Manufacturing cutting technology!

We make the cut!

The "Cutting" competence center is our newest member in the production chain. In addition to the material specification, decisive factors for the selection of the suitable cutting process are the material thickness and the required properties. We process all common sheet formats from small to large. On request, we offer you the best cutting edge quality with the highest precision. Efficiency and continuous optimization of processes are essential features of our production.

2D laser cutting – Fully automated cuts

Economical 2D laser cutting penetrates even large material thicknesses

Precise, fast and above all economical – this is how briefly and succinctly the results of two-dimensional laser cutting can be put in a nutshell. One glance at how the industrial hot cutting process works illustrates the advantages of 2D laser cutting. Put simply, the system consists of a laser unit and a device to hold the material. A computer control system ensures that all movements along both axes are carried out as calculated and that the laser beam is guided precisely. Numerous sensors monitor these processes and continuously compare the actual situation with the calculated target situation. This ensures the high precision of the 2D laser cut.

The actual cut is made by the high energy concentrated in the fibre laser. The energy strikes the material to be cut and causes it to melt by means of heat. After the 2D cutting process, the cut edges are cooled using CO2 – and molten metal slag is removed. The advantages of 2D laser cutting lie in the comparatively low material stress. The energy of the 8 kW laser beam allows high intensity, precision and speed, with which even large material thicknesses can be separated. Our processing spectrum ranges from 0.5 to 30 millimetres of material thickness with small to large sheet sizes. Thanks to our highly advanced degree of automation, materials can be loaded and unloaded as well as labelled fully automatically.

Separation via high pressure

Water jet cutting cuts through metals without thermal stress

Cold cutting processes such as water jet cutting are especially suitable as cutting methods when processing temperature-sensitive materials. In addition, water jet cutting is considered to be environmentally friendly and low in emissions compared to laser cutting.

The functional principle of this process is easy to understand: it is based on high water pressure. This pressure strikes the surface of the workpiece. A pressure of 1,000 to 4,000 bar and an adjusted working speed ensure that a wide variety of materials can be cut, such as titanium, (stainless) steel or aluminium or special materials. A typical feature of this process is that the material is not stretched during the cutting process. The decisive factors for the cutting depth in water jet cutting are the amount of pressure applied when striking the material surface, the diameter of the nozzle used and the admixture of an abrasive material.

We process large and small format sheets in material thicknesses from 0.5 to 160 millimetres. Our water jet cutting system has a pump capacity of 74 kW and an integrated 5-axis angle cutting head, which also makes angled cuts possible.

Cutting in the third dimension

Three-dimensional laser cutting ensures precise cutting results

3D laser cutting is a classic process used by metalworking companies. It enables us to perform complex cuts on three-dimensional objects. The precision of the cutting results and the range of applications of the process are among the basic advantages of 3D laser cutting. A key functional feature of the cutting process is the option of controlling the laser on several different axes as well as the automatic movement of the respective workpiece. Three-dimensional laser cutting also makes it possible for us to provide workpieces with, for example, cutouts or contours after forming.

Our fibre laser has an output of 4 kW and processes material thicknesses from 0.5 to 6 millimetres. The system truly demonstrates its capabilities when it is directly integrated into automated process chains and workpieces can be processed immediately after previous work steps. The actual cuts are made fully automatically. The precision of the cutting result is ensured by internal sensors. In a continuous process, these sensors compare the actual state with the calculated target state and, if necessary, intervene to control the process.

Besides precise cutting results, 3D laser cutting offers above all the option to produce in series. Our 3D laser cutting system can perform cuts as often as required with consistently high quality and precision.

Quality down to the last millimetre

Deburring and brushing processes ensure our high product quality

Once cutting processes such as water jet cutting and 2D laser cutting or even punching have been completed, we usually devote ourselves to tasks that serve to ensure our product performance. Deburring or brushing are two such tasks. For components with a material thickness of up to 50 millimetres that have been punched, lasered or cut by water jet, the deburring of cuts is carried out in a “throughfeed” process – including the effective extraction of air containing pollutants.

Depending on the manufacturing process, cut components always have a more or less pronounced burr, which can be removed at the customer's request. Another advantage of this process is the reduced risk of injury during subsequent manual processing of the products.
