Application: Piston measurement and analysis

For use in conjunction with MarForm MMQ 400,  with the T7W probe and with Mahr's MarWin evaluation software, comprising:

  • Piston measurement and evaluation software package based
    on the MarWin evaluation software

 Probe arms for T7W, optimized for piston measurement, are available as an optional accessory pack.



Alignment of piston
Fully automatic piston centering and levelling

Measuring the external piston profile
Measurement in the piston pin bore to determine the position of the piston pin bore axis
Measurement of ovality form
Measurement of meridian form

Measurement of piston groove

Measurement of piston pin bore
Measurement of polar bore form
Measurement of linear bore form

Evaluation and recording


Evaluation of ovality form
Tolerance band evaluation (ovality infeeds) at any distance [°]
Angle between oval main axis and bore axis at measuring height
Calculation of head offset in X and Y
(gives the offset between an oval and the piston axis).

Evaluation of meridian form
Tolerance band evaluation (linear infeeds) at any height [mm]

Evaluation of groove measurement

Evaluation of radial lines

Angle between profile and reference plane
Total angle between upper and lower flank
Straightness of measured radial lines

Evaluation of end-face circles
Flatness of profiles with filter 0 - 50 [W/U]
Flatness of profiles with filter 15 - 150 [W/U]
Evaluation of piston pin bore
Evaluation of piston pin bore (linear) with tolerance band evaluation (linear infeeds) at any height [mm]
Evaluation of piston pin bore (polar) with tolerance band evaluation (ovality infeeds) at any distance [°]
Rotation of bore oval axis relative to position of turn table
