10KW PHOENIX FL-6020 & 10KW TAURUS 24
Founded in 1886, and still run by the same family, Ludwig Esser Metallbau was originally set up to construct and test weighbridges for carts and wagons. It later moved into metalworking for the construction industry. At that stage it added a sheet metal processing capability and installed two LVD press brakes. Since then, it has constantly extended its capabilities so that it can now process sheets up to 12 m in length and 3 m wide. Typical applications include conveyor systems for the paper and cement industries and heavy-duty sawmill equipment.
It is now a subcontractor for laser and waterjet cutting, bending, profiling and the fabrication of welded assemblies. It processes all standard, high-strength and wear resistant steels, stainless steel, aluminium and special alloys. Customers come from industries including mechanical and plant engineering, bulk and component handling, agricultural machinery, commercial vehicles and environmental technology. They come from all over Germany, as well as the Benelux countries, France, Poland, the Czech Republic and
The Phoenix FL-6020 is an allround performer with flexible automation allowing it to effectively process a wide variety of materials,
components and batch sizes. Full automation can be used on large batches, while the machine can still be used with manual loading and
unloading for low volumes and one-offs.
The Taurus is LVD’s revolutionary fiber laser cutting machine for extra large format material processing. Its unique modular construction
allows it to be configured to suit a customer’s precise requirements. It can accommodate parts up to 3.2 m wide and 30 mm thick, and
the basic 10 meter bed length can be extended in 4 m increments up to a maximum of 42 m. The machine is equipped with state-of-the-art bevel head technology.
Managing Director Ludwig Esser explains that the motivation for investing in these new LVD machines was to strengthen the company’s competitiveness by increasing productivity and adding new capabilities.
"The Phoenix has 2 by 6 m sheet capacity and we established that we cut a lot of material in this size range. We decided that this highly productive machine should be at least partially automated, so we specified it with an automated loading and unloading system."
This allows us to run unmanned at night if we want to, but also gives us the flexibility to load single sheets manually for one-offs and small batches."
"Taurus is a completely different concept. Rather than having a shuttle table like the Phoenix it has one big bed that we can lay two 12 by 3 m sheets on. The key factor was the ability to process sheets of this size to match the capabilities of our press brakes. While we are working at one end of the machine we can be unloading at the other."
"The ability to add value using the machine’s bevel cutting capabilities was also important. We can cut contours using the 3D cutting head at any angle between plus and minus 45°. This can be used, for example to cut angled holes in the plate for pipe and tube intersections. We also use it for a customer in the bulk handling sector. We make big shafts for them that are made in two halves and we contour both sides of the longitudinal seam where they fit together.”
The large parts we are cutting on Taurus often go into welded fabrications so bevel cutting cuts out a second operation. We can prepare the weld edge directly on the laser.
Reducing carbon footprint
Euskirchen, where Ludwig Esser Metallbau is based, was at the heart of the recent disastrous flooding that hit Germany, so one of the other justifications for moving to fiber lasers was thrown into sharp focus.
“One of our reasons for moving to fiber lasers was the reduction in power consumption, and hence CO2 emissions. It has become even more important since we bought it,” says Mr Esser.
“In recent months the effects of climate change have become more visible – flooding, forest fires, storms – so the decision to make this move was very timely.”
In good hands
Overall, a decisive factor was the ability to buy everything from a single source – with the same programming software and a single point of contact for service and maintenance. A full ERP and CADMAN-JOB integration is scheduled to further optimise the complete production flow.
"As a subcontractor, it is important to us that we have a reputation for reliability in quality and on-time delivery. We have to be flexible in responding to the demands of our customers – which change on a daily basis.
To do that we rely on the support we get from the partners who supply our machines and need to be able to turn to them for advice on new components, materials and technologies. With LVD we feel that we are in good hands.”
