Chattering suppression apparatus (10) comprises multiple bolt members (24a through 24d) for mounting boring bar (20) in the spindle (18). Inside the main body configuring bolt members (24a through 24d), a damper chamber (34) is formed and, inside the damper chamber (34), a friction damper section (36) that suppresses the vibration energy that can cause chatters during machining operation of workpiece W, through sliding friction, is housed in the movable state. |
