The MarSurf LD 140/LD 280 measuring system from Mahr measures roughness and contour automatically and with high accuracy. This saves customers time, as they receive two measurement results with one measurement run. But they also save money, as they only have to invest in one measuring station. The device is equipped with a newly developed tactile probe system to enable the simultaneous measurement of roughness and contour.
Measuring using the stylus method
The probe arm of the MarSurf LD 140/LD 280 only records the measurement data once, which the software can then evaluate twice for both contour and roughness features if required. This process measures workpiece contours, straightness and surface deviations using the stylus method.
Available in eight device variants
The device is available with two different X-axes - travel and measuring path 140 or 280 millimetres - with manual or motorized TY-axis as well as with a Z-axis in two heights. The combination of these features results in eight device variants with different degrees of automation. This means that the customer can always select the measuring station that meets their irequirements. The comprehensive portfolio of probe arms of different sizes and designs also qualifies the MarSurf LD 140/LD 280 for a wide range of measuring tasks.
Industries and application examples
The MarSurf LD 140/LD 280 evaluates small tolerances in the micrometer range or larger tolerances in a very small range. Typical measuring tasks can be found in the automotive industry, for example on crankshafts, camshafts, connecting rods, engine or transmission components, in mechanical engineering, for example on bearing raceways or hydraulic components with very small and precise edge breaks, in the aviation industry or in the optical industry. As the tolerances for the measurements are usually very small, it is advisable to set up the device in an air-conditioned measuring room.
