(1) Mount the tool (J18001-1) on the surface plate as above, then set the dial gauge to "0".
(2) From "0" position of (1), turn the index circle in the direction of the arrow so that the needle is on 18 (0.18mm)
position. (This position is "0" position of D90.)
(3) Measure the body back based on "0" position of the index circle.
1.82-1.82
＝
0
So this is within
standard.
e.g.
(1) Mount the tool (J18001-1) on the surface plate as above, then turn the digital gauge ON and press [ZERO/
ABS] button so that the value becomes "0".
(2) Measure the body back based on "0" position
(3) Subtract "1.82mm" from the measured value. If the value is "0±0.01 mm / Parallelism: 0.015mm or less",
it is within standard.
