REVO® valve seat and guide measurement
The measurement of valve seat and guides has traditionally been very challenging, involving time-consuming methods that often do not provide a sufficiently capable measurement.
REVO and Renishaw's Renscan5 technology change this situation dramatically.
REVO makes now possible to collect very quickly large amounts of data, from which the analysis parameters for both the valve seat and the valve guide features can be calculated. The method performs exceptionally well in repeatability and reproducibility tests.
Data collection process takes approximately 20 seconds!
The measurement process involves two helical scans, one on the valve guide bore and the second over the valve seat area. On the guide a single helical scan is used with a typical pitch of 0.5 mm, at a scanning speed of 150 mm/s.
This valve seat scan uses REVO's adaptive scanning capability, which allows a single scan command to cover the areas above and below the critical valve seat surfaces. On the valve seat a single helical scan is used, with a typical pitch of 0.1 mm, at a scanning speed of 500 mm/s.
The valve seat and guide analysis utility that is embedded in Renishaw's MODUS™ metrology software is used to evaluate the scan data and return the attributes listed below:
Please note that Renishaw provides this analysis facility to other metrology software providers that support the REVO system.
