HM 1000/1250
9.3 Resetting the reference point for the Y axis (Y-axis stroke: 1250mm)
1) Insert the test bar into the spindle.
2) Put the block gauge (over 150mm) on the pallet deck, and install the indicator on it.
Then, set the height of the block gauge to "0".
3) Move the Y axis according to the calculation of the below formula.
Y axis coordinates = height of block gauge – (radius of test bar + 75)
For HM 1000, if the coordinates is Y0, the distance between table deck and center of the
spindle is 75mm.
(However, if the dimension of HM 1250's pallet is 1250x1250, the distance is 50mm)
Ex) If the height of the block gauge is 150mm, 150 - (30 + 75) = 45
Block Gage
4) Install the indicator on the top of the test bar and rotate the spindle while reading the
runout on the test bar. Stop rotating the spindle at an intermediate value of the runout.
5) Move the Y axis to set the indicator to "0".
6) Check the measuring value of the machine position (coordinates) displayed on the main
OP screen and compare it with the result of step 3 above. Enter the positive (+)
parameter if it's greater than the result of step 3, or the negative (-) parameter if less.
※ Parameter for the Y-axis reference point: NO. #1850 Y
▪ Add the above measurement to the existing parameter and press "INPUT", or add
the positive symbol (+) to the above measurement and enter "+INPUT".
▪ When you have changed the parameter, you must turn off the machine and turn it
back on.
7) Reset the reference point of the machine and repeat steps 1) ~ 6) above until the
measurement is within 0.05 mm.
▪ If the block gauge is not available, use a depth gauge or vernier calipers that can
measure the exact height between top of the test bar and pallet deck.
