Precision that creates new possibilities. Where the technical literature ends, our strength begins: with a deep understanding of the process, tailor-made procedures and optimized cutting tools, we make even the most complex honing tasks ready for series production – efficiently, economically and reliably. After all, new honing or special machining processes are not a product of chance, but the result of perfect coordination: from pre-machining, cutting material, workpiece material and process reliability – everything is precisely designed to work together.
Our proven honing technology combines precise lifting and turning movements with intelligently applied cutting tools to achieve maximum dimensional accuracy, precise shape accuracy and stable surfaces – even with challenging geometries such as blind holes, cross holes or grooves. Your benefit: tailor-made series solutions that make your production more powerful, future-proof and measurably more efficient.
When it comes to honing high-precision cylinder molds in large and small series, we have been the most sought-after and globally successful partner in engine production for decades.
Precision that makes engines better. In engine production, every detail counts – and every bore. As a leading global partner, Nagel has been perfecting high-precision cylinder shapes for decades. With contour honing, we go one step further: we specifically create individual geometries that guarantee maximum cylinder rigidity even when assembled and at operating temperature. Your benefit: less friction, lower noise and oil consumption – and engine performance that sets noticeably new standards.
We have already proven in series production for various customers that we can do this with the required responsibility, precision and suitability for series production.
Innovation that sets new standards. Contour honing is more than just a process – it is a technological milestone. Nagel has already proven in numerous series productions how complex requirements can be mastered with the highest precision, responsibility and suitability for series production. Our tools are as flexible as your applications – for modern engine concepts in all variants. Tool concept – flexibility for every engine production:
Our exceptional flexibility in track design and intuitive operation were recognized with the Red Dot “Best of the Best” award. Thanks to the systematic tool design, individual adaptations are possible at any time – even for future requirements. The patented tool design also allows: the creation of piston speed-dependent surface structures (strip honing), precise honing with minimal honing overflow and stable series use worldwide.
Your advantage: maximum flexibility, maximum process reliability and series solutions that make your engine production noticeably more efficient and future-proof.
The next evolutionary step for aluminum raceways. With the innovative spiral gliding honing process, Nagel takes the precision machining of aluminium cylinders to a new level: The process creates a uniform, functionally optimized surface over the entire cylinder area – and thus creates constant tribological conditions from the first to the last minute of operation.
The effects: noticeably reduced friction, significantly lower oil consumption over the entire service life and a significant minimization of gusset wear. The result: maximum efficiency and a demonstrably longer service life – proven by long-term tests with over 3000 hours of operating time.
High-speed honing combined with a shortened process chain for fine boring
Your benefit: significant savings in investment and operating costs
Cost-effectiveness redefined. With BOREHONE, the process jointly developed by Nagel and GROB, modern high-speed honing replaces classic finish fine boring – including integrated diameter measurement. This not only reduces the number of machines and investment volume, but also energy consumption, tool costs and personnel costs.
Your benefit: maximum savings without compromises – because the tried-and-tested division of tasks between fine boring and honing is retained. The result: maximum process reliability, perfect surface quality and production that is ready for the challenges of tomorrow. BOREHONE – when innovation becomes an efficiency revolution.
Precision at the highest level. When shape and dimensional accuracy of less than 0.001 mm is required, the strength of Nagel’s Precidorhon technology comes into play. With an adjustable mandrel, tailor-made cutting surface and user-friendly operation, we ensure reproducible top results – even with complex geometries.
The entire machining of a honing operation takes place in one stroke (in special cases, several strokes are also possible). The tool is permanently set to the machining diameter, making the process particularly user-friendly. Wear compensation takes place automatically if required. Whether drilling with or without interruption, the fixed presetting to the machining diameter, the automatic wear compensation and the multi-stage process control enable maximum precision, perfect surfaces and maximum efficiency – even under the most demanding conditions.

Precidorhoning can be combined with a conventional pre-honing operation or as a multi-stage precidorhoning process. This is particularly advantageous for large allowances and the highest precision requirements.
