BLUM Workpiece Touch Probes

Touch probe systems by BLUM can be used for the most varied measurement and monitoring tasks in machine tools.

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.

Contour Measurement

The touch probes can be used for contour measurements using the FormControl measurement software.

Additional information

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.

Single & Mass Production

Ideally suited to mass production under the harshest conditions thanks to its rugged design and protection class IP68.

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.

Receiver Systems
BLUM Receiver RC66

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

Quickstart measuring cycle packages
BLUM Quickstart measuring cycle package for touch probes

Quickstart measuring cycles for BLUM workpiece touch probes are user-friendly subroutines of the machine control. They can be used for workpiece referencing as well as for measuring during the production process.

The following measuring cycle packages are available for the TC50 | TC60 touch probes:

  • Quickstart
  • Quickstart Basic
  • Quickstart T
  • 3D Vector Probing
FormControl measurement software
BLUM CNC touch probe on freeform surface

User-friendly software for rapid quality control of contour measurement and standard geometric elements in CNC machining centres. You create the measuring programme for complex measuring tasks easily on the PC and transfer it to the milling machine.

FormControl V4 measurement software – Measuring at the click of a mouse in CNC milling machines


The touch probe systems are ideally suitable for fast and highly accurate measurement on machine tools used in single and mass production.
