Mahr Federal (Providence, RI) has introduced a new "entry level" surface finish and contour measuring system that can generate both surface and contour measurements in a single pass. The MarSurf UD 130 replaces the MarSurf UD 120 and offers improved features, including nanometer range measurements, high measuring and positioning speeds, a biomimetic probe design with improved rigidity and higher dynamics and automatic probe arm recognition.
The UD 130 has measuring speeds up to 5 mm/second, a traveling length of 130 mm, Z-axis measuring range of up to 20 mm and resolution of 2 nm. The UD 130 utilizes an interferometric probe system that provides better technical data than the inductive probe systems of competitive systems. Probe movement is registered by photo diodes and evaluated electronically.
Probe arms are built using a bridge-truss design, which ensures maximum rigidity, reduced vibration and higher dynamics. Different probe tip geometries are available for different measuring tasks. Diamond tips with 2 µm and 5 µm radii can be used for roughness measurements, and ruby balls or carbide tips with 25 µm radii for contour measurements.
The magnetic mounting system allows probes to be changed by hand in seconds, and provides protection in the event of system collision. A ball stop assembly assures a repeatable probe mounting position, and an embedded electronic chip in the probe arm ensures reliable recognition. Plus, calibration data is saved, so probe changes do not require additional calibration.
