BLUM standard measuring cycles

The measuring cycles for BLUM laser measuring systems can be used to measure and monitor over 90 % of all conventional cutting tools. The measuring cycles are available for many conventional controls. Your local BLUM-representative will gladly inform you about the range of features for your control.

Tool Breakage Detection

Non-contact breakage detection of centric tools such as drills, mills, engraving tools, taps and reamers.

Tool setting

Non-contact tool setting in length and radius at nominal speed including compensation of dynamic spindle drift at high rotational speeds.

Single cutting edge monitoring

Monitoring of tools for broken or missing cutting edges.

Wear compensation

Compensation of tool wear using measurements between the machining steps. The wear value is stored as an additive correction value in the tool offset memory.

Temperature compensation

Compensation of the temperature-dependent thermal behaviour of machining centres.

Single & mass production

Perfectly suitable for mass production under the harshest conditions thanks to robust design and protection class IP68.

LaserControl EC
  • Non-contact monitoring of sensitive tools
  • Optional single cutting edge monitoring
  • Available as single and mounting version
  • 100% in-process reliability due to Blum protection system
  • Top BLUM quality at an attractive price
Reliable tool cleaning by BLUM blow nozzles
  • Jet of air guided perfectly towards the measuring position
  • This provides residue-free cleaning of coolant, chips and pollution from the cutting tools
  • Integrated check valve: Prevents the accumulation of coolant in the feed nozzles and resulting contamination of the tool cutting edges.
Indispensable – the BLUM pneumatic unit
  • Guarantees low-maintenance operation
  • Enables low compressed air consumption
  • 3-stage filter system (5 / 0.01 / 0.001 µm activated charcoal filter)
  • Optimised valves with minimum switching times
  • “Puff effect” for best possible cleaning when opening the shutters
  • Outputs with finest filtered barrier air for linear displacement sensors and tool cleaning


The Micro Single NT laser measuring system is used in machine tools for non-contact tool measurement and tool breakage detection.
