With the new, extremely precise and fast measuring station MarSurf LD 140/LD 280, Mahr provides an automated solution to measure roughness and contour at the same time and with the highest accuracy. This saves customers time and money: on one hand, they save time as they receive two measurement results with just one measurement run; on the other hand, they save money as they only need to invest in one measuring station.
To achieve simultaneous measurement of roughness and contour, the device is equipped with a newly developed tactile sensing system. Its probe arm unit captures the measurement data only once, which the software can then evaluate twice, both for contour and roughness features, if desired. This process measures workpiece contours, straightness, and surface deviations using the tactile cutting method.
Available in eight device variants
The device is available with two different X-axis options – travel and measuring range of 140 or 280 millimeters – 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 levels of automation. This allows the customer to always select the precisely fitting measuring station for their individual requirements. The comprehensive portfolio of probe arms of various sizes and designs also qualifies the MarSurf LD 140/LD 280 for diverse measurement tasks at different measuring points. In geometric measurements, the probe arms ensure the highest safety and precision due to their high stiffness.
Industries and Application Examples
Wherever users want to evaluate small tolerances in the micrometer range or larger tolerances in a very small area, the MarSurf LD 140/LD 280 is the device of choice. Typical measurement tasks can be found in the automotive industry, for example, on crankshafts, camshafts, connecting rods, engine or transmission components such as drive shafts, in mechanical engineering on bearing races or hydraulic components with very small and precise edge breaks, in the aerospace industry, for example, on turbine components, and in the optical industry, especially with lenses and aspheres. Since the tolerances in the measurements performed are usually very small, it is advisable to set up the device in a climate-controlled measuring room.
Additional advantageous features
Additional product specifications make the MarSurf LD 140/LD 280 a future-proof investment with the latest technology. The device features extremely fast and precise positioning axes. Thanks to the large flexible grid plate, clamping positions are reproducible, which reduces setup times. Additionally, the probe arm unit can be easily changed manually without tools, as it is magnetically attached to the sensing system. Furthermore, a chip integrated into the probe arm ensures unambiguous probe recognition and automatic probe force adjustment. The operation of the MarSurf LD 140/280 is done via the proven MarWin software or the improved handheld control panel MarControl connected to the controller. The software includes an assistant for calibrating the probe arms, which, in combination with a motorized TY-axis, enhances user-friendliness.
