Straightness Of Z Axis - Doosan HM 1000 Installation Manual

HM 1000/1250

10.1 Straightness of Z axis

1) X-Y
ⓐ Measure
Install the level on the grinding side of the
column in the X-axis direction and set the
reference point. Feed the Z axis in 3-
divided stroke and check the greatest
difference of the level changes.
▪ Measuring point
: Z0. Z625. Z1250.(Z0. Z750. Z1500.)
▪ Tolerance: 0.025mm / full stroke
ⓑ Correction
Incorrectness of the X-Y straightness of the Z axis is thought to be attributed to an
error in the machine feeding level. So refer to "Machine Leveling" later in this
manual and perform the leveling again.
2) Y-Z
ⓐ Measure
Install the straight edge vertically on the
pallet in the Z-axis direction and install the
indicator on the spindle head. Set either
end of the straight edge to "0" and move
the Z axis to check the greatest difference
(measurement in the middle of the
movement).
※ If the straight edge is not available, use
the top side of the square that is required
for measuring the squareness between
Y and Z axes.
▪ Measuring point: both ends and center of straight edge
▪ Tolerance: 0.005mm / 300mm
ⓑ Correction
Incorrectness of the Y-Z straightness of the Z axis is thought to be attributed to an
error in the machine feeding level. So refer to "Machine Leveling" later in this manual
and perform the leveling again.
