To check ball screw backlash, measure the amount of play or movement between the ball screw and the nut.

• Use a dial indicator to measure the amount of axial play in the ball screw.

• Check for any abnormal noise or vibration during operation, which could indicate excessive backlash.

• Inspect the ball screw and nut for any signs of wear or damage that could contribute to backlash.

• Adjust the preload on the ball screw if necessary to reduce backlash.

Spindle backless or runout can be checked using a dial indicator to measure the deviation in spindle rotation.

• Mount a dial indicator on the machine spindle

• Rotate the spindle and observe the dial indicator for any deviation

• Measure the runout at different points on the spindle to ensure accuracy

• Check for any loose components or worn out bearings that may cause runout

• Consult the machine manual for specific instructions on checking spindle runout

A micrometre is a unit of length equal to one millionth of a meter, commonly used in precision engineering and measurement.
