9.4. Adjusting the play of the guides

9.4.1. Adjusting the play of the guide of the cross slide

Even if the guides are regularly oiled, cleaned and properly
adjusted, the guides will show play after some time.
1. Release the counter nuts 1 (Fig. 18) of the
adjusting screws for upper carriage 2, turn in all
adjusting screws 3 evenly until the play is
eliminated and then retighten the counter nuts.
Please note:
The guide can be clamped with the screw 4.

9.4.2. Adjusting the play of the guide of the support

1.
Repeat the same procedure for the cross slide 4.
Note: The guide can be clamped with the help of
screw 5.
2.
Turn the machine upside down and unscrew the
threaded pin 1 (pic. Right) somewhat.
3.
Lightly retighten clamping screws 2 to reduce play.
4.
Check if the support can still be moved easily. The
drive motors could stall if the support is too stiff.
These will then emit "peeping" noises. In this case,
increase play somewhat.

9.5. Main spindle

The bearing assembly of the spindle through 2 taper rolling bearings is maintenance-
free for at least 6,000 hours at minimum speed and 1,800 hours at maximum speed. If
there is a small amount of play after this time, the bearings can be readjusted by a
specialist or in our central service.
