LC50-DIGILOG – A future-oriented laser measuring system

Laser measuring system for CNC machine tools that is unique worldwide for non-contact tool measurement and tool monitoring under the harshest conditions. Unbeatably fast, precise and reliable thanks to the latest DIGILOG technology, premium laser optics and perfected BLUM protection system.

Non-contact tool setting and tool monitoring

BLUM laser measuring systems have always been renowned for their high precision and in-process reliability. Thanks to the newly implemented DIGILOG technology, those attributes have been enhanced to a never before imagined level. Whereas the proven digital/switching laser measuring systems using NT technology only generate a small number of signals for recording measurements by shadowing the tool, the new DIGILOG laser measuring systems generate many thousands of measurement values per second while dynamically adjusting the measuring speed according to the nominal speed of the tool. The new laser measuring system LC50-DIGILOG also measures each cutting edge individually, rather than just determining the value for the longest cutting edge, meaning it is possible to make a comparison from the shortest to the longest cutting edge. As a result, run-out errors, caused by contamination on the taper of the tool holder for example, are also automatically detected. Furthermore, the new LC50-DIGILOG detects any contaminants and cooling lubricants adhering to the tool – due to the large number of measurements per cutting edge – and deducts them from the result to make measurement results even more reliable.


Convincing advantages for the user

The many new ideas implemented by the BLUM developers in the LC50-DIGILOG have resulted in impressive advantages for users: Firstly, measurement and testing times have been shortened by up to 60 percent. In addition, the optics in the system were further improved so that the new generation achieves an absolute accuracy that is better than all comparable measuring systems thanks to an optimised beam shape and a 30 percent smaller focus diameter. BLUM's developers have also further improved the homogeneity of the laser beam, making further analogue measurements possible. The influence of coolant mist has been further reduced enabling improvements in accuracy and in-process reliability. And despite its reduced external dimensions, the optimised design enables the measurement of tools that are up to 30 percent bigger, depending on the version used.

The compact BLUM smartDock represents another world-first. This innovative standard interface serves as the basis for all new support systems and contains all the necessary pneumatic valves in addition to the electrical, mechanical and pneumatic connections between the machine and laser measuring system. If the compressed air quality is in accordance with ISO 8573-1 class 1.3.1, the separate pneumatic unit required for the LaserControl NT can even be omitted completely.

With the LC50-DIGILOG laser measuring system, we have succeeded in raising a tried and proven technology to a new level. In addition to realising the shortest measurement times, optimised precision and in-process reliability, users will also profit in the future from new, ground-breaking applications. These include the 3D ToolControl software, which enables continuous digilog-based contour measurement of tools – including the visualisation on the control screen – which far exceeds the functions of significantly more expensive and complex image-processing systems. Or the new ‘SpindleControl’ technology cycle, which can be used to record and evaluate the state of a spindle bearing.
