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.
