Blum-Novotest, supplier of innovative and high-quality measuring and testing technology, recently launched its new laser measuring system. The LC50-DIGILOG has been completely redeveloped to revolutionize and future-proof the speed, precision and in-process reliability of tool measurement for CNC machine tools.
Alexander Blum, President of Blum-Novotest GmbH, says: “In-machine measurement has become established as an integral element of high-end CNC machining. Automated machines and virtually all five-axis machining centres are nowadays equipped with BLUM laser measuring systems. The prerequisite for this was the outstanding performance of systems under the harshest conditions as well as the associated possibilities in terms of automated tool measurement and monitoring. Based on that, it was by no means easy to upgrade the tried and proven laser measuring technology with NT technology. We achieved this innovative advancement by implementing the DIGILOG technology familiar from touch probes in the laser measuring system.“
BLUM laser measuring systems have always been renowned for their high precision and in-process reliability; with the implemented DIGILOG technology, those attributes have been further enhanced.
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 generates many thousands of measurement values per second while dynamically adjusting the measuring speed according to the nominal speed of the tool.
The LC50-DIGILOG also measures each cutting edge individually, rather than just determining the value for the longest cutting edge, making it possible to provide a comparison from the shortest to the longest tool cutting edge. As a result, run-out errors, caused by contamination on the taper of the tool holder are also automatically detected. In addition the 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 pricise.
Innovations embedded in the LC50-DIGILOG result in impressive user advantages including :
- Measurement and testing times have been shortened by up to 60 percent.
- Improved system optics with optimised beam shape and a 30 percent smaller focus diameter achieves best in class absolute accuracy.
- Coolant mist influence has been further reduced enabling improvements in accuracy and in-process reliability.
- Despite reduced external dimensions measurement of 30% larger tools is possible.
The compact BLUM smartDock represents a world-first. This innovative standard interface serves as the basis for all new support systems and contains all necessary pneumatic valves in addition to the electrical, mechanical and pneumatic connections between the machine and laser measuring system.
