Mahr 16-16 MarForm Form Measuring Instruments MarWin. Lead Measurement and Analysis with MarForm Formtesters Expansion package for MarForm Formtesters as per Mercedes Benz Standard MBN31007-7 version 2 Description Measured value acquisition The surface structure of the sealing surface of a shaft influences the flow behaviour of the fluid that is to be sealed and therefore greatly influences the sealing function. A lead structure on the sealing surface can interfere with both the shaft surface fluid and sealing lip contact length creating leakage due to a conveying effect. Lead is a surface feature appearing over the entire circumference on rotationally symmetrical surfaces. The evaluation of the macro lead is conducted with the option "Lead measurement" as per the Mercedes Benz Standard 31007-7. Measurement of n generating lines (72 as per MB Standard MBN 31007-7) A T7W probe arm with two styli is used to assess the measuring values. Stylus 1 with 3 mm hard metal ball for mechanically centering and tilting of the workpiece on the Formtester Stylus 2 with diamond stylus tip for measuring lead and surface roughness parameters Scope of application External measurement on workpiece diameters between 2 and 200 mm Expansion package Lead measurement and analysis For use on MarForm MMQ 200 MMQ 400-2 MFU 100 with motorized probe T7W and the Mahr evaluation software MarWin consisting of Software package "Lead mesurement and analysis" based on MarWin evaluation software T7W probe arm unit for lead measurement double-ended with diamond tip 5 m and 3 mm hard metal ball for alignment (5400234) Order no. 5440675 mi Request a brochure or see WebCode 1292.
