d. Select
d. Press “B”
e. Select Code 127
e. Press X or Z
f. Backlash Value = _ _ _ _
f. What is shown is the current value.
Follow the instruction on the screen
and press the appropriate soft keys.
Wait a few seconds between each
INCR VALUE or DECR VALUE
press.
g. The following is an example of what you
might see when running this code.
For example, if the up and down "Oscillation
Value" shown in the conversation line is .00278
millimeters, and the dial indicator is moving
back and forth .0012, then the true backlash
value is .00278 -.0012 = .00158 millimeters.
Input this by pressing MODE, SET UP, SERV
CODE, 128, SET and then .00158, SET,
RETURN.

The X backlash identified and stored in Step 2 should be less than 0.05 mm on a
new machine. If it is appreciably larger, inspect the drive train for loose bolts,
brackets, bearings, etc.
The backlash can also be found manually with a 0.002 mm indicator with the
following method.
Load the indicator to zero from one direction and zero out the DRO.
Move the indicator to 0.05 mm and then back to zero. Do not over shoot
0, otherwise start over.
Whatever number appears on the screen is the backlash value.
Enter this value into service code 128.
After entering this number redo the process. The DRO and indicator
should now both read 0.
CODE 128: Input Backlash Constant
Code 128 allows you to enter the backlash values for each axis. It displays the value
after it enters.
Be sure not to enter too much backlash on any given axis. Too much backlash in the
system may cause bi-directional repeatability problems or axis motor searching.
5.2.3 Lubrication
5.2.3.1
Headstock Lubrication
The SLX 1630 has a manual oil pump that is run off of the spindle through a
gear. One of the oil lines pumps oil to a site glass located on the headstock.
Periodically check to see that oil is flowing. For the SLX 1630, the oil should be
flowing when the spindle is on only.
A drain plug is found on the machine to drain the headstock. Oil can be added to the
reservoir by a plug in the top of the headstock cover or by removing the cover and
