As a result of the design of the Supermini, clamping is not carried out via the lateral surface of the cutting insert but via a clamping wedge on the face.  This results in a greater holding force on the insert and thus high rigidity of the entire system.

It's that time of year for IMTS!

​Here's a preview of some of the products that are going to be featured during the International Manufacturing Technology Show September 12-17.  You can see all of these new products and talk to the manufacturers in the Tooling & Workholding Systems Pavilion in the West Building Level 3. 

Supermini Set. Horn USA is featuring the Supermini tool holder system with face clamping as a set, in response to customer requests for different tooling system heights. With this holder variant, clamping is not carried out via the lateral surface of the cutting insert but via a clamping wedge on the face. This results in a greater holding force on the insert and thus high rigidity of the entire system. This increases repeatability when changing the insert and provides better utilization of the available space. This is a big time saver on Swiss-type lathes, as the user can change the cutting insert without removing the tool holder.

New carbide grades for system DAH8 - Horn USA is expanding its range of carbide grades for its DAH milling system to enable its use for machining a wider range of materials. The new grades SC6A and IG6B complement the tool system for high-feed milling. The SC6A grade is suitable for machining the ISO M material group, as well as ISO S materials as a secondary application. Horn has developed the IG6B grade for machining the ISO P group, while it is also suitable as a multipurpose grade for other material groups.

If you would like to learn more about any of these products or to see a demonstration, get in contact with us and we'll set up some time with you to visit your shop!

Horn USA has introduced the new DR-Large modular reaming system for use in the machining of large bores.

Horn USA recently expanded its circular milling system 304 with new thread milling inserts to perform in diameters of 8 mm (.315”). ​

The precision tools are available as partial and full-profile versions for the production of threads by helical interpolation.  Triple-edged inserts in the 304 system already exist for groove milling, finish boring, and chamfering.  

The new threading inserts spin on diameter 7.7 mm (.303”).  Vibration dampening carbide shanks with integral through coolant ports make the system versatile and easy to use. 

The HORN circular milling system offers users a host of process advantages.  It is fast, reliable, and produces good surface finishes. 

During the machining process, the tool plunges into the material either at an angle or almost horizontally and is then driven on a helical path.  Threads can be manufactured at a highly reproduceable level of consistent quality. 

Circular interpolation has a wide range of applications and can be more economical when strategically applied when machining steel, special steels, titanium, and alloys. 

HORN’s circular milling tools are engineered for precision machining of grooves, threads, t-slots, profile milling and other circular interpolation processes.

Paul Horn GmbH is responding to the requirements of users with their product line expansion to the tool range for slot milling and slot cutting, .

​Horn now offers the cutter body of the M310 milling system with an internal coolant supply. This increases the service life of the indexable inserts and therefore reduces tool costs. The internal coolant supply also allows a higher level of precision when slot milling as no heat is transferred from the cutting zone into the component.

​What’s more, the flushing action of the coolant, combined with the geometry of the cutting edges, prevents chip jamming in deep grooves.

Horn offers two types of milling and slotting cutter. The screw-in milling cutter is available in diameters from 50 mm (1.969") to 63 mm (2.480") with widths from 3 mm (0.118") to 5 mm (0.197").

As an arbour milling cutter, the main bodies are available with diameters from 63 mm (2.480") to 160 mm (6.300"). The widths are also between 3 mm (0.118") and 5 mm (0.197"). The three-edged S310 carbide inserts are bolted on the left and right of the main body and therefore ensure a good distribution of the cutting forces.

In addition to further geometries for processing different materials, Horn is introducing inserts with a geometry for milling aluminium alloys.

As well as expanding the M310 system, Horn is rounding off the range of the M101 and M383 milling systems.

For the M101 tool, S101 inserts are available from stock with a width of 2.5 mm (0.098").

What’s more, new inserts with an 8-degree lead angle are available especially for slot cutting. For the 383 system, HORN is expanding the range of bodies with diameters of 125 mm (4.921") and 160 mm (6.300").

In February of last year we posted Horn USA's Construction Cam. If you check it now, you'll see the new USA Headquarters.

In September 2020, all of the company’s production capabilities were relocated to a new facility 0.5 miles from the original office suite. Interestingly, this substantial expansion has been on the company’s radar for many years.

In 2002, a new management team was established. One of the goals the team set during its first few months was to find a permanent location for Horn USA. Large buildings in the light industrial zone are not commonplace in the immediate area of Horn USA, so it took a while to find the ideal opportunity.

Finally, in 2016, 10.76 acres with a 101,000-square-foot light industrial building became available. In typical Horn fashion, advantages and disadvantages were analyzed and finally one came together to the conclusion that this real estate among other things because of its proximity to the existing plant, provided the ideal solution to the next stage of expansion.

In the third quarter of 2019, construction began to bring the facility to the standards expected of Horn. In total, this meant an investment volume in buildings, conversion and technical equipment of approx. 29,000,000 dollar (approx. 25,000,000 euro). Nearly 400 people in all have been involved in the 14-month construction project. The new building has a total area of 11,000 square meters and can accommodate up to 300 people. Horn USA currently employs 120 people.

According to Andreas Vollmer, President Horn USA,

“The new building in the USA makes a clear statement and demonstrates our commitment to the American market. Other than our home market of Germany, this is our strongest international market and has been for a long time. It is also one that holds huge potential for our solutions in the future. The new building provides us with the space we are going to need for this. We are very proud of taking this step and are convinced that it will ultimately benefit our customers as well — in the form of increased production capacity, larger training rooms and our new demonstration centre, for example.”

Horn USA is very excited about their future home!
They would love if you stopped back here to check in on their progress!

At IMTS 2018, HORN USA presented two new developments in the area of whirling processes.

The JET Whirling System is the first whirling tool to feature an internal coolant supply. This whirling system offers optimized cooling directly at the cutting edge and was developed by HORN USA in conjunction with W&F Werkzeugtechnik.

Another innovation is the High-Speed Whirling Technology, which delivers high levels of productivity. In this process, the speeds have been specially adapted so that preturning and thread whirling can be carried out in parallel using a single work operation.

Through the JET Whirling process, HORN USA is demonstrating its expertise in the area of thread whirling. As part of a collaboration with W&F Werkzeugtechnik in Großbettlingen, experts from both companies have jointly developed a whirling system with an internal coolant supply.

By cooling the cutting edges directly, this system enables long tool life to be achieved. What’s more, when used in conjunction with the stable whirling unit, the system achieves better surface quality on the workpiece. Thanks to the patented W&F interface with its coordinated contact system for the tapered and planar surfaces, the whirling head boasts a high changeover accuracy and is easy to change with just three screws. The internal coolant supply reduces the risk of chip build-up between the cutting inserts.

It takes less than a minute to change the whirling head on the whirling unit interface. This interface offers a radial and axial run-out of 0.003 mm. The maximum speed is 8,000 rpm. The whirling heads are available with type S302 triple-edged indexable inserts or with type 271 double-edged inserts. The cutting edges are available with diameters of 6 mm, 9 mm and 12 mm. The interfaces for adapting the whirling unit are available for all standard Swiss-type lathes.
