Study on vibration characteristics of rolling mill based

The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, thebination of opening parameters was obtained.

Spindle Vibration Tolerances Mill

Displacement Tolerance: Not to exceed 0.100 MIL at max speed. Note: For 15K spindles, at 8K and 15K CPM the spike must not be more than 0.100 MIL. Note: For GR machines, the spike at the maximum spindle speed must not be more than 0.200 MIL. Velocity Tolerances: Not to exceed a total of 3 spikes between 30k and 210k cpm that exceed 0.005 in/s.
