Blum-Novotest, a leading provider of innovative and high-quality measurement and testing technology, presents the new LC54-DIGILOG at EMO 2025 in Hannover, the most compact laser measurement system in the LaserControl-DIGILOG series to date. Specifically developed for tool measurement and monitoring in micro machining, the system sets new standards in precision, compactness, and process reliability.
Winfried Weiland, Head of Marketing at Blum-Novotest, explains: 'The demands for precision in micro machining are continuously increasing – especially when measuring extremely small tools. With the new LC54-DIGILOG, we have developed a system that not only meets these challenges but also defines new standards. It offers the full functionality of the established DIGILOG laser measurement systems for tools in the range of 10 µm to 16 mm in diameter.'
It was designed from the ground up for use in highly compact machine concepts and impresses with a variety of technical innovations that make it the most powerful and precise laser measurement system in its class.
As the direct successor to the long-proven LaserControl Nano NT, the LC54-DIGILOG builds on its strengths and surpasses it in nearly all areas. The heart of the new system is the DIGILOG technology, first introduced in 2017. While classic digital/switching laser measurement systems generate only a few signals by shading the tool, the LC54-DIGILOG generates several thousand measurement values per second – with dynamic adjustment of the measurement speed to the nominal speed of the tool. Each cutting edge is measured individually, allowing for a precise comparison between the shortest and longest cutting edges. This achieves a repeat accuracy of 0.2 µm (2σ), and run-out errors, such as those caused by contamination at the tool holder, are automatically detected. Additionally, the system identifies dirt or coolant residues on the tool and subtracts them from the measurement result.
The multitude of innovations integrated into the LC54-DIGILOG by BLUM developers brings tangible benefits to users: Measurement and testing times have been reduced by up to 60 percent. At the same time, the laser optics of the system have been perfected for the requirements of micro tools. An optimized beam shape and a focus diameter reduced by 30 percent enable an absolute accuracy that surpasses all previous systems – even those with blue laser light. A special innovation is the MicroTool mode:
For small tools, this is automatically activated and allows for significantly increased measurement accuracy – a crucial advancement for the precise measurement of delicate tools.
A central element of the LaserControl DIGILOG series is the seamless integration into the powerful measurement and visualization software LC-VISION. This has been specifically developed for BLUM's DIGILOG systems and offers an intuitive user interface for configuring, visualizing, and evaluating measurement processes. The new GrindingControl function available for LC-VISION will celebrate its premiere at EMO: It allows for the precise determination of the actual geometry of grinding tools. Using intelligent algorithms, the software determines an optimized processing dimension from the captured measurement data and automatically transfers this to the tool table. Alternatively, standard measurement processes can be conveniently generated and integrated into the processing program through integration with common CAD/CAM systems such as those from Mastercam.
'Another highlight of our EMO exhibition is the cooperation with the clamping technology manufacturer SCHUNK,' explains Winfried Weiland. 'Its battery-operated clamping devices will soon be compatible with our BRC radio technology, enabling wireless, automated communication between clamping technology and machine. Particularly advantageous for customers: If BLUM measurement systems with BRC radio technology are already installed in the machine, the new SCHUNK clamping devices can be integrated and operated particularly easily and cost-effectively – saving time, reducing installation effort, and increasing flexibility in production.'
