BLUM tool measuring probes for tool setting and tool breakage detection

3D tool measuring probes by BLUM can be used for the most varied measurement and monitoring tasks in CNC machining centres.

Tool Breakage Detection

Breakage detection of centric tools such as drills, mills, engraving tools, taps and reamers.

Tool Length Measurement

Automatic setting and wear monitoring of tools by quick and precise length measurement.

Tool Radius Measurement

Automatic recording of tool diameter and wear by quick and precise radius measurement.

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.

Coolant load

Reliable and fast measurements in coolant thanks to modern measuring mechanism and robust design.

Mass Production

Perfectly suitable for mass production under the harshest conditions.

* Depending on geometry and material of tool. Probing force must not result in damage to tool.

Additional information can be found in the relevant brochure and in the operating manual.

Receiver systems

For wireless data transmission between BLUM measuring systems and the machine tool, compact receiver systems incorporating the latest transmission technologies are used.

BLUM Measuring Cycles

The measuring cycles are user-friendly subroutines of the machine control. They can be used on milling machines for the following measuring tasks.

  • Calibrating the probe
  • Tool length measurement
  • Tool Radius Measurement
  • Tool wear monitoring
  • Tool breakage detection

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.

Blow nozzles for tool cleaning

The optional blow nozzles by BLUM effectively clean the tool and measuring surface of any coolant and chips.


In addition to simple tool breakage detection, the tool setting probes are also used for tool setting in length and radius.
