How do you stop a machine from chattering and fix a misaligned shaft?

Discover Curing Machine Chatter and Shaft MisalignmentA grinding machine leaves spiral marks on the part and screams with high-pitched chatter while the pump next to it runs hot with a 1× and 2× vibration signature. The spiral spacing tells you the exact speed of the shaking part. The 1× spike means the rotor is unbalanced; the 2× spike means the shafts are misaligned so the coupling bends twice per revolution. Chatter itself is different: the tool cuts a wave, then hits that same wave on the next pass and feeds energy back…
