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.

Pulling Measurement

Fast measurement of inside widths, outside widths and recesses using pulling/pushing measurements in Z+/Z-.

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.
