PROVIDENCE, R.I. - Mahr Inc. in Providence, R.I., introduced the MarSurf LD 280 measuring station, an automated dimensional metrology system that simultaneously performs roughness and contour measurements using a single probe.

The MarSurf LD 280 uses the stylus measurement method to evaluate workpiece roughness, contour, and waviness in a single measurement run. Company officials said the approach is intended to reduce inspection time and equipment costs by combining two measurement result types into a single measuring station.

The system is available with manual or motorized TY-axis positioning for part crowning and positioning applications, motorized Z-axis configurations at 350- or 600-millimeter heights, and X-axis travel lengths of 140 or 280 millimeters. The configuration options create eight device variants with different levels of automation.

Mahr officials said the system's probe arm portfolio enables a broad range of measurement applications, including automotive crankshafts, camshafts, connecting rods, engine and transmission components, bearing raceways, hydraulic systems, and aviation turbine components.

The MarSurf LD 280 incorporates fast positioning axes and a flexible grid plate intended to provide repeatable clamping positions and reduce setup and cycle times. The probe arm unit attaches magnetically and can be exchanged without tools.

An integrated chip within the probe arm allows the system software to automatically identify the installed probe arm and configure probe force settings without recalibration. Calibration data also transfers automatically between probe arm changes, according to the company.

Operation and evaluation functions are performed through Mahr's MarWin software platform, which includes an automated probe-arm calibration wizard designed to improve usability when paired with the motorized TY-axis configuration.

Nick Russo, product manager for Mahr Inc., said the MarSurf LD 280 is intended to streamline industrial measurement workflows while maintaining high-accuracy inspection capabilities across multiple manufacturing sectors.
