Our measuring equipment portfolio at a glance

We use a laser interferometer to measure the geometrical deviations of a machine tool: Our measuring systems and optics help us to identify positioning deviations, straightness deviations, angular deviations of a linear axis and rectangularity of the movement axes.

The position-sensitive-device (PSD) can usefully be deployed in conjunction with a laser whenever there is straightness deviation in a linear axis. The advantages of this is the straightforwardness of use along with ease of installation, opening up the way for swift and robust measurement.

We deploy the »Laser Tracer« manufactured by Etalon AG to characterize machines with maximum precision. With its self-tracking function, the laser tracer follows the optical lens in order to reproduce three-dimensionally any changes in the distance from an object. Examples of its use include the complete calibration of 3-axis and 5-axis machine tools with different axis configurations and the acceptance and testing of coordinate measuring machines in accordance with ISO 10360.

The »Spindle Error Analyzer« is used to measure the accuracy of rotating spindles: The exact position of a sphere on the tool is measured by sensors working from different directions in very high frequency. The thermal properties of the rotating spindle can also be analyzed.

We deploy the »Ball-bar« to coordinate the path behavior of two motion axes: Geometric and dynamic deviations of the machines can be measured very swiftly via the circularity test, defective machine elements and adjustment faults can be identified and compensation and control parameters can be optimized. Used in conjunction with additional instruments, the ball-bar supports a range of analyses via the circularity test in three radii (50 mm, 150 mm and 300 mm).

We work closely with the Machine Tool Laboratory WZL RWTH University of Aachen to analyze dynamic machine behavior. This gives us access to additional measuring equipment and extensive know-how which enables us to provide an even more multi-faceted, dynamic characterization of machine tools.

The thermographic camera is used to measure the surface temperature of an object and to present it on an integrated display. The thermal behavior of the machine and associated processes can be analyzed on the basis of the measurement data.
