Adjusting Backlash - Grizzly G0731 Owner's Manual

Adjusting Backlash

Leadscrew backlash is the amount of motion the
leadscrew rotates before the device begins to
move. Leadscrews always have a certain amount
of backlash which increases with wear. Generally,
0.005"–0.010" of backlash is an acceptable range.
The backlash of the longitudinal and cross
leadscrew is adjusted by changing the gap in the
leadscrew nuts (see Figures 53–54).
