Q1: What should be done if there is abnormal noise during machine operation or it cannot operate?
A: First determine if the abnormal noise is throughout the entire operation (go to Q2) or if it is at the motor end (go to Q13), (if unable to operate, go to Q30).
Q2: How should one handle if it is determined to be abnormal noise throughout the entire operation?
A: Check if basic maintenance has been performed.
Q3: What are the key points of basic maintenance?
A: Rail (slider) > Screw (ball screw nut) > Angular contact bearing (FK).
Q4: How should one handle if it is determined that there is an abnormality with the rail (slider)?
A: First, check if there is any collision between the rail and slider.
Q5: What should be done if there is no collision between the rail and slider?
A: Check if the screws are tightened. If tightened, check if the alignment is shifted.
Q6: What should be done if there is no abnormality with the rail (slider)?
A: Check if the balls inside the slider are damaged.
Q7: What should be done if there is no abnormality with the rail (slider)?
A: Check if there is any abnormality with the screw (ball screw nut).
Q8: What are the key points to check with the screw and ball screw nut?
A: First, check if the screw is rusted or scratched on the surface. For the ball screw nut (go to Q9).
Q9: What should be done if there is no abnormality with the screw?
A: Check if the balls inside the ball screw nut are damaged. If not damaged, check if the alignment is shifted.
Q10: What should be done if there is no abnormality with the screw (ball screw nut)?
A: Check if there is any abnormality with the angular contact bearing (FK). The key points to check with FK are the same as for the angular contact bearing.
Q11: What are the key points to check with the angular contact bearing?
A: First, check if there is any foreign object jamming the angular contact bearing. If no foreign object jamming, check if the balls inside are damaged.
Q12: What should be done if there is no abnormality with the angular contact bearing?
A: First, check if there was any misalignment during installation, if the screws are tightened properly, and if there are any damaged balls inside.
