NEW BUILDING GEAR CUTTING PRODUCTS IN THE USA ABOUT US

Tool by tool – Tooth by tooth 2020 innovations The HORN Group invests The HORN Group expands internationally DEAR READERS,

The last few months have seen us living in extraordinary times that are shrouded in uncertainty and insecurity, and dominated by cautiousness. The measures implemented were – and remain – only right and proper. But that now makes it all the more important for us to turn our attention towards the future. COVID-19 has had an enormous impact on industry and many other sectors, with a good number of firms having been forced into adopting reduced working hours or, in some cases, even more extensive measures. In spite of everything, we are arguing for the quickest possible return to some semblance of normality.

Our ability to supply our products has not been affected. Extensive pre- ventative measures have been put in place to ensure that your contacts can still be reached via the usual channels. Registered customers can also get hold of our products by visiting our online shop at eshop.phorn.de.

This edition of “world of tools” covers a wide range of topics. As well as providing insights into the international activities of the HORN Group, we also showcase our capabilities in the area of gear production and illustrate everything a tool has to go through at our end before it is used by you. Our innovations are also featured here as usual, even though the major AMB (Stuttgart) and IMTS (Chicago) trade fairs could not take place in September in the normal format.

With an eye on the future, we hope this edition provides you with some interesting new perspectives and wish you all the very best for the days that lie ahead.

It is only because of these This got the key people at Collins interested in how systems that this extremely complex technology can be used. they could use it themselves and influenced their Collins Aerospace, based in Figeac (France), has been relying decisions when selecting new machining processes. on this highly productive technique since 2019.

Technical support for the project was provided by engineer Emmanuel Gervais. He is the primary contact at HORN when it comes to machining critical aerospace components and he also supports the development of new tool concepts by providing valuable expertise and experi- ence. Unsurprisingly, Gervais is based in the area of south-west France around Toulouse – the epicentre of the European aerospace industry.

An interview with Lothar Horn, Managing Director of Paul Horn GmbH and son of company founder Paul Horn, on the HORN Group’s journey to internationalisation.

When is it right to create a new HORN Group com- pany and when is it is more appropriate to work with sales agencies? We have a presence in more than 70 countries world- wide – mostly via trading partners. When choosing which companies to work with, we always look for those that embody our philosophy of “customer fo- cus, quality and speed” and that know the customers and the market inside out. A prime example of this is DIHAWAG, our representative in Switzerland. We have enjoyed an equal partnership with them for almost five decades and are constantly taking the relationship further. When you notice a change in the nature of a partnership or the requirements of the market over the medium to long term, you sometimes end up reassessing the situation and establishing a presence of your own. The key priority is being able Mr Horn, you joined the company back in 1991. to serve customers in the best possible way.

As a subsidiary, HORN USA has found its greatest successes by mimicking the positive examples of its parent company. Just as Paul Horn GmbH has increased its manufacturing capacity for faster delivery and to better meet its customers’ requirements, HORN USA has also kept its finger on the pulse of customer needs while looking towards expansion.

Strategic growth has long been a part of the success of Paul Horn GmbH. Since its founding in 1969, the company established its reputation for innovative solutions and quality workmanship in the production of high precision grooving, side turning, and slot milling tools for demanding metalworking users. While supplying customers with the finest cutting tool products has always been at the forefront of company culture, progress has been measured by company BY 1993, PAUL HORN expansion, whether through product development, company GMBH HAD BEGUN TO size, or geographic reach. By 1993, Paul Horn GmbH had begun opening subsidiaries EXPAND SALES. to expand sales, manufacturing, and support capabilities to international markets. One of those subsidiaries, HORN USA Inc., was incorporated in 1997, beginning business operations in a modest office suite location in Franklin, Tennessee, and taking advantage of the 1998 edition of the International Manufacturing Technology Show to announce its official opening. Product specialists and sales managers traveled from Germany to Chicago to support their new colleagues in the United States during the exhibition. The trade show, promoted as the largest manufac- turing trade show in North America, proved to be the prime location to introduce HORN’s precision tools and technical capabilities to the region. | ABOUT US | 26 Andreas Vollmer Duane Drape President National Sales Manager

The HORN Group directly entered the Turkish market on 1st April 2020 by opening a sales company in the Republic of Turkey. Prior to that, the precision tools had been distributed from Tübingen via a trade partner based in the republic. To better unlock the potential of the Turkish market and accommodate the requirements of customers there, HORN decided that it should establish a presence of its own in the country in accordance with the motto “Think globally, act locally”.

THE MOTTO HERE IS: “THINK GLOBALLY, ACT LOCALLY”.

From now on, the same objectives that have been set by HORN for Germany and many other countries are to be pursued in Turkey: a technological edge for users coupled with sustainable customer rela- tionships. Every country is different and so HORN allows a lot of leeway at the regional level to accom- modate the local conditions that apply in each case. The new sales office is located in Istanbul and has an initial floor space of 450 m² (4,844 square feet). Bahadir Öge, one of the managing directors at HORN Turkey has the following to say: “The country offers excellent growth opportunities for our products. I am convinced that we will be able to achieve our medium and long-term aims, and that we will be able to consolidate our firm position as a technology leader in Turkey as well.”

Turkey covers an area of 783,562 km² (302,535 square miles) and had a population of approximately 83 mil- lion in 2019. Despite the fact that the machine sector has been in decline since 2019, the medium-term Bahadir Öge, one of the managing directors of governmental outlook was positive. According to the HORN Turkey. | ABOUT US | 32 The HORN product range offers an extensive array of tool solutions to accommodate the requirements of customers in Turkey.

