Since 1969, Paul Horn GmbH in Tübingen, Germany has been manufacturing high-precision cutting Tools.
The company, which currently employes 1400, develops and manufactures carbide grooving tools. The Paul Horn GmbH has branches and representatives in more than 70 countries around the globe. Our main customers are companies in the automotive and aeronautical sectors, engineering, chemical, medical and other industries. Our core expertise comprises research and development, in-house coating technology, in-house carbide production and in-house development of manufacturing technology.
The core Business of the Paul Horn Gmbh are carbide grooving tools. A wide range pf grooving, parting off, face grooving, thrading and broaching tools are availabel for application on CNC lathes. For MC groove milling tools for circular interpolation, bore milling, thread milling and reaming tools are available.
Besides the wide range of standard tools available off the shelf, the Paul Horn GmbH offers also customized tools, manufactured according to cutomers requirements.
Process Horn turbo whirling® – pre-whirling and finish-whirling in one single process
The newly developed Horn turbo whirling process optimises machining during thread whirling and increases cost-effectiveness. Horn has developed a set of cutting tools for whirling that feature a new cutting division concept. These are specifically designed for machining threads with a larger allowance. To this end, individual cutting edges work as pre-cutters and machine the workpiece to the defined external diameter. In the case of nine-insert tool, the cutting division concept allows the machining work to be divided up so that each cutting edge is subject to equal load, meaning that individual cutting edges can achieve significantly longer service lives. The finishing cutting edges produce the finished thread flanks within the optimised working range. Regardless of the external workpiece diameter, combining a range of cutting edge profiles creates an optimum thread with reproducible tool lives.
Horn turbo whirling can be used to produce single-start and multi-start threads and profiles. What's more, the S271 precision-ground double-edged indexable inserts are tailored to the respective thread profile and the material to be machined. The indexable inserts are clamped in positive-fit, highly stable insert seats, either in the new modular whirling heads with optimised handling during insert replacement or conventionally in the Mono block tools.
Horn titanium milling cutters: An extensive range of tools
Horn has developed an impressive array of special tools for machining titanium materials such as Ti6Al4V. With their sharp cutting edges, positive cutting angle, large relief angle and polished cutting edges, these tools are designed to overcome the main problems encountered during titanium machining. The TSTK cutting material grade that Horn has developed for its solid carbide milling cutters is specifically intended for machining titanium in the aviation/aerospace and medical technology industries. As well as offering good tribological properties and high temperature resistance, this introduces minimal heat into the substrate and acts as a kind of thermal shield. Another important aspect that had to be considered when developing the solid carbide end mills was that they had to have different helix angles and different pitches. This ensures a soft and gentle cut while avoiding vibrations. Sufficient quantities of coolant are essential when machining titanium. The Horn titanium range includes a completely new line of solid carbide milling cutters with diameters ranging from 2 mm (0.0787") to 20 mm (0.7874"). These are available with four or five cutting edges and in 2 x D and 3 x D versions.
New six-tooth cutter with brand-new high-performance coating
The 64T six-edged grooving insert is the latest addition to the Horn grooving range. The type 64T insert is precision sintered and is currently available with a grooving width of up to 3.29 mm (0.1295") in the .00. geometric shape. As a neutral grooving insert, it can be used on either the left or the right in square shank holders with internal cooling. The holders measure 16 mm x 16 mm (0.6299" x 0.6299"), 20 mm x 20 mm (0.7874" x 0.7874") or 25 mm x 25 mm (0.9843" x 0.9843"). An adequately dimensioned clamping screw holds the grooving insert precisely, keeping it central in the insert seat and ensuring a high level of process reliability. The type 64T insert supports grooving depths of up to 3.5 mm (0.1378") and a maximum workpiece diameter of 65 mm (2.5591). The new EG55 high-performance coating grade considerably improves the tool life and makes the grooving insert the perfect all-rounder for machining all types of steel as well as a wide range of other materials.
