Mahr positions the MarSurf CNC modular Evo as an entry point to automated surface roughness measurement. The measuring station adds a 280 mm feed axis to the MarSurf CNC modular platform and ships with the MarControl control unit as standard. Mahr calls it an "automation with a sense of proportion" option for shops that want CNC-based roughness measurement without buying a large, fully automated system.
Repeatability is the key word here. Automated sequences hold measurement conditions constant and reduce operator influence, which Mahr says improves the reliability of results and shortens cycle times. The company also says the interface is built for use on the shop floor, so production staff can run recurring, standardized checks and free up the lab's metrology systems for other work.
For a quality manager weighing whether to take roughness checks out of the hands of individual operators, the draw is a smaller step than a full automation cell. Mahr says the station handles complex workpieces with numerous measurement points, parts in different spatial orientations, rotationally symmetric parts at various angular positions, and simple pallets.
The hardware builds on the existing MarSurf CNC modular line. Positioning axes with 200 mm of travel carry over, along with compatibility with all feed devices and the broader accessory portfolio. The 280 mm axis extends the measuring volume for larger parts. Mahr says existing accessories and workpiece holders can stay in service, so shops already running MarSurf CNC modular stations keep their fixtures.
Mahr also plans to offer the Evo as a preconfigured station. The configuration is fixed at the factory in three variants: one linear axis, one linear and one rotary axis, or two linear axes and one rotary axis. The company says this cuts coordination effort during planning and removes manual assembly at the customer's site.
