Replenishment methods

Refer to the following procedures and replenish the grease.

1)Remove the stroke cover of the axis to which grease is to be replenished.

2)Replenish the grease with one of the following methods.

!CAUTION

Always remove the grease nipple after replenishing the grease. Failure to do so could cause damage if the grease nipple and robot interfere.

Method 1: Install the grease nipple onto the M6 tap hole on the ball screw flange surface, and replenish grease using the grease gun.

Sufficient grease has been replenished when new grease starts to seep out to the screw shaft.

Wipe off any excessive grease.

Recommended grease gun : MG70 (THK H-type nozzle)

Method 2: Wipe off any grease adhered on the ball screw with a rag, etc., and directly apply grease into the ball screw slit with a finger.

NOTE

Due to the structure, the X-axis and ZH can be greased only with this

method.

3) Return the stroke cover to the original position.
