2 MarSurf. Surface Measuring Instruments and Systems FROM THE THUMBNAIL TEST TO MARSURF. Wherever surface structures influence the function, processing or appearance of components or products, careful testing is essential. But how can surfaces be tested? At the beginning of the 20th Century, experts still had to test by eye and touch. A practiced eye can detect features in the μm range, and even the much maligned thumbnail test delivered perfectly acceptable results. Now however, we live in an age of exchangeable parts, fits and internationalization, where subjective tests like this are no longer adequate. Today, computer-aided measuring instruments provide objective data. Measurement and evaluation have become considerably easier. For decades, Mahr has been a worldwide pioneer in this area, as demonstrated by the company's numerous innovations and patented solutions in the field of surface roughness metrology. The interplay between the stylus, drive and measuring setup plays a key role in influencing the quality of surface measurement tasks. This is where Mahr's core expertise comes in, as demonstrated by the company's numerous innovations and patented solutions. Over this time, we have succeeded in perfecting the stylus method, which is now in widespread use throughout the world. We can meet even the most demanding requirements for non-contact measurement, e.g. where extremely soft materials or ultra-short measuring times are involved, thanks to the range of optical sensors offered in the MarSurf product family. Developed with Mahr quality, expertise and know-how, MarSurf is the solution for all your surface metrology needs.

In addition, further standard tracing arms of the MFW program are available for special measuring tasks. Technical Data Features PZK drive unit with integrated pick-up This Perthometer system consists of the small, handy PZK drive unit and the integrated inductive MFW pick-up. The tracing arm can be exchanged in a flash. The built-in datum plane enables not only standard skidded, but also skidless measurements. The well-known advantages of the MFW pick-up are the large measuring range, a high linearity and resolution. The measuring force, the design of the stylus tip and all technical details correspond to DIN/ISO standards. The traversing length setting is performed on the Perthometer. After the measurement, the pick-up automatically returns to its initial position.

For measuring stand operation, the support can be directly fixed to the mounting device on the measuring stand. In case of skidless tracing, two generously dimensioned knobs ensure sensitive and exact adjustment of both height and inclination. The positioning is facilitated by the pick-up height and inclination values being displayed on the Perthometer. For skidded tracing, the standard tracing arm protection is exchanged for one with a skid. An extensive range of accessories makes sure the PZK drive unit can be used for many different applications, e.g. measurements on cylinders with a dia. larger than 14 mm (.551 in) due to a Pair of vee-plates Order No or measurements on small cylindrical workpieces with a dia. larger than 2 mm (.0787 in) using a Front vee-block Order No PZK mounting device for measuring stand ST-D, ST-F, ST-G Order No

15 + MarSurf. Surface Measuring Instruments and Systems 15 GD 25 Drive Unit Whenever a measurement is started, the motor-driven height adjustment lowers the pick-up onto the workpiece. After the measurement the pick-up is lifted off and moved to a protected position. Then the return travel, which ends in the initial position, is carried out with the pick-up remaining in this protected position. Technical Data GD 25 drive unit Order No Description The GD 25 with its integrated datum plane stands out for its smooth traverse and low-vibration design. The housing, the bottom of which is in the form of a prism, is compact and robust. The GD 25 features a motor-driven height adjustment for lowering and lifting the pick-up and for setting it to zero automatically. Any single-skid, dual-skid or skidless pick-up of type M or R can be connected. In conjunction with the skidless pick-ups MFW-250 and RFHTB, roughness, waviness and form deviations can be assessed. With the GD 25, hand-held, desktop or measuring stand operation and measurements in normal or upside down position are possible. Due to its design, measurements can be taken inside tubes and bores. For diameters larger than 68 mm (2.68 in), the drive unit can be inserted completely, while for smaller diameters only the front part with its prismatic bottom and integrated pick-up protection can be inserted. The inclination adjustment screw aligns the datum plane with respect to the surface to be traced. The motor-driven height adjustment automatically changes the total position of the pick-up such that the stylus tip remains in the middle of the measuring range. With the support prism, the GD 25 drive unit can be used for plane and cylindrical workpieces. For diameters of up to 72 mm (2.834 in), it is centered on the continuous prism. For larger diameters and plane surfaces, the integrated support feet are used. For upside down measurements, the prism can be used for carrying cylindrical workpieces with diameters from 1 mm to 72 mm (.0394 in to in).

Surface Measuring Instruments and Systems PGK 120 Drive Unit Skidless tracing made perfect Description With the Windows evaluation software of MarSurf XR 20 / XCR 20 you can make full use of the advantages offered by the PGK 120 drive unit. All known optical and tactile pick-ups can be connected to PGK 120, e. g. pick-ups of the R series, skidless pick-up MFW, LS1/10 and Focodyn. Direct connection to Perthometer S2. In addition, PGK 120 can be connected to the old S3P/S4P Perthometers without needing an adapter and can be used up to 56 mm (2.2 in) traversing length. Features For 50 years Mahr has been defining the highest standards in surface texture metrology. Our products serve as a guidance to others. Especially Mahr's drive unit family is a class by itself a fact that is again proved with the new PGK 120 drive unit. Up to 120 mm (4.72 in) traversing length for all roughness and waviness measurements you can imagine Extremely low straightness deviation of the X-axis: < 0.3 μm/120 mm (< 12 μin/4.724 in) Hardly detectable - the residual noise: The residual Rz value is less than 30 nm (1.18 μin) Patented motor-driven pick-up zero setting within a range of 22 mm (.866 in) saving set-up work and time Automatic measuring runs: pick-up lowering - zero setting - measuring lifting Integrated in the drive unit: manual height adjustment of the pick-up within a range of 50 mm (1.969 in) Is a skidless pick-up required for transverse tracing?

18 18 MarSurf. Surface Measuring Instruments and Systems MFW-250 Skidless Pick-Up ,5 102,5 12,4 1,5 4 MFW ,8 13, ,6 Description Technical Data The convertible MFW pick-up for surface roughness and waviness measurements stands out for its large measuring range (± 250 μm/± in), high resolution (100, ,000 : 1), and low linearity deviation (< 1%). Double length tracing arms enlarge the measuring range to ± 500 μm (±.0197 in). The simple tracing arm interchange ensures a particularly wide field of application. The rugged, rigid design avoids natural vibration. In combination with the GD 25 and PGK 120 drive units, the MFW pick-up can be used as skidless or skidded pick-up. In combination with the PGK 120, the traversing directions can be varied. See the descriptions of MarSurf PGK 120. When using the MFW-250 in combination with the GD 25 drive unit and the Perthometer S2 or MarSurf XR 20 / XCR 20, the advantages such as the motor-driven height adjustment for lowering and lifting the pick-up automatically can be fully used. The special-design tracing arms described in the following are to be used purposefully. We recommend to consult our technical applications department.
