Abstract
A main spindle unit includes: a damper bearing that restricts vibrations of a main spindle by being supplied with a fluid; a fluid supply device that supplies the fluid to the damper bearing, and that is able to adjust a flow rate of the fluid; a vibration detection sensor that detects a vibration of the main spindle; and a controller that adjusts the flow rate of the fluid supplied from the fluid supply device, based on the magnitude of the vibration detected by the vibration detection sensor.
