From EV transmission gears to bone screws and watch movements,
every industry brings its own materials, tolerances, and production challenges.
What they have in common is the need for tools that cut reliably from the first part
to the last. HORN combines a broad standard range with custom tool design,
and our local application engineers work directly
with your team to find the right solution for your part.
Automotive
Electrification and hybrid powertrains are reshaping automotive machining. New materials, new component designs, and high production volumes all demand tools that hold tight tolerances shift after shift. HORN works with OEMs and suppliers to adapt proven processes and develop new ones as the industry evolves.
At a glance:
Typical parts: transmission gears, shafts, housings
Materials: case-hardened steels, aluminum alloys, cast iron
Key processes: grooving, gear production, turning
Aerospace
Aerospace components keep getting lighter, stronger, and more efficient, and the materials that make that possible are some of the hardest to machine. Titanium, Inconel, and high-strength steels wear cutting edges quickly. Fiber-reinforced composites such as CFRP are highly abrasive and prone to fraying, delamination, and fiber breakage. HORN tools are engineered for these conditions, from carbide geometries for heat-resistant alloys to [PCD] tools for composites and metal matrix composites (MMC).
At a glance:
Typical parts: structural components, engine parts, fasteners
Materials: titanium, Inconel, high-strength steels, CFRP, MMC
Key processes: milling, drilling, turning
Medical industry
Implants, surgical instruments, and medical devices leave no margin for error. Parts are often small and complex, made from titanium, medical-grade plastics, or ceramics, and must be produced with complete process reliability. HORN designs tools for these applications from the ground up. The cutting material is matched to the workpiece, the geometry is optimized at both the macro and micro level, and the edge preparation is tuned to the cutting forces.
At a glance:
Typical parts: bone screws, implants, surgical instruments, device components
Materials: titanium, medical-grade plastics, ceramics
Key processes: thread whirling, small-bore machining, Swiss-type turning
Watches & Jewelry
In watchmaking and jewelry, a few microns decide whether a part fits and whether it looks right. Movements, cases, settings, and components are machined from stainless steel, titanium, gold, platinum, brass, and ceramics, often on Swiss-type lathes. Because the machined surface usually stays visible, the finish is part of the product. HORN supplies sharp inserts with polished rake faces and controlled chip formation in tight spaces, producing thousands of identical, burr-free parts. With precious metals, clean cuts and minimal rework also protect the value of the material.

Typical parts: movement components, cases, settings, jewelry components
Materials: stainless steel, titanium, gold, platinum, brass, ceramics
Key processes: Swiss-type turning, micro-grooving, small-bore machining
Tool & Mold Making
Injection molds, die-casting dies, stamping and forming tools, and electrodes are usually one-off parts. There's no trial run, so the tool has to cut correctly from the very first part, often during unattended shifts, under tight deadlines, and with long overhangs. That means machining hardened tool steels as reliably as copper, graphite, and aluminum, while producing deep cavities, fine contours, and surface finishes that reduce hand polishing. HORN tools are built for rigidity, low vibration, and predictable tool life. When the standard range reaches its limits, we'll develop a custom tool with you.
At a glance:
Typical parts: injection molds, die-casting dies, stamping and forming tools, electrodes
Materials: hardened tool steels, copper, graphite, aluminum
Key processes: milling, high-feed milling, drilling
Hydraulics & Pneumatics
Hydraulic and pneumatic components operate under high pressure and heavy loads, and they have to perform without fail. Sealing surfaces, press-fit connections, and the components that convert fluid power into motion all depend on tight tolerances and consistent quality. HORN offers a specialized range of precision tools for these features, including grooving tools for seal grooves and internal machining in valve bodies.
At a glance:
Typical parts: valve bodies, cylinders, pistons, fittings
Materials: steels, stainless steels, aluminum, brass
Key processes: internal grooving, reaming, thread cutting
