfer

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

Cooling systems for the JustCut laser metal cutte

To ensure consistently high processing quality, it is crucial that the temperature of the laser source, the laser cutting head and its power electronics are kept at a constant temperature. The heat to be dissipated is proportional to the power output, i.e. the laser power output varies greatly within a short period of time. Cooling must be adjusted quickly and preferably continuously (steplessly).

 

OUR ADVANTAGES FOR YOU:

  • Opt for a solution that only ever dissipates the exact amount of waste heat generated and therefore keeps the operating temperature of the laser source constant
    . This solution therefore also helps to conserve resources.
  • Benefit from exactly the same processing quality, regardless of whether the laser is switched on after the weekend or whether it has been working for you for hours.

Metall Laser Cutter FAQs

Which laser is ideal for cutting?

You can cut organic materials like wood, plastic and textiles with both the JustLaser Large Laser Cutter and the JustLaser Laser Engraver. The JustLaser Large Laser Cutter can also cut metals with a thickness of up to 4 mm. The JustCut range of products with an output of 1kW - 3kW from a fibre laser can cut metals with a thickness of up to 10mm.

Laser applications

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. .

Which laser should I use for cutting metal?

For applications with metal, we recommend our JustLaser JustCut fibre laser. This is ideal for processing metal, sheet metal, copper and aluminum. A compact fibre laser machine equipped with nLIGHT laser sources with a laser output of up to 3kW.

How strong does a laser need to be to engrave metal?

Metals are engraved using fibre lasers. An average power output of 20 watts should be sufficient. The pulses need to be short and the peak pulse power needs to be in the range of several kilowatts. Laser sources (with a suitable beam guide and focussing lens) have been installed at the JustMark Lasermarker workstations for exactly this purpose.

You can engrave metal with a CO2 laser if you apply a special paste (e.g. Thermark) to the metal workpiece beforehand. This paste is then “burned in” to the metal thanks to the high, laser-induced temperature increase. That makes the inscriptions very robust and durable.

How strong does a laser need to be to cut metal?

The wattage to use depends on the properties of the respective material and the thickness of the metal plate. Aluminium up to 1.5mm thick, stainless steel up to about 3mm thick and construction steel up to just over 4mm thick can be cut with CO2 lasers with 650W laser output and oxygen inflow.
