Two open plants, Six Specialist Presentations and over 60 Exhibits: HORN Technology Days 2025
From 14th to 16th May 2025, Paul Horn GmbH opened its doors for the ninth time to around 3,300 visitors from a total of 33 countries.
Mastering processes in theory and practice: Visitors were able to expand their knowledge during six specialist presentations combined with live machining. Topics included machining aluminium with PCD tools, machining small bores, grooving, parting off, form grooving and turn-milling as a solution for long-chipping materials. Those who wanted to delve even deeper were able to take part in moderated demonstrations in three live production areas. In addition, two presentations focused on Horn’s internal product configuration and the integration of AI. Visitors were able to see, test and experience these on-site.
From a pasta machine and a braking system for an intercity express train to the combustion chamber of an Ariane engine: throughout the production area, the tool manufacturer displayed over 60 impressive exhibits that had been machined using Horn tools. In all, 20 demo components were machined live on various machines. In addition to extensive freedom of movement around the open production facilities in the two plants at the Tübingen site, visitors were given an insight into the process from powder to the finished blank for an insert at a special exhibition organized by HORN Hartstoffe GmbH.
Two final presentations from the TransKI and MetaLearn projects funded by the Federal Ministry of Education and Research (BMBF) also took place as part of the Horn Technology Days. A total of 50 partner companies rounded off the event.
Markus Horn, Managing Director of Paul Horn GmbH, summarizes: “The Horn Technology Days 2025 were a complete success. The feedback from our guests not only confirmed this, but more than exceeded our expectations. We are already looking forward to 2027, when it will be time to welcome visitors again to the Horn Technology Days.”
Horn Technology Days is an Open House Event where customers from all over the world are invited to Tubingen to see for themselves what lies behind the scenes. Please contact us if you would like to be a part of the next Technology Days.
Engis® ElectroMill® Diamond Milling Tool – One Tool, Endless Possibilities
The flat machining of bi‐metal surfaces or milling applications involving an interrupted cut can present daunting challenges to PCD or carbide milling cutters. The inserts may chip during the milling process, resulting in high machining costs and elevated levels of sub‐standard or rejected parts. The Engis ElectroMill is designed to produce high quality, flat milled surfaces, even if an interrupted cut is present or multiple materials need to be machined simultaneously. It effectively replaces expensive, complex cutters in high volume applications such as high strength alloys, stainless steel, ceramics, cast iron, fiberglass pipe, composites and aluminum.
Features and benefits include high stock removal rates, stress-free cutting action, extended tool life, industry standard adapter mountings and milling cutting dimensions. Additionally, superabrasives deliver longer tool life than conventional milling technology.
Combined with high pressure coolant, the ElectroMill can machine several materials to an extremely accurate value of flatness with very low tooling costs. On cast iron, this hybrid tool can achieve flatness of up to 20 µm and surface finishes as smooth as 8 Ra over a single continuous length of 25,000 inches. In some cases, customers have been able to reduce scrap and reworks significantly; this contributes to increased productivity and an improved bottom line.
The turned parts manufacturer Schauerte machines threads in high-alloy, corrosion-resistant Cr-Ni steel much more economically with GFM Shark thread milling cutters from Johs. Boss GmbH & Co. KG, brand JBO.
Wilhelm Schauerte GmbH & Co. KG in Lennestadt employs 140 skilled workers to manufacture turned parts for the automotive industry, general mechanical and apparatus engineering and sanitary engineering. Among other things, tapered Whitworth pipe threads Rp ½″ (14 threads per inch) have to be inserted into components made from the corrosion-resistant, high-alloy steel X2CrNiMo17-12-2 (material no. 1.4404) over a thread length of around 15 mm. Rotary transfer machines produce these components in large series. In the past, the contract manufacturers in Lennestadt used thread milling cutters from different tool manufacturers to mill the threads. However, the tool life and tool life proved to be insufficient. After just under 12,000 threads, the tools were worn out and had to be replaced. This caused frequent downtimes of the highly productive rotary transfer machines.
Optimized Cutting Geometry
The contract manufacturers in Lennestadt now machine much better and more economically with GFM Shark thread milling cutters (D16x41xG14 IK) from JBO (Johs. Boss GmbH & Co. KG). The tools are held in TENDO Turn hydraulic clamping systems (Schunk). The threads are cooled and lubricated with oil during milling.
The cutting edge geometries of the GFM Shark thread milling cutters are carefully matched to hard, corrosion-resistant steel alloys and now ensure significantly longer tool life. The thread milling cutters machine around 30,000 threads at a cutting speed of Vc=100 m/min and a feed per tooth of fz=0.08 mm up to the wear limit. This means that they achieve almost three times the tool life. On the other hand, they reduce the possible cycle time, as they work more productively than the previously used threading tools.
GFM Shark Thread Milling Cutters from JBO with specially optimized cutting edge geometries achieve three to six times the tool life. The picture shows a thread milling cutter with worn cutting edges.
Multiple Use
A special feature of the thread milling cutters from JBO ensures that the tools also optimize efficiency when milling threads in components made from high-alloy steels. They have a total usable cutting edge length of 41 mm. This means that they are only partially stressed when milling threads over 15 mm in length. They can therefore be shortened (halved) by around 20 mm (once the wear limit has been reached on the utilized part of the cutting edges). With the remaining part of the usable cutting edges, they then machine a further 30,000 threads until the wear limit is reached. This means that the production technicians at contract manufacturer Schauerte can use GFM Shark thread milling cutters from JBO for a total of 60,000 and sometimes even up to 80,000 threads on their rotary transfer machines. As specialists at Schauerte confirm, this is done reliably and with process security. With these six times the tool life – compared to conventional thread milling cutters in the past – the GFM Shark thread milling cutters from JBO prove that they can produce much more economically with high process reliability. The contract manufacturer in Lennestadt can now reduce its demand and procurement for thread milling cutters to around a third or even a sixth of the quantities previously required.

Nickel-based alloys, titanium, cobalt-chrome: Reliable machining of these problematic materials requires a high level of expertise on the part of the user. If the workpieces also require high surface quality, the use of specialized tools is essential. HORN addresses this need with a CBN tool system that is unique on the market. Geometries specially developed for finishing ensure high surface quality, tight tolerances and high process reliability when machining the material groups P, K and S. Moreover, HORN is pushing the boundaries of machining speed with this system.
In operation, the tools achieve speeds of 350 m/min (1,148 ft/min) when cutting Inconel and 300 m/min (984 ft/min) when cutting titanium alloys, for example. The tools produce surfaces with an almost mirror-like finish. The combination of cutting material, quality of the tool edge grinding, coating and coolant supply enables the high performance. The reliable process is enhanced by the linear wear behavior of the CBN cutting material. Wear rate is therefore predictable. The finishing system is available as standard in numerous HORN tool systems. In addition to various ISO inserts, HORN offers CBN inserts for the Supermini, Mini, 229 and 315 systems, as well as for the DTS milling system.
