Dimensional accuracy & surface finish measurement

NEW: InfiniteFocusG6

    InfiniteFocusG6 is an accurate, fast and universal optical 3D measuring instrument for tolerances in the µm and sub-µm range. Components are measured area-based and with high resolution independent of size, material, geometry, weight and surface finish. A number of proven and new features combine the functionalities of a roughness measuring system (Ra, Rq, Rz/Sa, Sq, Sz) with the characteristics of a coordinate measuring machine. 

    InfiniteFocus is ideal for manufacturing. The robust Focus-Variation technology and the vibration-insensitive design ensure high-resolution and repeatable results, even directly next to the machine tool.

    The brand new InfiniteFocusG6 stands for:

    10 questions about the InfiniteFocus G6

    In the following article we have summarized the most important features of InfiniteFocus G6 for you. Get answers to these and other questions:

    • Which technologies is the measuring system based on?
    • How fast is the new InfiniteFocus G6?
    • For which surfaces is InfiniteFocus G6 suitable?

    A number of proven and new features combine the functionalities of a 

    roughness measuring system with the characteristics of a coordinate measuring machine:

    Icon MetMaX

    The expansion from 3 to 5 axes allows measurements of geometries that are otherwise difficult or impossible to access. High-precision tilting and rotating axes enable the measurement of GD&T and roughness parameters on the entire measured object.

    Icon Real3D

    SmartFlash & Real3D:
    The integrated SmartFlash technology ensures high-resolution measurement of smooth, reflective and highly polished surfaces. Real3D turns individual measurements into a complete 360° data set.

    Icon 5-axes technology

    MetMaX user software
    Users specify measurements already in the CAD model of a component. A Digital Twin combined with a virtual measurement simulation enable safe operation of the measuring instrument.

    Icon Vertical Focus Probing

    Vertical Focus Probing:
    The latest technology enables the optical, lateral probing of components. Users measure holes and vertical flanks (>90°).

    Measurement examples with InfiniteFocusG6:

    Smooth surface

    Thanks to Advanced Focus-Variation, users measure workpieces with steep flanks, varying reflections and structured roughness. The integrated SmartFlash technology ensures high-resolution measurements of smooth, reflective and highly polished surfaces.

    Bone screw

    By applying Real3D technology, users achieve full form measurements of a component (360°). Here, a direct comparison to the respective CAD data set is shown. In addition, roughness can be measured.

    Pick & Place - Automated placing & measurement of components

    The measurement solution Pick & Place was presented at Advanced Engineering Show 2019 in the UK. Therefore the optical measurement system InfiniteFocus is extended with a collaborative robot to automatically pick, place, measure and sort (OK/ not OK) components in production. Watch the video and have a look at the automated measurement solution.

    Technology - Focus-Variation & Vertical Focus Probing

    Measurement of form and roughness with one system? Lateral probing of components with vertical surfaces up to 90? All this is possible with Bruker Alicona optical 3D metrology. Learn more about our core technologies from our R&D Director Franz Helmli and Sales Manager Urban Muraus.
