Claims

[Scope of utility model registration request]

A tool holder attachment/detachment mechanism for attaching and detaching a pull stud provided on the tool holder, a drawbar for operating this tool holder attachment/detachment mechanism to fix or detach the tool holder from the spindle taper hole, and a drawbar that penetrates inside the drawbar and the tool holder. A coolant circuit provided in the coolant circuit, a valve mechanism provided in the coolant circuit that normally closes the coolant circuit and can be opened by fluid having a pressure equal to or higher than a predetermined pressure supplied to the coolant circuit, and the valve. An air circuit that is branched from the coolant circuit on the upstream side of the coolant supply from the mechanism and communicated with the main shaft taper hole through the gap between the outer periphery of the drawbar and the inner periphery of the main shaft, and an air circuit provided in the middle of this air circuit. A spindle tapered hole cleaning device characterized by comprising: an on-off valve mechanism that closes an air circuit when a tool holder is fixed in a tool holder attaching/detaching mechanism using a drawbar, and opens the air circuit when the tool holder is detached.
