Finish Level and Tram the Machine
Note: This procedure is duplicated as part of the startup checklist enclosed. Please
make note of the final tram readings on the startup checklist forms to be returned to
Milltronics.
1. Center the table in the travels of both the X and the Y-axes.
2. Adjust the center leveling pads so the machine is resting on only the 4 corner pads
3. Use a precision level placed on the center of the table and adjust the pads until the
machine is level side to side firmly setting on the 4 corner pads.
4. Rotate the level 90 degrees on the table (or use two levels) and adjust the pads until
the machine is level front to back.
5. Re-check the side to side level again as it may have changed while adjusting front to
back. Repeat steps 6 & 7 until the machine is level in both directions.
6. Using a magnetic base with a dial indicator sweep the table to check tram. The tram
should sweep within .001” over a 10” diameter sweep. Adjust leveling pads if
necessary. At this stage it is more important to be level to tram and NOT level to the
precision level.
7. Extend the center pads to the floor. The center pads should have light pressure
applied to them. Be careful not to affect the level or tram while adjusting them.
8. With the level placed lengthwise along the table checking the X-axis level, move the
Y-axis in and out. If there is any twist in the Y-axis, the bubble will move as Y travels
in and out. Ideally there is no twist and the bubble will not move. If it does move, go
back through the process and re-level the machine.
