HORN: AMB 2026

 

HORN AMB 2026

Horn brings the Shop Floor to AMB 2026

When AMB 2026 opens its doors in Stuttgart, the international metalworking industry will once again take centre stage. In even-numbered years, the exhibition ranks among the industry’s most important meeting places. It brings together products, technologies, services, training and personal exchange. For users, manufacturers and decision-makers, it offers a concise overview of the latest developments in machining and manufacturing technology.

Paul Horn GmbH is using the AMB not only to showcase precision tools, but also to demonstrate them in real-world machining scenarios. The company is exhibiting in Hall 1, Stand J10, across an area of around 500 square metres. Three machines in operation demonstrate HORN’s expertise. Standard products, bespoke solutions and innovations are all featured. HORN brings the shop floor to the exhibition – visible, tangible and practical.

S274 tool system

A new product at the stand is the expansion of the S274 tool system . Horn is further expanding the system with new sintered chip-forming geometries for parting-off and turning. The new types improve chip control, increase process reliability and support cost-effective machining on Swiss-type lathes. For grooving and parting off, Horn is supplementing the precision-sintered chip-forming geometry .1A with narrow grooving widths of 0.8 mm and 0.6 mm. This enables users to reduce material loss whilst ensuring reliable chip formation.

The inserts are available as type RS274 and as the RE274 type with a pressed-in threaded insert for RH274 clamping holders. Horn offers them in the carbide grades TH35 and IG35. In addition, the new chip-forming geometries .NF and .PR have been introduced. The .NF geometry is designed for grooving and sliding-head turning, whilst the .PR geometry is designed for reverse turning. Both geometries cover feed rates ranging from 0.02 to 0.1 mm/rev and are suitable for a variety of materials.

Defence and Aerospace

Alongside these product solutions, AMB 2026 will feature further specialist themes, including Defence and Aerospace . The Saturday of the trade fair also plays a special role for HORN: the company is taking part in the parent-child rally. The aim is to inspire young people to take an interest in mechanical engineering and manufacturing technology and to make it easier for them to gain access to industrial practice.

“In even-numbered years, the AMB in Stuttgart is Europe’s leading trade fair for metal cutting,” says Markus Horn, Managing Director of Paul Horn GmbH. “I am convinced that the trip to Stuttgart is well worth it and that our customers and guests will take home clear added value. Solutions, innovations and dialogue on an equal footing form the basis for this. Please visit us in Hall 1, stand J10. We look forward to seeing you.”

 

 

HORN: Processing of Lead Free Alloys

Specially developed geometries provide a high degree of process reliability when machining lead-free materials

The alloying of lead in metallic materials has a positive effect on the machining process. Due to the EU’s REACH and ROHS regulations, the time of these easy-to-machine materials is over in many applications. However, reliable machining must still be possible in the future. With its broad tool portfolio, Paul Horn GmbH has a suitable solution for almost every application.

The main problem when machining lead-free alloys, be it brass or free-cutting steel, is the lack of reliable chip breaking. But what exactly is the effect of the alloy component lead, which is toxic to humans? During machining, the soft metal creates predetermined breaking points in the alloy, as lead forms small nests or inclusions in the alloy structure. These ensure good chip breaking and low cutting forces during machining. Furthermore, the heavy metal acts like a lubricating film, which has a positive effect on tool wear.

The changeover was initially a challenge. The good cutting properties of the lead-alloyed materials were lost. In addition, the wear on the cutting edge increased significantly. This was remedied by grooving and longitudinal turning with chip-breaking geometries from the steel sector and special laser-cut geometries. Extensive investigations show that chip-breaking geometries for steels with medium strength in particular work very well with lead-free materials.

With the new Type 105 Supermini, Horn has developed a universal boring tool with sintered chip form geometry

During internal boring, adapted geometries also ensure reliable chip breaking. One of the biggest challenges in internal machining is long chips. These often occur during bore machining. They wrap around the tool, clog bores or, in the worst case, lead to tool breakage. Previously, specially lasered or ground chip form geometries were used for this purpose. However, this was associated with a corresponding cost factor for the cutting insert. With the new Type 105 Supermini and the Type Mini with I geometry, Horn has succeeded in developing universal boring tools with sintered chip form geometry. The tools offer high process reliability in use thanks to good chip control. The cutting edge geometry extends far into the corner radius of the insert. This ensures chip control even with small infeeds. The geometry can be used universally for different material groups and is suitable for internal, face, copy and reverse turning.

HORN: New Generation Ball Track Milling

New Horn KX System

New generation of Ball Nose Endmills

With the new KX system, HORN is launching a high-performance solution for the economical and reliable machining of ball bearing tracks. HORN developed the system specifically to meet the increasing demands for precision, flexibility and productivity in the production of constant velocity joints. The system covers a wide range of components and offers three sizes. Flexible machining strategies enable both soft and hard machining – from roughing and chamfering to finish milling. Customers can adapt the strategy precisely to their process requirements, ensuring a high level of cost-effectiveness.

With the KX system, HORN has considerably increased the performance of the tool system. Soft-cutting cutting heads with defined edge preparations enhance process reliability. Precise internal coolant positioning and a newly developed interface improve rigidity. Practical benchmarks confirm the performance: Users significantly increase cutting values and noticeably reduce cycle times. Depending on the component, they shorten the machining time by several seconds per workpiece and sustainably increase productivity.

Constant velocity joints are used in every car and are also known as homokinetic joints. Their purpose is to transmit uniform torque and angular speed from the drive shaft to a second shaft mounted at an angle to it. In other words, constant velocity joints transmit rotary motion uniformly to the next shaft. The joints are most widely used in vehicle construction for power transmission from the gearbox to the drive wheels. Constant velocity joints can transmit rotational movements at an angle of up to 50 degrees. In addition to fixed ball joints, sliding constant velocity joints are also used. They allow not only angular movement, but also axial movement so that power transmission is not interrupted when steering or during movement of the suspension.

At the heart of a homokinetic joint are the balls, which roll in precisely milled tracks. The ball tracks have a very tight manufacturing tolerance and a high surface finish is essential. The tight tolerances and the manufacturing quality determine how long the service life of the joints will be. The form tolerances of the parameters are to within microns.
