3D datasets of insert and injection valve


Measure flanks with more than 90°

Optical CMM enables lateral probing

So far, geometries such as the bore holes of e.g. injection valves in the automotive industry could hardly be measured optically. Lateral probing of components with vertical surfaces was limited to tactile measuring systems, CT solutions or complex special solutions. This changes with a new function of the optical coordinate measuring system µCMM. Vertical surfaces of more than 90° can now also be measured optically.

Optical hole measurement

Vertical surfaces of more than 90° can now also be measured optically. The diameter-depth ratio of holes ranges from 1:3 to 1:10, the measurable diameter is 0.1 mm to 2 mm. Users measure parameters such as outside and inside diameter and opening angle.

More measurable parameters

Reference surfaces, contours, lengths etc.

In addition to holes, dimensional features such as reference surfaces, contours, lengths etc. can thus be optically measured with high accuracy, in high resolution and in short measurement times.

Multiple hole measurement

with automatic rotation unit "µCMM Real3D”

In combination with an automatic rotation unit "µCMM Real3D", turning the 3-axis CMM into a 5-axis system, multiple holes including their orientation to each other can be measured. One application which can be achieved using the µCMM in combination with Real3D is the measurement of injection nozzles including diameter, K-factor, injection angle and side angle.

Vertical Focus Probing

Extension of Focus-Variation technology

The patent pending method for hole measurement "Vertical Focus Probing" is an extension of the Focus-Variation technology and is based on the use of a partial light cone. Individual diffusely reflected light rays from vertical surfaces are captured by the lens. Flanks with more than 90° are traceably measured in high-resolution and high repeatability. Vertical flanks measured in this way can be used, for example, to fit a workpiece coordinate system.
