Our state-of-the-art systems enable precise laser drilling with an impressive peak pulse power of up to 50 kW. Thanks to advanced pulse lasers and powerful solid-state lasers, such as rod and fibre lasers as well as ultrashort pulse lasers, we offer tailor-made solutions for your specific requirements.
With generous traverse paths of up to 2100 mm x 380 mm x 400 mm, we open up a wide range of application possibilities in the field of laser drilling. Our range of services also includes the processing of continuous foils and the integration of automated assembly. Rely on BBW Lasertechnik for maximum precision and efficiency in your laser drilling projects.
We select the optimum laser drilling process according to the specific requirements of our customers. At BBW Lasertechnik, we combine state-of-the-art technologies with decades of experience to find the perfect solution for your drilling requirements.
With single-pulse drilling, a single hole is created with each laser pulse. Typical pulse durations are in the range of 10 µs to 1 ms. This process enables hole diameters from a few hundredths of a millimetre to around 1 mm and achieves aspect ratios of up to 20:1. Productivity depends heavily on the pulse repetition rate, which defines how many holes can be produced per second. Several hundred holes per second are possible. Single pulse drilling is an ideal process for filters or screens where a large number of holes are required.
Percussion drilling is characterised by the fact that laser pulses repeatedly hit the same area of the material. This enables greater drilling depths with smaller diameters, typically from 0.01 mm to 1.5 mm at depths of up to 15 mm and aspect ratios of up to 200:1. To minimise heat accumulation and maximise drilling quality, the pulses can be applied to different holes in succession. Percussion drilling is particularly suitable for applications such as ventilation, cooling and lubrication holes.
In helical and trepanning drilling, the laser beam is moved in a circle just inside the desired hole diameter, which allows the material removal to be precisely controlled. The hole diameter is determined by the circular path of the beam, the beam diameter and the interactions with the material. These processes use scanner optics or specialised helical and trepanning optics to realise the relative movement between the laser and the workpiece. Trepanning drilling is a combination of percussion and helical drilling and is suitable for applications that require high precision.
Micro drilling refers to the production of particularly small holes in the micrometre range with maximum accuracy. At BBW Lasertechnik, we define micro drilling as holes up to a diameter of 150 µm and with tolerances of +/-10 µm. For holes larger than 150 µm and with tolerances of +/-50 µm, we speak of precision drilling. We classify holes smaller than 1 mm as fine holes.
Our core expertise lies in laser drilling and the processing of materials that require the highest precision in the micrometre range. At BBW Lasertechnik, we specialise in meeting your individual requirements with state-of-the-art laser technology. Whether it's fine tube processing, micro-drilling or the production of individual parts for complex assemblies - we offer customised solutions that exceed your expectations.
In fine tube processing, we rely on the latest laser drilling processes to realise even the smallest holes with maximum precision and reliability. We can realise the finest openings in thin-walled tubes. These applications are particularly in demand in industries such as medical technology, electronics and mechanical engineering.
With micro-drilling, we are able to produce the smallest holes in the micrometre range with exact tolerances. Thanks to our highly developed laser systems, we are able to achieve precise and consistent results even with challenging materials such as ceramics, hardened steel or titanium. This accuracy is crucial for applications where the quality and dimensional accuracy of the holes are critical.
We guarantee consistently high quality and precision in the production of individual parts for assemblies. Our experienced team works closely with you to ensure that every component is manufactured exactly to your specifications. It doesn't matter whether it's a prototype or series production - our advanced laser drilling technologies ensure optimum results for every application.
If you are looking for precision, quality and versatility for your laser drilling requirements, BBW Lasertechnik is your reliable partner. We use state-of-the-art laser technologies to realise your projects efficiently and to the highest quality. Our team of experienced professionals is here to help you turn your vision into reality.
Contact us today to realise your projects with our expertise and advanced laser solutions. With BBW Lasertechnik, your drilling requirements are in the best hands.
Our high-precision laser drilling technology is used in a wide range of industries and fulfils even the most demanding requirements. At BBW Lasertechnik, we specialise in specific applications such as the laser drilling of filters and screens for the automotive industry, the production of vent holes for injection moulding tools and tube processing. In addition, we offer complementary services such as chemical pickling, manual reworking and mechanical finishing. This enables us to ensure that every job fulfils the highest quality standards.
For the production of filters, we rely on single-pulse drilling as well as micro-drilling and trepanning. These processes enable us to create extremely fine holes in filter materials used in the automotive industry, medical technology and other sectors. The laser drilling technology guarantees a high throughput rate and precise dimensional accuracy.
The production of sieves requires maximum precision to ensure a uniform hole structure. Our laser systems, particularly in single-pulse drilling, micro-drilling and trepanning, enable the production of sieves with perfectly defined openings. The sieves we produce are used in various industries, for example for separating particles or filtering liquids.
Nozzles that need to produce uniform liquid or gas flows benefit from our laser drilling technology. We offer customised solutions for the production of nozzles with extremely small and precise bores, which are essential for applications in the automotive, aerospace, chemical and pharmaceutical industries.
Our expertise in laser drilling also enables the processing of drums. These are used in the textile industry, in paper mills or in other production processes. With our technology, we can drill precise and evenly distributed holes that help to optimise processes and increase efficiency.
In addition to laser drilling technology, we offer the following additional services to ensure that your products meet the highest quality standards:
Laser drilling is a high-resolution process for producing circular cylindrical or conical inner surfaces in materials, whereby the depth of the hole can be equal to or greater than its diameter. Unlike conventional drilling, laser drilling is a wear-free process. The hole is drilled through direct interaction between the laser beam and the material to be processed.
During laser drilling, the energy of the laser beam is absorbed by the material and the high energy density leads to melting and partial vaporisation of the material, whereby localised heating in the edge area must be taken into account.
The physical principles involved in laser drilling are similar to those of other ablative processes. The decisive factor here is the selection of the correct parameters such as pulse length and repetition frequency, as pulsed laser radiation is typically used in laser drilling. These parameters influence the drilling process.
To summarise, laser drilling is a precise, contactless and extremely versatile process. It is particularly suitable for materials that are difficult to process using traditional methods.
Laser drilling is particularly useful when conventional drilling methods reach their limits due to material hardness or brittleness. Materials such as ceramics or hardened steels, which are difficult to machine using traditional methods, can be drilled efficiently and accurately using laser drilling.
We have the know-how and the technology to develop the optimum process strategy and the right process parameters for your requirements. You can rely on our expertise to successfully master even the most challenging drilling tasks.
