Outlook 2021

Experts in the metalworking industry provided their outlook for the coming year and their insights on how manufacturers should navigate whatever challenges the industry might still have along the way to recovery.

The year 2020 had been an extraordinary one, with the COVID-19 pandemic basically putting the global manufacturing industry on a standstill—at least except those essential industries that have scrambled to create medical equipment such as ventilators, and testing kits, as well as personal protective equipment including face masks and face shields.

The pandemic put into spotlight the agility and resiliency needed in every manufacturing industry, as supply chains get stuck and manufacturers are at a loss as to how to obtain their raw materials and parts. 

Nevertheless, the show must go on. And as vaccines are now being developed, it won’t be long until we see light at the end of this tunnel. In this special feature, experts in the metalworking industry provided their outlook for the coming year and their insights on how manufacturers should navigate whatever challenges the industry might still have along our way to recovery.

Horn Expands Gear Cutting Portfolio

Horn Expands Gear Cutting Portfolio

Paul Horn GmbH is expanding its range of gear cutting products. Horn’s new tool system for milling bevel gear teeth allows the complete machining of bevel gears on universal turn-mill centres. The system was created in cooperation with machine manufacturer INDEX and means that users no longer need any special machines to manufacture gears of this kind. It also allows all functional surfaces to be produced together with the gear teeth in one clamping. This enables high component precision, short lead-times, a very cost-efficient process and short machining times as a result of controlled machining cycles.

With a universal turn-mill centre from INDEX, components with bevel gear teeth can be efficiently and flexibly manufactured, including in small quantities. This also makes the process attractive to small and medium-sized companies that would previously have bought in gears or had them manufactured externally.

For the process, Horn relies on its S276 and S279 double-edged indexable inserts, which are screwed on tangentially. This makes it possible to achieve a stable insert seat, which is particularly important during form milling. The tool does not have to be remeasured after the inserts have been turned around or changed because the inserts are precision-ground on the circumference.

The milling body can be equipped to allow for different numbers of teeth and outer diameters when cutting gears. The process of developing the complete system (cycle, tool and clamping) called for a great deal of expertise on the part of both the machine manufacturer and the tool manufacturer. To implement the process, various types of INDEX machine with a “bevel gear hobbing” cycle are required. Horn offers the milling cutter bodies with the HSK-T40 and HSK-T63 interfaces. The profiles of the inserts are module-dependent and precision-ground.

Horn: When A Millimetre-Sized Component Is Already Considered Large

Horn: When a Millimetre-Sized Component is Already Considered Large

Making a Swiss watch requires micrometre-level of precision. Here’s how Paul Horn GmbH is helping Laubscher Präzision AG in its micro-machining work.

“That’s large by our standards,” says Marco Schneider, department head at Laubscher Präzision AG, as he measures the screw under a microscope. What he is examining actually has a thread size of S 0.6 (a type found in Swiss watches), a thread length of just 0.55 mm and a head diameter of 1.2 mm. This is the kind of component that Laubscher Präzision AG, based in the Swiss town of Täuffelen, is used to handling in its micro-machining work, where it uses tools supplied by Paul Horn GmbH.

Horn developed the µ-Finish tool system to cope with even the smallest of parts: with its outstanding cutting quality, changeovers that achieve precision down to the micrometre level, and low-vibration tool carriers, it is an exceptional piece of equipment.

READ: Harnessing Synergies – Combining Competencies

There are several assemblies that go into the making of a Swiss watch, depending on the exact movement involved—the cogs, winding mechanism, drive mechanism, balance wheel, and motion work are some examples of these. Creating complex movements involves assembling numerous components in the tiniest of spaces, with screws holding everything together. A normal machinist would find producing these screws a hard nut to crack.

And despite their small dimensions, they still need to be synchronously transferred from the main spindle to a collet chuck in the counter spindle when it is time to machine the other side. Rather than callipers or an outside micrometer, it is a microscope with 50x magnification that is used to check the dimensions of these parts. 

Laubscher Präzision relies on the Horn µ-Finish system to produce screws with a thread size of S 0.6 and a thread length of 0.55 mm. It manufactures some 30,000 screws solely of this type every year. Factoring in the many other types that also come off its production line, that adds up to several million screws that Laubscher supplies to the watchmaking industry annually. 

Sharp Tools, Minimum Vibrations

The material used to produce the screws is free-cutting steel in the form of 3 mm diameter bar stock. The process sequence is as follows: facing of the screw head, longitudinal turning of the screw head diameter and of the diameter for the thread, thread cutting and parting off. The µ-Finish tools have a role to play at every stage.

“When you’re precision-machining miniature parts, it’s vital that the tools are extremely sharp and the tool holders produce hardly any vibrations,” explains Alain Kiener, Production Manager at Laubscher. The edge chipping and cutting performance that can be achieved are also essential to the micro-machining process, as any irregularity on the cutting edge will ultimately be reflected on the workpiece.

