Mahr 15-34 MarSurf Surface Measuring Instruments and Systems MarSurf Measuring Stand ST 750 D. Measuring Contours in New Dimensions Sketch UD 120 with ST 750 D Description Contour metrology from Mahr has been successfully used by hundreds of customers worldwide for decades. Due to many excellent customer solutions many of them patented contour metrology has undergone many important developments. Mahr was the first manufacturer of contour metrology offering the possibility of measurements with a twin stylus with simultaneous switching of the measuring force. This makes it possible not only to measure contours in one tracing direction but also to perform upside down measurements thus enabling pairs of opposed profiles to be recorded and set off against each other for diameter measurements for example. Today we are proud to present to you a decisive development that builds upon these possibilities. In connection with the measuring stand MarSurf ST 750 D the measuring stations UD 120 as well as XC 20 CNC can use the entire measuring length of 620 mm of the vertical axis. The greatly expanded measuring and evaluation possibilities result from the following basic principle and measuring procedure. 1. Measurement of the lower contour range "measuring force below" 2. Moving the slide on the measuring stand in the upper position. 3. Measuring the upper contour range "measuring force above" 4. Evaluation (distance diameter) of the two profiles related to each other By using a twin-stylus probe arm and the UD 120 LD 130 LD 260 or PCV drive unit the individual contour areas are measured using a measuring program. After the geometries of the upper side of the ring have been measured the slide of the measuring stand moves the drive unit down by the diameter range of the workpiece. Now the geometries of the lower side of the ring are measured. An exact computation of the travel path of the slide on the measuring stand enables the reference dimensions of the upper and lower contour to be related to each other. This enables the measurement of diameters distances and contours in the range up to 620 mm.
