Plate laser cutting of large and small parts

Cutting in the working area up to 16 x 4 m

Laser cutting is one of our most important processing methods. With our CNC laser machines, we can process a wide variety of plate metals. Our machines are equipped with these processing areas:

• 16,000 x 4,000 mm
• 6,000 x 2,000 mm

We use the BrightLine and CoolLine cutting processes for top quality sheet metal cutting.

Laser parts with higher material thicknesses

With our fiber laser, we can cut much higher material thicknesses. This machine has over 15,000 watts, which is almost three times the power of conventional laser systems. Due to the enormous output, this machine is not only able to cut thicker sheets, but also achieves a much higher cutting speed with thinner thicknesses. Up to 150 meters per minute is the highest speed possible with this machine. The working area of this machine is 6,000 x 2,000 mm.

Advantages of laser cutting

• Cutting of steel, rustproof steel and aluminium with the same machine
• Production of almost every imaginable shape
• Simultaneous processing of several orders
• The use of inert gases eliminates the need for costly reworking

How is a laser cutting machine constructed?

With our laser cutting machines we can cut sheet metal plates of different formats. The heart of the system is the laser cutting head, which is moved in three axes via guide rails. By adjusting the Z-axis, the cutting head adapts to the height of the workpiece. Controlled feeds of the X and Y axes move the laser cutting head to any desired point.

The exact position, the sheet metal panel on the processing table, is determined by a three-point measuring procedure at program start. This allows a slight tilt of the material during cutting to be corrected. The cutting head is shielded with a protective cabin. This protects against dust and gas emissions as well as reflection of the laser beam.

The strong heating of the sheet metal during the cutting process leads to the vaporisation of elements such as chromium, nickel, copper or titanium from the plate metal, which in gaseous state have a hazardous effect on health. The extraction device with professional filter system in the protection cabin minimizes these emissions.

Laser cutting machine lenses come in a variety of shapes, sizes, and materials. The most common types of lenses are spherical, cylindrical, and aspheric. Spherical lenses are used to focus the laser beam by bending the light into a more concentrated beam. This allows the laser to achieve greater accuracy and power when cutting through materials. Cylindrical lenses are used to spread the laser beam into a more evenly distributed beam, which helps to prevent damage to the material being cut. Aspheric lenses are used to create a more uniform beam, which is essential for engraving and etching.

The quality of the lens influences the cutting quality!

The quality of the lenses used in laser cutting machines has a direct impact on the accuracy and precision of the machine. Poor quality lenses can lead to inaccurate results or even damage the material being cut. To ensure the highest quality results, it is important to use lenses that are designed to withstand the high temperatures and powerful laser beams associated with laser cutting.

Danger through decomposition

Thorium fluoride is a chemical compound that can withstand very high heat. For this reason, it is extremely important to protect lenses from contamination. If particles have settled on the lenses, the energy cannot be fully released again. Depending on how dirty the lens is, it disintegrates completely.

When the lens is destroyed, decomposition products such as zinc oxide, selenium oxide and thorium on its surface are released. Thorium and selenium compounds are very toxic and cause serious health problems when inhaled or in contact with skin.

For this reason, lenses should be checked and maintained regularly.
