Gear and spline inspection instruments of the type VP feature a face stop. During inspection there is no need to find the reversal point. This ensures a stable measured value. Test items with suitable plane surfaces are placed onto a table-top. Inspection is always carried out at right angles to the workpiece axis. VP inspection instruments are characterised by their flexibility. In the following is a list of the advantages:
Stable measured value,
Only minor operator influence during the inspection,
Easy adjustment of the measuring force,
Quick change from internal to external gearing,
Quick change from large to small gearing diameters,
Software evaluation is possible,
Longitudinal dynamic type gives information about the whole length of the face width. Form errors, such as crowning, conicality and roundness are visible.
