The calculated value "Vr" is the offset measure of the tailstock. The offset is monitored with the
gauge (also the return travel).
For this type of cone machining the lowest speed is used !
Annotation:
In order to check the position of the tailstock axis to the rotation axis, a shaft with two centering-
sis clamped between the points. The stand with the gauge is put on the bedslide. The gauge is
aligned 90° to the rotation axis and horizontally brought into contact with the shaft. The gauge
will pass along the shaft with the bedslide. There must not be any travel of the pointer along the
whole length of the shaft. If a deviation is being shown, the tailstock is to be corrected.

Calculation:
or
The tailstock offset must not exceed the value
"Vrmax"
