Measure the axial runout of
the spindle itself by:
Locate the DTI on the front
face of the spindle as shown on
the image.
Spin the lathe by hand.
The runout measurement
should be ranging between:
-0.02mm ~ +0.02mm
(-0.00079 ~ +0.00079in)
Any reading exceeding this
value will be exceeding the
standard tolerances.
