Periodic maintenance items

2. Monthly maintenance

This section describes the procedures for cleaning and lubricating the X-axis ball screw, guide and the Y-axis

guide and linear scale after cleaning them. The inspection items and cautions are given below.

Inspection items

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

Check if any fallen chips have adhered to the ball screw and 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 manually.

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 while referring “Cleaning and lubrication” described later on.

3. Contact YAMAHA sales representatives when abnormal sound is heard even after trying the countermeasures in the

above Steps 1 and 2.
