Periodic maintenance items

2.2 Inspecting each axis

Inspect the ball screws on the X, W, U, and PU (Push-up) axes and the guides on the X, Y, W, and U axes. The

checkpoints are listed below.

A grease spattering prevention cover is attached to the X-axis ball screw. Before starting the inspection work,

detach this grease spattering prevention.

TIP

See "3.1 Cleaning and greasing the X and Y axes" described later on for detaching or attaching the anti grease

splatter cover.

TIP

See "3.1 Cleaning and greasing the X and Y axes", "3.2 Cleaning and greasing the push-up axis (PU-axis)", "4.7 Dual

stage only: Cleaning and lubrication of U axis (W2 axis)" and "5.2 Cleaning and lubricating the W-axis" in this chapter,

and "Chapter 5 Lubrication points and schedule" for positions of ball screws and guides of each axis.

Checkpoints

1. Any foreign matter adhering to the ball screws and guides?

Check if any fallen chips have adhered to the X and Y axis ball screws and/or X, Y and W axis guides.

2. Do the ball screws and guides have the correct amount of grease?

Check if grease has flowed off or splattered in the air failing to adhere. Also check if grease has discolored or hardened.

3. Any abnormal sounds from the ball screws?

Press the emergency stop button. Then check for any abnormal sounds while pressing the X-axis by hand.

Countermeasures

1. Ball screws and guides may be damaged when chips and other material bite into them. If chips are adhering, wipe

them off along with the grease or remove with tweezers, etc.

2. Apply grease referring to "3.1 Cleaning and greasing the X and Y axes", "3.2 Cleaning and greasing the push-up axis

(PU-axis)", "4.7 Dual stage only: Cleaning and lubrication of U axis (W2 axis)" and "5.2 Cleaning and lubricating the

W-axis" in this chapter described later on.

3. Contact YAMAHA sales representative when abnormal sounds occur even after trying the countermeasures in the above

steps 1 and 2.
