P 26 – For a wide range of applications covering all aspects of gear and geometry measurement
Compact and designed to meet the needs of the automotive industry, the P 26 Precision Measuring Center is extremely popular with customers. Its success story spans several decades and was built on a foundation of new measurement and evaluation methods, the implementation of innovative measuring systems, and uniform quality and reliability. After more than 30 years, Klingelnberg is breaking new ground in machine control technology. The seventh generation of machines is equipped with the latest Beckhoff controller, which is compatible with all current and future add-ons and designed to meet the requirements of the new EU Machinery Directive, now and in the future. It is because of their accuracy and reliability that Klingelnberg Precision Measuring Centers are used as a reference around the world, not just by countless customers, but also by renowned metrology institutes. With the latest advancements, the established combination of tactile (3D NANOSCAN) and optical measurement technology (HISPEED OPTOSCAN) for measuring cylindrical gears is now also available for this model series. In addition to optical pitch measurement, continuous helical measurement is performed across the entire perimeter and face width. This allows both the profiles and the topography of all teeth to be measured. The considerable time advantage over tactile measurement, along with the new possibilities this creates for practical applications, takes deviation analysis for noise detection to a new level.

P 40 – Universal all-rounder for reducing measurement times in series measurement using a hybrid solution
The hybrid measurement technology introduced in 2020 was developed to meet the demand for higher measurement speeds without compromising accuracy. The goal is to inspect as many components as possible using the fewest machines possible. Hybrid measurement technology is continuously being refined to expand its range of functions and create additional value, with a focus on meeting customer needs. All Klingelnberg Precision Measuring Centers in the 6th and 7th generation P 26 to P 65 series can be optionally retrofitted with the optical sensor (HISPEED OPTOSCAN). This technology is available as an optional feature for current precision measuring centers, along with the aforementioned measuring and evaluation options. Through the systematic use of the standardized Gear Data Exchange (GDE) interface when importing and exporting data and measurement results, Klingelnberg has set a higher standard in metrology 4.0 in the area of measurement results diagnostics and networking of production machines and metrology – a system it calls the Closed Loop.

R 300 – The Gear Noise Finder
The measurement technology in the R 300 Höfler Cylindrical Gear Roll Testing Machine can reliably determine the root causes of gear noise resulting from poor gear quality. Due to the short measuring time, the R 300 can be easily integrated into any manufacturing process and enables 100 % quality control of the gears produced. The R 300 is designed for all roll testing processes that are relevant for evaluating the running behavior and noise behavior of gears. These include the single flank test, the structure-borne noise test, and the torsional acceleration test. The double flank test can also be performed if needed. 

Depending on its equipment, the R 300 enables testing of gears and shafts, a particularly important factor for components in an electric vehicle drivetrain system (eDrive). Due to 100% quality control, a considerable amount of data is generated compared to random sampling. For data analysis and reporting, the data from the R 300 can be processed appropriately using the Klingelnberg Gear Noise Analyzer (GNA) software and tolerances developed for production monitoring.

Speed Viper 300 – for high-volume generating grinding in large-scale production
Designed for high-volume generating grinding and polish grinding in large-scale production, the Höfler Speed Viper Cylindrical Gear Grinding Machine is available in three different machine models to suit individual requirements: Speed Viper 300 in a single-spindle configuration, and Speed Viper² 180 and 80 in a dual-spindle configuration. The Speed Viper is designed for maximum workpiece diameters of 80, 180, and 300 mm, depending on the model. The Speed Viper² dual-spindle concept ensures minimal non-productive time. With a partial or full automation system, the Speed Viper can also be equipped with an automation interface that meets the VDMA 34180 standard. The Gear Operator machine software and a process-oriented navigation system via wizard technology make operation easy, even in the most complex applications. Last but not least, modern drive and control technology guarantees maximum energy efficiency.

G 30 – Quiet Bevel Grinding for noise optimization of ground bevel gears
Quiet Bevel Grinding is Klingelnberg’s solution for optimizing the noise characteristics of ground bevel gears. It involves applying a low-frequency harmonic variation in machine kinematics from tooth space to tooth space to individually modify the topographies of each tooth flank. As a result, individual tonal frequencies are excited and sound energy is distributed across other frequencies. The resulting sound resembles a multi-frequency noise similar to that of lapped gear sets, which is perceived as significantly more pleasant to the human ear. In production, the appealing feature of Quiet Bevel Grinding is that it can be implemented without affecting cycle times and does not interfere with gear measurement. Thanks to the targeted distribution of modifications around the component’s perimeter, the tried-and-tested Closed Loop can easily be used.

ROTEC measuring systems – precise rotational speed and angle measurement
Klingelnberg’s subsidiary Rotec will present its solutions for high-precision measurement and evaluation of rotational speeds and angular positions. The angle-based measurement approach and data processing in the order range are particularly suitable for analyzing rotating components, identifying transmission errors in gear units, conducting single flank tests, and analyzing drivetrains. To perform these tasks, the Rotec measuring system includes speed sensors, signal conditioning, the modular RASdelta measuring system, and the measurement and analysis software. Additionally, the Rotec Engineering Team provides external services for comprehensive measurement projects. 

Smart Factory – the future of the manufacturing industry
Smart Factory is revolutionizing how products are designed, built, and delivered. Through the integration of IoT, AI, and real-time data analytics, factories are becoming more intelligent, efficient, and adaptive than ever before. From predictive maintenance that minimizes downtime to digital workflows that streamline operations, Smart Factory unlocks higher productivity, reduced costs, and improved quality. The future of the industry isn’t just automated—it’s connected, data-driven, and optimized for peak performance. Our team of experts will be presenting this new solution at the EMO trade fair in Hannover. 

Advanced tooling systems – solutions for every challenge
