4.4. Adjustment after replacing the ball screw
The coordinates of the machine deviate due to the replacement of the parts. Therefore, some works
need to be done in order to restore the coordinates in the simple method.
Caution:
Please make sure to do the necessary work before replacement. Otherwise, you will need to perform
all the adjustment, which requires a great deal of time later on.
<Works to be done>
• Adjust the machine reference and the initial position of the W-axis.
• Check the peak current (With the “Servo utility”).
* Please refer to the relevant section in “5. Adjustment”.
Check if the bolts are tightened properly
1. Press the [Emergency stop] button and check the surrounding area for safety.
2. Check the bolts removed for replacement or loosened are tightened properly.
Check if the bolts are tightened with the appropriate hex wrench and make a mark on the
bolts with the marker pen.
Other items to be checked and done
1. Check if there are any tools used for replacement left in the machine.
2. Check if there are any pieces of cut off cable tie left in the machine.
3. Make sure that all the harnesses are secured properly, and no axes interfere with anything
when they move.
Caution:
Please do not use an air gun for cleaning inside the machine. The blown away dusts may stick to the
moving parts of the axes, which causes the serious problem to the machine.
4. Get ready for the production activity
Put back all the removed parts such as feeders and other supplying equipments to the
original position.
