Mahr at EMO 2025: Digital and optical measurement technology
Mahr is showcasing cutting-edge technology for automated measuring technology at the world's leading trade fair EMO in Hanover. The focus is on solutions that make manufacturing processes more efficient, smarter and more sustainable along the entire value chain, including 24/7 operation.
Mahr's trade fair appearance at EMO (September 22 to 26, 2025) will focus on high-precision tactile and optical measuring systems that can be seamlessly integrated into modern Industry 4.0 manufacturing environments and thus make a decisive contribution to increasing productivity, quality and Overall Equipment Effectiveness (OEE). One of the trade fair highlights is the MarSurf MC 510, an innovative automated solution for measuring surface roughness on workpieces directly in the CNC production machine. The measuring device is completely integrated into the tool holder, where it measures by means of a vibration-resistant, tactile free-probing system - in compliance with standards and with high accuracy down to Rz 1 µm. Visitors to the DMG Mori stand can see the measuring device in a live demo. The high-performance Mar4D PLQ 4200-T4 cylinder coordinate measuring machine exhibited at EMO measures complex rotationally symmetrical workpieces extremely flexibly and conveniently, making it ideal for smart manufacturing environments. As a new optional feature, Mahr now offers a sensor for automated workpiece temperature compensation for maximum measurement reliability and repeatable measurement results - completely without operator influence.

Mahr will also be presenting a product that works with the unique scattered light technology at its stand D25 in hall 5: The MarSurf3D OptoShaft TT allows the processes involved in grinding and finishing bearing seats to be monitored and controlled in real time. Even the smallest ripples with amplitudes < 0.05 μm lead to intolerable noise. Thanks to the flexible measuring device, tool monitoring and rapid detection of machine faults are now possible. Mahr has repositioned its optical 3D measurement technology: Customers can now put together the right system for their own measuring tasks from a wide range of possible combinations. The result is an individual, customized measuring station. At EMO, Mahr will be presenting the MarSurf3D SX platform with MarSurf MS+ multi-sensor measuring head. The MarSurf3D SX platform shows its strengths with smaller workpieces with axis sizes up to a maximum of 200 mm. It has a compact design and integrated damping. The MarSurf MS+ multi-sensor measuring head offers maximum flexibility as it combines the three technologies confocal, white light interferometry and focus variation. This allows users to perform all surface measurements down to the lower nanometer range in real time with a single device. From its portfolio of stationary surface measuring devices, Mahr will be showing the MarSurf SD 140 BG 12 with 140 mm scanning distance and motorized TY axis, which can inspect both roughness and contour features - in just one measuring pass thanks to the newly developed tactile probing system.
