Technological excellence in the production of internal gears
We are a manufacturer of precision internal gears used in a wide variety of drive systems, couplings, and transmission components. We manufacture internal gears according to customer drawings, taking into account the required gear geometry, component function, and material selection.
Our company provides support ranging from production-oriented product design through CNC gear cutting to metrological quality assurance.
Using modern processes such as power skiving (roll skiving) and roll broaching (impact gear cutting) , we produce internal gears with precise dimensions and profiles, including involute gears for transmission components, as well as form-fit gears in accordance with DIN 5480 and , and notched gears in accordance with DIN 5481. The requirements for profile, pitch, and flank line are determined based on the component’s function and the agreed-upon quality specifications, taking into account relevant gear-cutting standards such as DIN 3962 .

Our services in internal gearing
- CNC-based manufacturing of internal gears with a module range of 0.3 to 8
- Power Skiving for high cost-effectiveness in internal and external profiles
- Butt gear cutting for deep or hard-to-reach geometries
- Hard finishing and gear grinding for maximum profile accuracy, flank quality, and surface finish
- Metrological inspection of every gear with documented quality in accordance with ISO 1328
- Prototype and series production on highly automated production lines
- Design & CAD support for customized gear-cutting processes
The selection of the internal gear cutting process depends on the module, number of teeth, gear length, material, and accessibility of the internal contour.
Innovative internal gearing through experience, technology and quality assurance
With decades of experience in precision gear cutting, we combine technical expertise, automated process control, and quality-assured manufacturing.
Our state-of-the-art CNC gear hobbing machines and power skiving systems enable short cycle times with consistently high tolerance accuracy.
We tailor the tool geometry, cutting parameters, and machining strategy to the specific tooth profile.
Inline measurement systems continuously monitor profile and flank quality to immediately correct dimensional deviations.
This results in internally gear-toothed components that ensure durable, backlash-free power transmission even under high torques.
The combination of CNC machining, documented measurement technology, and optimized process parameters ensures consistent component quality in series production.

Production portfolio and material expertise for internal gears
We manufacture our internal gears from a wide range of materials—selected to meet specific load, torque, temperature resistance, and corrosion requirements.
For heavily loaded gear components, for example, heat-treated steels such as 42CrMo4 are suitable. Aluminum alloys are ideal for weight-optimized designs, while stainless steel, nickel alloys, or engineering plastics are used depending on the operating conditions.
By using cutting parameters, tool geometries, and cooling strategies tailored to the material, we achieve consistent machining quality in the production of our internal gears. Depending on the material and machining process , surface roughnesses as low as Ra 0.8 µm can be achieved.

The achievable gear tooth quality and the appropriate manufacturing process depend on the specific material, its condition, and the geometric requirements.
Internal gears from automated high-tech production
Our production combines digital process control, predictive maintenance and closed-loop gearing technology, which enables continuously monitored and self-optimizing production. CAM-based programming (e.g. Inventor, Esprit) enables even complex tooth profiles to be manufactured efficiently, precisely and reproducibly.
Hydrostatic guides, multi-channel controls and temperature-compensated machine frames ensure micrometer-precise gearing quality.
From prototype to mass production.
