Flat-bed (2D) laser cutting in Dunakeszi

The worldwide spread of laser cutting technology began in the 1960's. In the early 70's the first CNC laser cutting machines appeared, which offered greater productivity. In Hungary, the first machines appeared in the 1980's and soon became popular with both the sheet metal industry and clients. Already at that time, the sheet metal working capabilities of laser cutting machines were characterised by burr- and slag-free, precise laser-cut sheet materials and low scrap ratios.

Laser cutting since over 10 years in Dunakeszi

The diversity of our clients and products has required the continuous development and modernisation of our technology since the beginnings. One of the most cutting-edge technologies for sheet metal working is laser cutting, for which we use one of the best products of the industry, a Trumpf TruLaser 3030 laser cutting machine, which creates precise laser-cut sheet materials.

The most widespread laser technology is laser cutting, as it enables us to produce a high-quality cut surface in a cost-effective and flexible manner, with excellent utilisation of the material, and rapidly. Typically used for carbon steel, stainless steel, or aluminium, the laser beam used in laser cutting allows the creation of both simple and complex forms, perfect curves, and precise corners from both thinner and thicker sheets, with perfect precision.

We also offer sheet metal working of materials provided by our clients, but thanks to our considerable stock our partners can save both time and money. If unique or special material types or sizes are required, we will be happy to obtain sheet materials of the appropriate quality and dimensions from which finished laser-cut products can be created precisely.

We offer laser cutting to our partners at a favourable price, with short deadlines and timely delivery, just a short hop away from Budapest, in Dunakeszi.


TRUMPF TruLaser 3030

The TruLaser 3030 machine offers flexibility and economy to our partners, especially in the case of structural steel, for which laser cutting provides a profitable solution for any sheet thickness. The use of a flat-bed laser guarantees a major productivity advantage for thinner sheets.

We can undertake the laser cutting and machining of special custom parts in small- to medium-sized lots.

Dimension ranges for laser cutting:
1500 x 3000 mm - Steel: 15mm, aluminium: 8mm, stainless steel: 12mm

Laser cutting of aluminium and stainless steel

Our laser cutting machine can also handle aluminium, stainless steel, and alloys, for which we use inert gas (nitrogen) laser cutting. The 0.2-0.3 mm laser beam melts the material to be cut, then high-purity nitrogen applied with a pressure of approx. 20 bar removes the melted raw material. With nitrogen assisted laser cutting the discolouration of the material at its edges is minimal; in order to protect the surface we use a so-called laser-cuttable membrane.

When using a laser-cuttable membrane, in the first step we evaporate the membrane along the cut lines using significantly reduced power, then, after adjusting the power to the cutting level, cut the material. The advantage of this method is that the membrane can remain on the sheet even until its final use, which prevents surface damage.




Laser cutting carbon steel

The most common material used in laser cutting technology is carbon steel.

For carbon steel, unalloyed and low-alloy steels the material is cut using oxygen assisted laser cutting, in which the focused laser beam first heats up the material to be cut to its melting point, then high-purity oxygen is injected into the cutting gap, which feeds combustion to burn the material.

The oxygen injected at a pressure of 2-3 bar also helps blow out the melt and slag.


Material transport for laser cutting machines

The raw materials for laser cutting are transported using the Trumpf LoadMaster sheet loading unit, which transport sheets using suction cups from the loading station to the pallet changer, where it deposits them.

The automatic transport ability of LoadMaster relieves the burden on the operator and increases safety during operation, while the greater positioning accuracy of the automated unit enhances the operational reliability of the entire system, with only small set-up space required. Another important benefit is that the surface of the sheet does not become damaged or scratched during loading. This is particularly important in the case of aesthetically sensitive parts produced from factory-anodised aluminium or mirrored/brushed stainless steel.