The Swiss company also specialises in producing micro components for medical technology—where the µ-Finish system once again comes into play, this time in the manufacture of venous plugs. Used for closing off vessels in electromedical applications, these components are pushed through a vein up to the heart via the groin in a minimally invasive surgical procedure. Their front section is then snapped off at the predetermined breaking point, closing off the vessel. 

Boosting Tool Life to 1,000 Recesses

Every year, Laubscher is able to produce between 100,000 and 200,000 of these components, which are made of X5CrNi18-10 (1.4301). The predetermined breaking point has a diameter of 0.1 mm.

“At first, we ground the tool to create the predetermined breaking point profile ourselves. As the cutting quality of the Horn equipment is so good, however, we’ve managed to increase tool life to 1,000 recesses per insert,” says Schneider. When creating recesses up to a diameter of 0.1 mm in solid material, a sharp cutting edge and a vibration-damped tool holder are indispensable.

“Our tool system for micro-machining is also available with heavy metal tool holders, keeping vibrations to a minimum during machining,” says Horn application engineer Phillip Dahlhaus. “In medical technology, a very high surface quality is required. That’s because even tiny irregularities on the component, like grooves and burrs, can be a breeding ground for bacteria.”

The µ-Finish tool system is primarily aimed at micro-machining operators. Based on the S274 system, it features inserts that have been ground with outstanding precision. Every tool undergoes a comprehensive round of inspections during the production process to ensure that its cutting edges deliver these excellent standards of quality. Together with the central clamping screw and the precision-ground circumference of the indexable insert, the tool holder insert seat helps the system to achieve indexability to within microns. This in turn allows the insert to be indexed in the machine without the need to re-measure the centre height or any other dimensions.

In addition to its extensive range of standard profiles, Horn offers custom-made inserts with special designs. “Horn provides high-end tools for a wide range of applications, and solutions for everything from watchmaking screws and medical parts to hydraulic components. We use Horn tools on our Swiss-type lathe, our multi-spindle lathe, and almost everything in between,” says Kiener.

Horn itself is a German tool manufacturer and is represented in Switzerland by the company Dihawag. This partnership between Laubscher, Horn and Dihawag has been in existence for some 25 years, during which time Horn has successfully supplied tools for numerous machining solutions.

“It’s a fantastic partnership. Dihawag and Horn’s representatives are quick to respond to anything relating to our machining tasks, and we know that we can rely on them. We all work together extremely well and it’s amazing how quickly the tools are delivered,” says Kiener.

Horn Unveils New Cutting Insert System

Horn Unveils New Cutting Insert System

Paul Horn GmbH presents the new 32T system for grooving and parting off on Swiss-type lathes and smaller fixed-head lathes. With a precision-sintered grooving insert and central clamping screw, the tool system offers high indexability of the cutting insert and direct entry into the insert seat of the tool carrier. Additionally, there is no need for clamping elements, which may have a detrimental effect on chip flow. The screw head of the clamping bolt does not introduce interfering contours and therefore permits both grooving on a collar and parting off directly at the spindle. The grooving insert can be used as a neutral insert and as both a left-hand and a right-hand insert. The 32T system completes Horn’s portfolio of triple-edge cutting inserts by offering a solution for smaller-scale applications. By adding the new system to its range, the tool manufacturer is responding to customer requests for a triple-edge cutting insert system for Swiss-type lathes and other smaller turning machines, in particular in applications where space is at a premium.

The maximum groove depth of the system is 4 mm with a groove width of 2 mm or 2.5 mm. For grooving operations, the inserts are available with both straight and full radius cutting edges. Horn offers the indexable insert with a 15-degree chamfer for parting off. A cylindrically ground chip breaker geometry makes for reliable chip removal. The tool carrier is designed as a square shank of 10 x 10 mm or 12 x 12 mm cross section. Each version features an internal coolant supply and is available in both left-hand and right-hand designs.

Harnessing Synergies – Combining Competencies

Harnessing Synergies – Combining Competencies

Paul Horn GmbH uses additive manufacturing to produce its own tools, particularly when making prototypes, special tools and tool holders.

Having recognised the advanced possibilities offered by additive manufacturing, Horn is now making these available to its customers and partners as well. To facilitate this step into the future, Horn is creating a new “Additive Manufacturing” production area. This department is closely linked to mechanical production and powder analysis as well as quality assurance.

Horn is using a process called SLM (selective laser melting), a powder bed process that also goes by the name of direct metal laser sintering. In this technique, the metal powder is applied to a lowerable platform in layers and then the relevant area is targeted and melted by the laser. This process is repeated until the required component height has been achieved. The only materials being used by Horn for the time being are aluminium (AlSi10Mg) and stainless steel (1.4404). However, other materials are currently being tested. The maximum build area is 300 x 300 x 300 mm (11.811 x 11.811 x 11.811″).

As Horn keeps all the production stages in-house, it is able to respond to customer requirements directly. The parts are produced in various designs according to customers’ wishes. Horn also helps customers to choose a structure that is compatible with the SLM method and to select appropriate powder-based parameters. Depending on what customers require, Horn can produce everything from unfinished and semi-finished products right through to the finished component. Further advantages are the ability to make use of the available machinery and appropriate measuring equipment.
