PURPOSE: A spindle assembly having the cooling structure is provided to maximize cooling efficiency by repetitively flowing the cooling oil along a cooling oil channel of a zigzag shape to the longitudinal direction of spindles. CONSTITUTION: A spindle assembly comprises a spindle and a main housing (140). One or more cooling oil channels (150) are extended in a zigzag shape to the longitudinal direction of spindles inside a member forming the main housing. An inlet unit and an outlet unit of the cooling oil channels are each connected to a supply unit and a collecting unit of an outer cooling oil supply device. |
