BLUM 3D CNC Touch Probes

3D CNC 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- with the help of cranked styli.

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.

Torsion Measurements

Unlike conventional touch probes, the unique shark360 measuring mechanism also allows for measurements in which a torsional force acts on the measuring mechanism.

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.
