Chapter 8 SXYX

!CAUTION

Always remove the grease nipple after completing the work. Damage or positional deviation could occur if the robot is operated with the grease nipple installed.

1)Prepare the following recommended grease nipple beforehand.

Recommended grease nipple A-M6X1 type (JIS B1575)

2)Turn the controller power OFF.

NOTE

When the ZF unit is attached for the 3rd-axis, the replenishment work can be carried out easier by moving the Z-axis slider to near the motor (near the origin) and turning the controller power OFF.

3)Place a sign indicating “Work In Progress” so that other operators do not turn the controller power ON.

4)Remove the stroke cover of the axis to which grease is to be replenished. (Refer to section "1. Installation" for details on removing the X-axis cover.)

5)Install the grease nipple onto the ball screw flange.

6)Using a grease gun, replenish grease from the grease nipple.

Sufficient grease has been replenished when new grease starts to seep out from the clearance between the ball screw nut and screw.

Wipe off any excessive grease.
