High-End Model with Shape-Adaptive Speed Adjustment

The Leitz Infinity is a high-end CMM developed by Hexagon, based in Sweden. This model allows a combination of optical and tactile sensors in one unit and achieves efficient measurements through Variable High-Speed Scanning (VHSS).

Following the principle of "as fast as possible, as slow as necessary," the machine performs high-speed scanning for simple lines and automatically adjusts its speed when scanning complex areas. This ensures high-speed measurements while maintaining a high level of accuracy.

Closed-Frame Design for Stable Measurements

Snother distinctive feature of Leitz Infinity is its robust and stability-focused design. To ensure long-term stable measurements, it adopts a closed-frame design. The central moving measurement table does not twist or tilt.

The measuring section consists of a fixed portal with a cast iron base and a granite base-crossbeam. These strong design specifications form the basis for maintaining reliable measurements with high accuracy.

Continuous High-Speed Probe Head for Measurement of Deep Parts

One of the reasons facilitating the Leitz Infinity's high-speed measurement capabilities is its dynamic single point probing. The continuous high-speed-scanning probe head (LSP-S4) with a lateral extension probe of up to 800mm enables measurement of deep parts.

In addition, the integrated automatic weight balance system supports a stylus configuration up to a maximum of 1000g. This system corrects for probing deflection, allowing for more accurate shape and contour measurements.

Applications and Use Cases of the Leitz Infinity

Results on the same Level as the Federal Institute of Metrology

Gribi Messtechnik, a measurement services company in Switzerland, focuses on 3D measurement and 3D calibration services. Although already recognized as a certified calibration institution, the company aimed to further improve its precision.

While they also considered other machines, they ultimately chose the Leitz Infinity for its ability to deliver results in real-world scenarios, not just theoretical values. As a result, the company was able to provide measurement services boasting the highest accuracy domestically, with results being on part with those of the Federal Institute of Metrology (METAS).

Utilized in the Manufacturing of Nanoscale Components

According to Brian Gudauskas, the Application Manager at Hexagon, CMMs should achieve cost reductions high-accuracy results. He explains that this can be accomplished by adjusting the machining process based on measurement information.

This process is also applicable to nanoscale machining, which is considered to have reached its limits. In practice, Gudauskas' clients have utilized the Leitz Infinity's approximately 0.4-micron measurement capability for the manufacturing of nanoscale components.

Recommended Environments for the Leitz Infinity

The Leitz Infinity, positioned as a high-end model among CMMs offered by Hexagon, possesses the capability to accurately measure parts with complex shapes and tight tolerances, such as angular components and cylindrical gears.

The Leitz Infinity is recommended for research and development institutions where measurement accuracy is rigorously controlled and for manufacturers producing parts at the nano scale. As mentioned in the application cases, it is also suitable for companies providing measurement services.