VDMA (the German Mechanical Engineering Industry Association), real GDP was originally projected to grow annually by five per cent up to 2022. However, it remains unclear how this will be affected by the coronavirus crisis, not just in Turkey but across the global economy. Nevertheless, Öge remains confi- dent adding: “It is precisely at times like this that innovative tool solutions are required to improve and optimise machining processes in a purposeful way without having to invest in a new machine right away”.

The philosophy of Paul Horn, founder of Paul Horn GmbH, was this: “The only way to achieve the best possible results is to control the entire process chain for my tools!” This idea is now being consistently pursued by his son, Lothar Horn, and his grandson, Markus Horn, as the basis for the company’s success.

The manufacturing process for an insert starts with mix- ing and preparing carbide Given the short lead times for which HORN is re- alloys in powder form. nowned, the only way to manage the production volume it has built up over more than 50 years is to use highly automated – the degree of automation is currently 97 per cent – and very flexible processes. Among other things, this means having to contin- uously adapt increasingly complex manufacturing processes to the latest technical, logistical and organisational advances and, in turn, involves mas- tering different process chains and technologies from development all the way through to delivery. | ABOUT US | 36 Axial press systems make it possible to manufacture complex inserts extremely cost-effectively.

alloys in powder form, pressing aids and additives – to create mixtures that are ready for pressing. The carbide alloys are supplied in grain sizes of 0.6 (0.00002") to 6 µm (0.00024") and in batches with a weight of approx. 1,000 kg (2,205 lbs) for uniformity in the powder composition. Maximum precision is required during the weighing and dosing of important pressing aids and additives for subsequent shaping, as even slight differences (the pressing aids are weighed out with a tolerance of 0.01 g (0.00002 lbs)) can significantly change the final product. The mix- tures for pressing are then prepared for the various shaping processes in vertical carousel storage areas in accordance with the first-in/first-out principle.

Direct and indirect shaping processes A mixture for pressing is turned into inserts or tool shanks using direct and indirect shaping methods. Extrusion and isostatic presses are used for indirect shaping. The green compacts produced in this way are pre-sintered, then machined and final-sintered. In the case of direct shaping (axial pressing or injec- tion moulding), the only downstream processes are pre-sintering and then HIP (hot isostatic pressing) sintering.

39 | ABOUT US THE MINI SYSTEM IN ACTION SPECIAL TOOLS FOR DIFFICULT RECESSES

“We have been relying on tools from Paul Horn GmbH for more than 30 years. The solution to our latest problem has once again reminded us of why”, explains Roland Burghart, who is in charge of turning at the Donaueschingen plant of SICK STEGMANN GmbH. The problem related to the creation of axial recesses in intricate sensor components made from titanium. HORN solved the task through a combination of measures, which included various special versions of its Mini system. Working in conjunction with HORN technical consultant Karl Schonhardt, the HORN designers devised a cut distribution for the difficult machining task. The quality requirements for the components are extremely demanding.

The workpieces are installed inside highly sensitive gas flow measurement sensors. At the heart of these measuring units lie the oscillating transducers. The sensors are used, for exam- ple, in gas pipelines, for measuring flare gas, for vapour flow A few members of the trans- measurement, as well as in biogas plants. Sensor technology ducer part family. from SICK is intended to protect people from accidents, avoid damage to the environment and supply accurate data. For this reason, the company demands a high standard of quality from its products. This starts with the individual parts and compo- nents. Tight tolerances, high surface quality and difficult to machine materials are all part of everyday life for the SICK employees working in the area of CNC manufacturing.

To ensure high corrosion resist- THE TRANSDUCERS LIE AT THE ance, the engineers from SICK selected the titanium alloy Ti 6Al- HEART OF THE MEASURING UNITS. 4V (Grade 5) for the transducers. This alloy accounts for approximately 50 per cent of worldwide demand for titanium. And that is because it offers a good bal- ance between high strength and low density. The mechanical properties of this titanium alloy are superior to those of pure titanium. One of the problems it poses during machining is that it has a tendency to work harden. When the friction becomes excessive due to the feed rate of the cutting edge being too low, work hardening of the material is induced. This shortens the life of the tools dramatically. When turning and milling titanium, it is vital to have sharp cutting edges, the right cutting parameters and the appropriate tool coating in order for the machining of this material to be productive. | THE MINI SYSTEM IN ACTION IN SYSTEM MINI THE | 40 For parting off, SICK relies on grooving systems from HORN.

Large part quantities require well- conceived tool solutions “The machining of titanium alloys no longer poses any major challenges for experienced machinists – when the ma- chining operations are straightforward”, says Schonhardt. However, in this case, the axial recesses and thread on the transducers called for an appropriate tool design and an intelligent machin- ing strategy. Burghart’s team produces various versions of the transducer in diameters ranging from 4 mm (0.157") to 12 mm (0.472"). “To accommodate different applications, we have several variants of the parts, all of which we produce here at the Donaueschingen plant. The members of the transducer part family are manufactured around the clock on a three-shift system. That is another reason why having a produc- tive tool system was so important to us”, explains Burghart. | THE MINI SYSTEM IN ACTION IN SYSTEM MINI THE | 41 42 | THE MINI SYSTEM IN ACTION PROCESS TO BE IMPLEMENTED.
