DIGILOG touch probes for CNC machine tools

DIGILOG touch probes by BLUM are used for fast and automatic inspection of workpiece contours during mass production. Specially designed for the harsh conditions in machine tools, the analog measuring systems are an effective solution for improving the accuracy of your workpieces and the productivity of your manufacturing lines.

Scanning probes are similar to standard touch probes because they verify shape dimensions, but they use a different process. Instead of recording values based on various touches to the part, scanning probes actually scan the part, recording a constant stream of data. Next, a comparative measurement between a master part and the workpiece is created. The system then provides pass or fail feedback directly onto the machine's control.

Mounted directly into the machine's spindle, scanning probes communicate wirelessly via radio with the machine tool's control. The CNC program can be modified to scan various workpieces within the same machine tool providing:

  • Contour scan

  • Shape profile

  • Detection of part discontinuity


BLUM offers a steadily expanding selection of DIGILOG touch probe systems for machine tools. The measuring systems combine the functionality of a digital touch probe and an analog touch probe in a single device.

Ensure you produce the right part the first time.

In-process measurement has become an integral element of CNC machining because it helps ensure you produce the right part the first time. This is because the process allows parts to remain inside the CNC without disrupting the machine setup while inspection is being conducted. The measurement device is connected directly to the machine control, therefore data feedback can be analyzed and then displayed via the machine's interface. Rework is possible by compensation of the tool wear or workpiece origin based on the measurement analysis. 


Focus on productivity.

Utilizing in-process measurement can help to increase productivity by improving part accuracy the fist time and reducing scrap from rejects, all with minimal or no operator intervention. In addition, in-process measurement collects important data that can be used to provide insight to better understand and improve the manufacturing process.
