BLUM workpiece touch probe

Touch probes by BLUM can be used for the most varied measurement and monitoring tasks in CNC machining centres.

Position Measurement

Fast determination of current workpiece position (workpiece zero point) prior to machining or after resetting using digital (switching) measurement.

Measurement of Standard Features

Digital (switching) measurement of distances, single points, angles, inside and outside diameters, inside and outside widths on a manufactured workpiece.


Analogue scan of workpiece contours in machine tools with a resolution of 1000 measuring values per second. Deviations from the target contour are detected in the machining clamping process.

Modular System

The modular design of the measuring system enables customer-specific adaptation for special measuring tasks. BLUM offers a comprehensive range of accessories such as extensions and elbows for this purpose.

Workpiece Inspection

Inspection of the manufactured workpieces for machining errors and adherence to manufacturing tolerance by means of control measurements prior to clamping.

Adaptive Machining

Determination of parameters for adaptive machining and process control between and after machining steps.

Coolant Load

Reliable and fast measurements in coolant thanks to modern measuring mechanism with enhanced measuring force.

Mass Production

Ideally suited to mass production under the harshest conditions.

Wear Compensation

Tool wear is compensated for by taking measurements on the workpiece and comparing these with the nominal dimension.

Temperature Compensation

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

DIGILOG Software BCS 3.0
BLUM DIGILOG Technology evaluation screen
  • Evaluation and visualisation at the control screen or BLUM Touch Panel TP48-21
  • Early detection of “error trends”
  • Comparative measurement between master part and workpiece
  • Flexible definition of warning and tolerance limits per workpiece
  • Providing the tracked data in log files
Touch Panel TP48-21
BLUM touch panel TP48-21 for evaluation and visualisation of measurement results

Modern touch panel for retrofitting. It is used if visualisation and operation is not possible on the machine control.


The measuring systems with integrated DIGILOG technology by BLUM combine the advantages of a digital touch probe with those of an analogue scanning touch probe in a single device. Workpieces can be checked very quickly using the analogue touch probe for machining errors and contour deviations.
