MarSurf CD 140 AF (Contour measuring station)
• MarForm MMQ 400 is suitable for universal use for extensive workpiece
evaluation according to DIN ISO 1101.
• High-precision measuring axes in Z and X make every form measuring
task possible. There are MarForm MMQ 400 versions available for
• High-precision workpieces
• Unusually long workpieces
• Large and heavy workpieces
• Use in production or in inspection rooms
• Choose from a range of modules available to optimally customize the
MarForm MMQ 400 to your requirements:
• Motorized or manual centering and tilting table
• Vertical axis (Z) with a 900 mm, 500 mm or 350 mm measuring length
• Horizontal axis (X) with a 180 mm or 280 mm measuring length and
with digital linear scales in axes X and Z. For measurements where
finding the exact, reproducible measuring position affects the result
• Manual or fully automatic probe with short measuring circle, high
linearity, low measuring force.
• Path control for quick measurement of a nominal contour
• optionally with motorized tailstock for shafts longer 200 mm
• Roughness measurement
• Switch between form probe with ruby ball and roughness probe PHT 6– 350
• Piston testing with MarWin Evaluation Software
• Shaft twist testing and analysis with MarWin
• Cam profile testing
• Bar to bar variation analysis at commutators
• Contour measurement and evaluation
• Path control (MCPC)
• Free form evaluation
• Vibrational velocity analysis
• Dominant roundness waviness (MBN 10455)

Note
* Values as maximum deviation from LSC reference circle, filter 15 undulations/revolution.
** All values in accordance with DIN ISO 1101 at 20°C ±1°C in a vibration-neutral environment, filter 15 undulations/revolution LSC or 2.5 mm LSS, 5 rpm or 5 mm/s and standard
probe arm with ball diameter 3 mm. Proof at the standard using error separation techniques. Given the number of different options available, only a few machines are described
here by way of example. Technical data for “your” MMQ is available from Mahr on request
