ball screw and guide, and Y-axis guides and linear scales. The inspection items and cautions are
given below.
►
Inspection items

Check if any fallen chips have adhered to the X and Y-axis ball screws and/or X, Y and W-axis
linear guides.
2. Do the ball screws and linear 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.
e
3. Any abnormal sounds from the ball screws?
Press the emergency stop button. Then check for any abnormal sounds while pressing the X-axis
