Bornemann Gewindetechnik GmbH & Co. KG from Delligsen was honored with 1st place in the Foreign Trade Award 2025 at the 20th Lower Saxony Foreign Trade Day. The award was presented personally by Economics Minister Olaf Lies and recognizes the impressive internationalization strategy, innovative strength and sustainable growth of the family business.

Tribological contacts account for around 12% of global energy consumption. Bornemann Gewindetechnik is researching the optimization of trapezoidal threads together with the Institute of Production Engineering and Machine Tools at Leibniz Universität Hannover.

Trapezoidal threaded spindles are ideal for heavy loads and are often used in lifting systems. As part of a cooperation project between the Institute of Production Engineering and Machine Tools (IFW) and the company Bornemann Gewindetechnik, a modification of thread whirling was researched to optimize the tribological properties of threaded spindles. The use of whirled microstructures can reduce friction loss by 25.5% and significantly reduce adhesive wear.

Together with Bornemann Gewindetechnik GmbH & Co. KG to research and optimize parts of thread production in two ZIM cooperation projects. In the TopGewinde project, a method for the defined adjustment of the surface topography was developed in order to increase the efficiency of screw drives with the help of micro-lubrication pockets. In the Quali-Wirb project, a measuring system for process-parallel recording of the thread geometry and surface was developed in order to identify production deviations during the manufacturing process and compensate for them with suitable measures.

Smart threads should make force and torque measurement technology in systems and machines with threaded spindles superfluous – Bornemann shows how this works.

Threaded spindles are a popular design element in mechanical engineering. High-stress threaded spindles, for instance, are particularly prevalent in mechanical lifting jacks and in heavy-duty lifting equipment. The threaded spindles used in these areas are primarily manufactured through a whirling process. Threaded spindles that are produced by rolling processes often have very smooth surfaces that encourage slip-stick and have a negative effect on the service life of the system as a whole.

Whether they are used in plant construction, mechanical engineering or tool manufacturing, in demanding production processes, under water or in outer space: spindles and threads are often subject to extreme requirements. When it comes to thread dimensions, development departments require experienced engineers and technicians from as early as the prototyping stage.

Delligsen/Kaarst, October 2, 2020: Bornemann Gewindetechnik GmbH & Co. KG has won the ife Innovation Award 2020 for its Smart Threads. The presentation of the ife Award 2020 in the batch size 1+ category took place on September 29 at Bornemann’s company headquarters in Delligsen.

The thread profiles on worm gear screw jacks that are subjected to a surface pressure of > 20 N/mm2 under load and that operate at low circumferential speeds require constant lubrication. Bornemann precision threads offer part of the solution.

Threaded spindles and nuts have been a central part of modern life since the dawn of industrialisation. A startling fact: at present, it is practically impossible to predict their durability and wear, which is of critical importance for securing your investments. Introducing the new TriboLife thread testing system: it can rapidly reproduce wear through experimental testing, rendering expensive endurance test stands largely redundant.

Thread manufacturing processes can initially be divided into three main groups: Primary forming. Forming, cutting. Primary forming is mainly used for plastic screws and nuts by means of injection molding.

In petrochemical plants, power plants and other industrial installations, control valves precisely regulate the movement of gases and liquids. Leaking valves are one of the single greatest impediments to the efficiency of industrial processes.

In large offshore winches, the reverse threaded spindles or diamond screws of Bornemann Gewindetechnik play a critical role in winding expensive special cables. The diamond screws are used in hoisting winches in spooling equipment known as level winders for neatly winding layer upon layer of extremely heavy cables that are often thousands of metres long.

Bornemann Gewindetechnik GmbH & Co. KG, based in Delligsen, Lower Saxony, has been producing threaded spindles and screw conveyors for more than 25 years. One of their main products is ready-to-install trapezoidal spindle drives for heavy-duty lifting gear, as used to lift rail vehicles. Constant lubrication of the load-bearing flanks of the thread profiles is essential for spindle lift drives, as insufficient lubrication can lead to increased wear and overheating as well as the socalled stick-slip effect.

The expansion of a high speed rail network is progressing in europe. The french railway company SNCF is about to develop its TGV (high speed trains) trains in a new generation, just as the German Deutsche Bahn is doing. even a private competition is rising in the ring of italy against the “frecce Rosse“ and from year 2014 there will be a high speed link from Cologne to London. Also Russia plans to develop a network of high speed train services for the 2018 fifA World Cup such as 300 to 400 km/h high speed trains from Moscow to st petersburg, to nizhny novgorod and to Kazan, with a possible extension to Yekaterinburg

Many of the threads used in medical technology are manufactured using the whirling process. In in-vitro diagnostic applications, screws and threaded spindles are used as machine parts in liquid handling systems or measuring instruments.

Bornemann Gewindetechnik GmbH & Co KG in Delligsen has delivered a hitherto unique custom-made product: an aluminum spindle over 22 m long with a diameter of 200 mm. It consists of several segments and was delivered to a globally active company in the field of conveyor technology.

Bornemann-Gewindetechnik has been producing threaded spindles and nuts for almost all branches of industry for more than 25 years. The main focus of production is the manufacture of ready-to-install trapezoidal screw drives, consisting of spindles and nut sets for heavy-duty lifting systems, such as those used in lifting systems for rail vehicles, in theater and stage construction and in special machine construction.

If screw jacks no longer work, this may be due to the surface quality of the spindles, contamination, the installation position or, in particular, the choice of lubricant – says Hans Gereke-Bornemann, Managing Director of Bornemann Gewindetechnik, who also has a solution for this.

Bornemann-Gewindetechnik develops and manufactures threaded spindles for high loads. They are used in particular in lifting technology and hydraulic steel construction.
