Maximum value of motion error at four different speeds.
| | Rotating speed (r/min) | Maximum displacement in the x-direction (μm) | Maximum displacement in the y-direction (μm) | Maximum value of the spindle inclination angle θ (μrad) | Maximum displacement in the z-direction (μm) |
| | 300 | 3.71 | 3.78 | 3.00 | 2.50 | | 600 | 3.92 | 3.99 | 3.84 | 3.01 | | 900 | 4.06 | 4.13 | 4.22 | 3.37 | | 1200 | 4.13 | 4.20 | 4.60 | 3.75 | | Increase ratio | 10.2% | 10% | 34.8% | 33% |
