Probes systems Trinity and Trinityᵐ
Machine qualification

Wireless probe comparison

Our Trinity and Trinityᵐ wireless probe systems are high-precision non-contact measuring systems, designed for fully automated machine performance verification. Both systems feature tool-changeable probes that operate automatically within your process. Compare the two to discover which best fits your specific requirements.

High-precision machine qualification



03.RA-on-6-axis-machine-toolMaintaining geometric accuracy in machine tools is critical to ensuring consistent part quality, reducing scrap rates and minimizing downtime. In multi-axis machining environments, even small deviations in linear or rotary movements can have significant impact on the production performance.

Our machine tool inspection and analyzer series offer a range of measurement systems to provide peace of mind by guaranteeing your machine is within specification. The Position and Rotary Inspector and Analyzer series employ IBS Precision Engineering’s patented wireless Trinity & Trinitym probe systems for linear and rotary axis measurement. Unlike other systems the Trinity probe systems’ unique design enables the execution of non-contact X, Y and Z measurements simultaneously with exceptional measurement speed and accuracy. The probe systems are designed for quick and accurate qualification of 3-, 4-, 5- and even 6-axis machines. 

Probe measurement

The probe is mounted in the spindle and a calibrated masterball or linear array is positioned on the machine table. As the spindle moves along a predefined path, the probe, representing the Tool Centre Point (TCP), measures its position relative to the masterball. This setup allows the system to capture positional errors in real time across multiple axes. 

With this data, the operator can immediately visualize deviations in the cutting path. Errors such as pivot line misalignment, squareness issues and linearity deviations become apparent, allowing corrective actions to be taken before they affect production.

In addition, both Trinity probe systems reveal problems like dynamic instability, incorrect controller settings or bearing degradation, issues that are often difficult to diagnose with conventional tools. The measurement uncertainty is less than 1 μm, providing the level of precision needed for demanding applications.

Trinity or Trinityᵐ probe?

Trinity and Trinityᵐ provide robust solutions for technical machine qualification tasks. Their wireless design, measurement precision and portability enable efficient integration into manufacturing environments where accuracy and uptime are critical. These tools serve as reliable components in predictive maintenance strategies, supporting both cost efficiency and production consistency.

Trinity

For larger machines or those requiring an extended measurement range, the Trinity probe variant may be the better choice. Trinity offers a range of 3.5 mm and Wi-Fi connectivity, making it more suitable for large-scale applications.

Trinityᵐ

Due to its reduced footprint, the Trinityᵐ probe is suitable for smaller machines where space is limited. It offers improved measurement accuracy (export controlled) and an extended battery life achieved through power-saving technology. For additional operational safety, an optional emergency stop (E-stop) feature is available.
