Tools that boost your productivity

For years, EMO Hannover has served as a benchmark for the machining industry. At Paul Horn's booth, as usual, it rained innovations that guarantee shorter machining times, better surface quality and high accuracies. We list the most important ones for you.

Paul Horn GmbH presented a new variant of its successful precision tool system at EMO. The new geometry HP is suitable for drilling, turning out, surface turning and over-turning. Horn thus offers a multifunctional tool for multiple applications. With the new blade geometry, higher cutting values and feed movements are possible. When turning out, a flat 90° shoulder is created at the base. The drag cut (Wiper geometry) ensures high surface quality even at high displacements. The system is also suitable for full drilling with a diameter of 3 mm to 7 mm. The Supermini HP offers the option of immediately turning out the inside contour after drilling - without a tool change. The single-cut design also allows different bore diameters to be produced with one tool. In addition to the new geometries, Horn developed a new holder system for the Supermini Typ 105. The new tension no longer uses the casing surface, but a tension wedge at the front. This leads to a higher holding force of the cutting plate and thus high rigidity of the entire system. The new tension also increases the repeat precision when changing the cutting plate and ensures better utilization of the available construction space by front operation. This is a great advantage on long-turning machines, since the user can change the cutting insert without having to dismantle the toolholder.

High performance in stainless steels and superalloys.

High quality stitching process with high cutting values

Paul Horn offers new holder variants for the S100 boning system for boning on turning/milling machines with displacement via the Y axis. This enables a high-quality cutting process with high cutting values and thus shorter machining times. In addition, there is the option of trimming large diameters with a compact cutting holder and trimming with narrower cutting widths. Due to the new positioning of the knife in the tool carrier, the cutting forces are directed into the main cross section of the pitch holder. This results in a higher rigidity of the entire system at the same cross-sectional area of the pitch holders. This enables greater displacements at the same stitch width. Thanks to the friction force connection in the longitudinal direction of the tool, narrower holders can be used at the same rigidity of the system. In modern generations of turning and milling machines, cutting off with the new pitch tools results in the cutting force being applied in the spindle direction, increasing the rigidity of the overall system.

High heat resistance for new coating IG35

With the new tool coating IG35, Horn tool systems offer high performance and tool life when machining stainless steel, titanium and superalloys. In combination with geometries 3V and FY, the aluminum-titanium-silicon nitride coating inhibits the formation of build-up edges thanks to its low friction values. Due to HiPIMS coating technology, the coating is very smooth with high heat resistance. In addition, the tool coating is free of layer defects such as droplets or other flaws at the cutting edge. Horn tailors the coating system, clamping geometries and micro geometries to typical applications such as internal and external piercing, long-turning, circular and solid carbide milling. The user can select higher cutting values, which can reduce cycle time, which also has a positive effect on piece costs. In addition, the use of the new coating increases surface quality. The IG35 coating is available for the pitch systems S100, S101, S224, S229, S274 as well as for the circle milling system and the solid carbide milling system.  

Six cutting edges ensure economical price

High accuracies and surface quality

Paul Horn GmbH is consistently developing the M610 tangential milling system further. After the disc cutter, the program is now being expanded to include a 90° angle cutter and new cutting materials. The patented tool system ensures a soft cut with positive clamping and axial angles. The precisely ground inserts offer six usable cutting edges for high accuracies and surface quality. The additional free plane phase ensures a stable wedge angle and a particularly quiet milling process. The milling body is protected from abrasive chips with a special surface treatment. With six cutting edges per insert, this is an economical option. For machining different materials, HORN offers the cuttingplates in AS46, IG35 and NE2B substrates in right and left versions and with corner radii of 0.4 mm or 0.8 mm. The maximum depth of cut (ap) is 9.9 mm.

Roller stitching of large modules

Roller cutting of larger modules requires large and rigid milling/turning machines that allow the required synchronization between workpiece and tool spindle. Following the experience with small solid carbide roll pitchtools HORN puts the collected knowhow now in for larger modules. The tool system is based on cutting platetype S117. The patented plate seat of the single-cut tool ensures accurate tension and positioning at high rigidity of the overall system with high repeat accuracy. The ground chip guide level and direct screw connection of the cutting plates ensure very good chip removal from the machining zone. All blades are directly cooled by the internal coolant supply. Horn's product range consists of a wide tool program for the production of different toothing geometries from module 0.5 to module 30.
