Loosen bolts
Avoid moving the machine horizontally. If any foot comes off the ground when
loosened, suspect soft foot.
Shim feet accordingly
Shimming usually involves the jacking up of the machine and inserting or
removing shims of known thicknesses. (Some shims have the thicknesses
indelibly etched on them.)
Use the vertical foot correction values to shim BOTH front and back feet as
required. Negative feet correction values indicate that the respective machine
feet are high and therefore shims should be removed, while positive foot
correction values suggest addition of shims.
Note
Vertical shimming can also be carried out using live vertical Move.
Retighten bolts
The machine should now have good vertical alignment.
Re-measure
Re-measure to verify vertical alignment results and determine the exact
alignment condition.
Horizontal live Move
Horizontal Move is used for the lateral positioning of the machine. This used to
be done with a dial gauge at the machine feet, but with the 'Move' function, live
horizontal movement is viewed on the display screen.
