6. Machine Accuracy Measurement and Adjustment
- X plane
① Measurement
Place a straight edge by laying down on the table in the Y-axis direction, set the
indicator to “0” at both ends of the straight edge by setting up an indicator on the
spindle head, and then measure the maximum difference (i.e. measurement in the
middle) while moving the Y-axis.
▪ With this method, set one end to “0” and hit the other end slightly with a driver
handle, etc. while pressing the setting area with one finger. Both ends should be
adjusted to “0 ” and the value for the center taken as a measurement value.
※ If a Straight Edge has not been prepared, measure both ends and the center on
the Y-axis plane of a square ruler instead, when measuring the X-Y squareness.
▶ Measurement position : Both ends and the center of the straight edge side.
▶Tolerance : 0.005mm / 300mm
② Adjustment
If the straightness on the Y-X plane of the Y-axis is wrong, an irregularity of the
machine feed level could be a possible cause, in which case re-leveling should be
performed by referring to “Machine Level Operation.”
▪ If the problem is not resolved by re-leveling as mentioned above, a Y-axis LM
Guide defect or an LM Guide misalignment could be another possible cause, in
which case it will be necessary to replace or re-align the LM Guide to resolve the
problem.
