PURPOSE:To minimize a pressure drop in a flow path further facilitate adjusting work of a static pressure balance, by forming a fluid throttle part in the main unit of a cutter spindle box so as to directly supply the fluid of prescribed pressure in the fluid throttle part to the fluid pocket part of a sleeve. CONSTITUTION:A fluid throttle part 14 is formed in the main unit 13 of a cutter spindle box, and fluid of prescribed pressure controlled by the fluid throttle part 14 is directly supplied to the fluid pocket part of a sleeve 12. In this way, a distance between the fluid throttle part 14 and the pocket part of the sleeve 12 is decreased, consequently a pressure drop in a flow path is minimized, while consequently any necessity for considering unevenness of the pressure drop in the flow path is eliminated, resulting in the easy adjustment of a static pressure balance. |
