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 regarding cutting edge breakage and missing tool inserts.

Tool Form Measurement

Setting and monitoring of length, radius and cutting edge radius on tools with circular cutting edge geometry.

Tool Form Monitoring

Monitoring for cracks or wear by scanning the tool 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-dependant thermal behaviour of machining centres.


Rapid run-out monitoring in less than 1 second for highly productive machining centres.

* The technology cycle is available for selected controls.


Fast monitoring of tool cutting edges for microbursts in a highly productive environment.

* The technology cycle is available for selected controls.

3D RadiusControl*

Recording of form error on tools with circular cutting edge geometry. Data basis for 3D tool radius compensation “3D-ToolComp” by Heidenhain.

* The technology cycle is available for selected controls.


Length, radius and angle measurement on tools with angular edges such as spot facers, engraving mills, etc.

* The technology cycle is available for selected controls.


Monitoring of conical cutting tools such as conical thread mills/formers, chamfer cutters, end mills, etc.

Reliable tool cleaning by BLUM blow nozzles
Blow nozzle for tool cleaning
  • 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
Blum-Novotest 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

Success Stories

The BLUM laser measuring system is installed in the middle of the work area, perfectly protected against coolant and chips
In addition to the precision, we were particularly impressed with the level of reliability. The system developed by BLUM exceeds our expectations in every respect.
