ABSTRACT:
A spindle device for supplying air for cleaning and a coolant for cooling or lubricating, including: a tool holder (11) with a coolant passage (22) through which a coolant is supplied; a spindle (10) having a support surface (26) formed at the front portion thereof for accepting the tool holder (11); a drawing bolt (25) having a through-hole for supplying air or a coolant and movably arranged in the spindle (11) for clamping or unclamping the tool holder (11) accepted on the support portion (26) of the spindle (11); and a pull stud (12) attached on the tool holder (11) and provided with a valve (13), the valve (13) being located in association with the coolant passage (22) and the through-hole, the valve (13) being so constructed as to open or close according to the movement of the drawing bolt (25) in such a manner that the valve (13) opens so as to connect the through-hole to the coolant passage (22) when the tool holder (11) is clamped, whereas the valve (13) temporarily closes so as to shut the connection between the through-hole and the coolant passage (22) when the tool holder (11) is unclamped, wherein a coolant can be supplied from the through-hole to the coolant passage (22) via the valve (13) when the tool holder (11) is clamped, whereas air can be supplied from the through-hole by bypassing the coolant passage (22) when the tool holder (11) is unclamped.
