Leitz Infinity

Leitz Infinity - Most accurate CMM within its class

For the Leitz Infinity, Hexagon Manufacturing Intelligence drew on the whole of their long-standing experience, optimizing the latest technical developments to create a new UHA CMM boasting the highest available accuracy within its class. The Leitz Infinity achieves measurement results which are excruciatingly exact.

For very challenging measurement tasks and the highest precision in quality and process control, the Leitz Infinity coordinate measuring machine has been designed with extremely accurate probing.

The high accuracy of the Leitz Infinity makes it possible, in the production, to make the correct decisions and to keep the cost of producing parts at a minimum. A high parts throughput is achieved from the dynamic single-point probing and the serial High-Speed-Scanning (HSS) of known and unknown contours.

The Leitz Infinity carries out any measurement task with the highest precision regardless of whether on prismatic workpieces or parts with highly complex geometries - such as cylindrical or globoid stepping gears. In particular, part measurements with very close tolerances require a coordinate measuring machine like the Leitz Infinity for the highest precision.

LSP-S4 Probe Head
With horizontal probe extensions of up to 800 mm length the continuous High-Speed-Scanning probe head LSP-S4 allows the measurement of features deep inside a work piece. Its integrated automatic weight balance system can carry styli configurations of up to 1000 g.

In addition to its ability to accept long styli, the LSP-S4 excels with its low trigger forces - ideal for measuring delicate surfaces. Its long travel means that the LSP-S4 is not susceptible to damage caused by collisions.

Probing deflections are measured via high resolution Linear Variable Differential Transducers (LVDT). The LSP-S4 supports all the standard probing modes like Single Point Probing, Self-Centering as well as Continuous High-Speed-Scanning for fast and accurate form and profile measurements.
Like all other Leitz probe heads, the LSP-S4 provides simultaneous and unclamped probing in all axes, always orthogonal to the surface. This allows the correct compensation of any styli deflection.

Leitz Precitec LR Optical White Light Sensor
As an option or addition to the 3D probe head the Leitz Precitec LR Optical White Light Sensor is available. This sensor uses a chromatic confocal measurement method and is ideal for applications in the area of lenses (glass, plastics), surfaces and profiles.
