Checking method
(1)
Mount the gauge (SKN0003) on the revolving nosepiece.
(2)
Use the stage insert plate as the reference.
(3)
Using a 0.07 mm thickness gauge (OT1949), check the clearance between the gauge
(SKN0003) and the stage mount.
(4)
The result is acceptable if the thickness gauge does not go though the clearance
between the gauge and the stage mount.
(5)
Set the gauge in the front-rear and left-right directions.
(6)
If the result is not acceptable, insert tin foil between the stage mount and the frame
until the specification is met.
