■ Remarks for lubrication on X/Y axis ball screw

NOTE: Insufficient amount of grease or remaining of old/dirty grease may cause axis damage or axis noise

problem. Basically lubrication should be performed every two weeks, but it is recommended to

check grease condition in proper intervals depending on the machine’s running time and it’s

environment to perform lubrication if necessary.

Follow the procedures below for lubrication.

■ Lubrication Points with Grease Nipples

ACTION:

① Wipe off the dirty grease or adhered grease on the ball screw. Use a nonwoven cloth to wipe, not a

cotton swab or woven cloth that may generate dust or waste threads.

② Push the grease gun to the grease nipple and apply grease in the ball screw nut.

③ Perform “Ageing” in Manual > Warm Up with the less than 20% axis speed for more than 10 minutes.

Speed setting can be done by sliding the “Axis Speed” gauge at [Setting] tab.

④ Then wipe off the pushed-out dirty grease with a nonwoven cloth and apply new grease into the nut

again.

⑤ Remove excessive grease gathered on the nut or both ends of the ball screw with a nonwoven cloth,

and perform “Ageing” by increasing axis speed gradually.

⑥ By Axis command in Manual Menu, move the Head Assy. from an end of axis to the other end for

several times, so that the applied grease is spread over whole of work range. However, the spread

grease cannot reach the actual end of each axis because of the out of work range of the nut. Then add

some grease there by hand with a nonwoven cloth etc.

NOTE: If a cotton-swab or a woven cloth is used to wipe off the dirty grease, waste threads of cloth may be caught

in the ball screw. Use a nonwoven cloth.

NOTE: Use proper grease for lubrication, specified as our standard. (See the “Specified Lubricants” list at the end

of this chapter.)

NOTE: Remove the excess grease gathered on the nut or both ends of the ball screw by wiping it off with a

nonwoven cloth to avoid grease scattering.
