Laser Measuring Technology

LC50-DIGILOG, a newly developed laser measuring system.

DIGILOG technology generates thousands of measurements per second, increasing the speed, precision and in-process reliability of tool measurement in machining centers.

The new LC50-DIGILOG features optimized laser optics.

The compact BLUM smartDock is the standard interface for all new carrier systems. It is offered in three variants and includes, in addition to the electrical, mechanical and pneumatic connections, all necessary pneumatic valves.

"The new HPC nozzle with 25% greater cleaning pressure enables even more effective cleaning of the tool cutting edges," said a company spokesperson.

Blum-Novotest will present the redeveloped laser measuring system LC50-DIGILOG. The new system with DIGILOG technology generates 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, 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 toolholder, for example, are also automatically detected. The new LC50-DIGILOG also 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.

"The new ideas implemented in the LC50-DIGILOG have advantages for users," said a company spokesperson. "Firstly, measurement and testing times have been shortened by up to 60%. In addition, the optics in the system were further improved so that the new generation achieves absolute accuracy due to an optimized beam shape and a 30% smaller focus diameter. Blum developers also further improved the homogeneity of the laser beam, making further analog 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 optimized design enables the measurement of tools that are up to 30% bigger, depending on the version used."

The compact Blum smartDock 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.

"In addition to realizing short measurement times, optimized precision and in-process reliability, users will also profit in the future from new, ground-breaking applications. These include the 3-D ToolControl software, which enables continuous digilog-based contour measurement of tools-including the visualization on the control screen, and the new SpindleControl technology cycle, which can be used to record and evaluate the state of a spindle bearing," said the spokesperson.
