Precision and dynamics in modern laser cutting machines – in top form with the right compensating coupling
18.08.2025
Innovative laser cutting technology combines many advantages when processing a wide variety of metals. On the one hand, it ensures clean, burr-free cuts with consistently high quality and, on the other hand, it offers high production speeds with minimal material waste. When cutting contours from a wide range of sheet thicknesses and materials, these automatic cutting machines operate with high dynamics and process reliability. The precise cutting of even highly complex contours requires the optimal interaction of all components involved in the precise drive train. A minimised mass moment of inertia, high torsional stiffness and freedom from play are of utmost importance for the compensating coupling as an integral component in order to support the dynamics and precision of these modern laser cutting machines. The CD A1C composite multi-disc coupling demonstrates its strengths here and scores points with its precision and lightness. The shaft coupling, equipped with lightweight aluminium clamping hubs, has a disc pack made of a high-performance fibre composite material in a unique design. This gives it high torsional stiffness combined with high universal displacement capacity. For automatic laser cutting machines that are designed as modular gantry systems, the torsion-resistant shaft couplings are also available as intermediate shaft couplings with intermediate sleeves in lengths that can be selected according to customer specifications, ensuring precise synchronisation of the cutting processes in these dynamic multi-axis systems.
Torqmax rigid coupling fulfils the high torque requirements in fully automatic bagging systems
04.08.2025
The new home has been proudly purchased, the ink has not yet dried on the purchase contract, and the project is already taking its course. The substance of the house is to be renovated, everything is to be made nicer, cosier and more modern. Warm feet in the bathroom and living room is a top priority and can only be realised by installing underfloor heating. ‘Recognition for those who do things themselves’ is the motto of a large DIY chain. So off we go to the nearest DIY store and head straight for the screed and mortar department. There they are, the large 25 kg or 40 kg paper sacks with our intended contents. A question that is perhaps not of primary importance for the realisation of the project, but how does this powdery product actually get into these weighty, colour-coded containers with gram accuracy? Fully automatic bagging systems ensure highly efficient and precise filling with exact repeat accuracy and without compromising the respective product quality. Various production stages are involved here - from the filling process to the closing of the valve bags, cross bottom bags or gusseted bags and the final palletising process. In such bagging systems, the Torqmax rigid coupling proves to be an ideal partner for the high torque requirements of the systems and for the precise transmission of the drive power. The torsionally rigid shaft coupling has decisive quality features. Honed bores in the version with continuous shaft diameters guarantee the highest surface quality and requirements in terms of dimensional tolerance and shape accuracy. In addition, most of the couplings have a special screw lock that ensures that the high-quality hexagon socket screws used retain their clamping force permanently, even in the event of vibrations, so that the rigid coupling transmits the torque permanently and reliably. If an installation-friendly and time-saving design is required in the respective system, the two-part shell coupling ensures radial installation. For bagging systems for filling food packaging with special hygiene requirements, the Torqmax rigid coupling is available in one-piece and two-piece stainless steel versions. The StepBore version is the solution for systems with different shaft diameters in the drive train.
New size of high-speed coupling for an even wider torque range
14.07.2025
Permanent unrest in the drivetrain, extremely high speeds or highly dynamic start-stop positioning tasks with frequent reversing operation - challenges that can cause slight wrinkles on the forehead when selecting the right compensating coupling. The Speedmax high-speed coupling provides a reassuring remedy. The backlash-free equalising clutch is designed for speeds of up to 42,000 rpm, depending on the size. The high-speed coupling continues to be characterised by the damping of vibrations that occur while maintaining torsional rigidity. An additional size has been added to the range so that the lightweight clutch can be used in an even wider performance range. With the newly added size GSC 27, the product portfolio now includes 10 sizes in a nominal torque range from 1 to 65 Nm.

The Gearmax 5000 bevel gearbox made of stainless steel

From the tree or field to the table - stainless steel bevel gearboxes for the production of fresh food convenience products
We all know that the German Nutrition Society recommends eating five portions of fruit and vegetables a day for a vital and healthy life. But our everyday lives don't actually allow us to pick or harvest these vitamin-rich treats ourselves every day, so we resort to convenience products to save time. Sliced or diced, completely peeled or in strips - these colourful, ready-to-cook and ready-to-eat healthy products smile at us from the supermarket shelves and encourage us to buy and eat them. However, in order to be able to present these fresh-cut products without any loss of freshness and flavour while retaining their vitamins, these products undergo several gentle processing stages and processes, from gentle heat treatment, chopping and portioning to final packaging. The Gearmax 5000 bevel gearbox made of stainless steel is the perfect partner in the drive train of such production processes. Equipped with a housing and shafts made of 1.4401 stainless steel, it not only fulfils the high hygienic requirements, but also ensures efficient right-angled deflection of the drive and guarantees low-noise operation even at the highest speeds. The corrosion-resistant bevel gearbox is provided with lifetime lubrication and is therefore maintenance-free. .
