Check procedure:
Rotating torque: 0.023 N.m {0.23 kgf.cm} or less
Use a torque gage to take measurements. Or, wind a string around the periphery of the rotary block as
illustrated below and, holding the Z-slider shaft in position, measure the torque when the rotary block starts
turning with a tension gage.
When a tension gage is used: 1.96 N {200 gf) or less

Being greatly concerned with the θ-axis rotating torque, it affects θ settling time (damping characteristics).
A possible cause of the trouble includes want of silicone grease applied to the oil seal in the rotary block
assembly.
Degraded placement accuracy (variations in θ)
