The vibration magnitude of the smtcl machine tool spindle relative to the worktable (or tool holder) directly affects the surface roughness and geometric accuracy of the machined parts, and is one of the main dynamic performance indicators of the machine tool.
Measure the vibration (amplitude) of the machine tool spindle relative to the worktable (or tool holder) during forward and reverse operation at various speeds, and perform frequency spectrum analysis of the relative vibration at the maximum amplitude motion state.
