Resetting The Reference Point For The Z Axis (Z-Axis Stroke: 1600Mm) - Doosan DBC 130 II Installation Manual

DBC 130II
10) Move the X axis to set the indicator (currently contacting on the test bar) to 0.
11) Check the current position of the X axis from the "Machine Position" screen of the OP,
and figure out the difference between current position and "X1500.". Then, move the X
axis half of the difference.
12) Repeat step 5 above and move the indicator on the table deck until the gauge needle
contacts on the test bar where you set it to 0.
13) Repeat steps 8) to 9) above and adjust the runout until either sides of the test bar show
0.
14) If you get a satisfactory result, check the current position of the X axis from the
"Machine Position" screen of the OP, and enter the difference between current position
and "X1500." in the "parameter #1850 X" field.
※ To change the X-axis grid shift parameter
Read the machine position (coordinates) displayed on the OP screen. Enter the
positive (+) parameter if the result of deducting half of the X stroke (1500) from the
machine position is a positive value; enter the negative (-) parameter in micron (μ) if
the result is a negative value.
Add or deduct the above measurement to and from the existing parameter and enter
"INPUT", or enter the result plus the symbol, and press "+INPUT".
▪ Parameter for the starting point of the X axis: NO. #1850 X
15) Return the X axis to the reference point manually and repeat the instructions above
until the result falls below 0.005mm.

16.3 Resetting the reference point for the Z axis (Z-axis stroke: 1600mm)

(1) Refer to "Reference point for X axis" above to

the indicator to "0".
▪ The machine position is "X1500. Z290.W0",
and around "Y400" for the Y axis.
2) Return the Z axis to the reference point
manually.
3) Rotate the B axis by 90 degrees.
4) While moving the Z axis, set the indicator to
"0".
