Workpiece Measurement High-precision measuring system checks microcomponent quality
At Control in May, Mahr displays the Precimar 826 measuring station for microcomponent measurement. This test device enables medical device manufacturers to examine the smallest spheres, plates, cones or cylindrical parts for production quality.

An application specialist in measuring technology, Mahr has developed a new measuring concept for examining microcomponents that operates not only with high precision but also cost-effectively. Just like bigger workpieces, very small products such as 1-mm platelets no thicker than 0.1 mm, spheres as small as 0.1 mm in diameter, and 1-mm-long high-precision internal tapers must be tested for quality. But until now, these small parts have been measurable only with a great deal of effort and relative imprecision, as it was impossible to secure them properly on conventional measuring stations.
The Mahr concept breaks new ground. Here, no attempt is made to clamp the tiny parts. Instead, they are reliably secured on the measuring machine in a different way, which allows small workpieces to be contacted in a reproducible manner and thus be reliably measurable.
The Precimar 826 offers the user the necessary submicron measurement accuracy. Specifically, it can be accurate to 35 nm. For all its precision, the Mahr system is said to have an attractive price-to-performance ratio.
