BLUM Workpiece Touch Probes

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.

ContourScan

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 measuring system’s modular design allows for customer-specific adaptation to special measurement 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 the machining steps.

Coolant load

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

Mass Production

Perfectly suitable for 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-dependent thermal behaviour of machining centres.
