Abstract

A machine tool capable of reducing the vibration of a spindle head to enable a high-precision machining, wherein a column (2) is mounted fixedly onto a bed (1), a first saddle (4) forming a square frame body of rectangular cross-section is mounted on the column (2) movably in vertical direction (f1), a second saddle (6) forming a square frame body (6a) smaller in size than the above square frame body is mounted inside the first saddle (4) movably in lateral direction (f2), a horizontal guide frame (6b) of a specified length is mounted on the rear surface of the square frame body (6a) of the second saddle (6) in the state of being crossed at right angle to the rear surface, rail members (5, 7) are laid down on square frame body upper and lower prismatic bodies (4b, 4c) of the first saddle (4) and the horizontal guide frame (6b) of the second saddle (6), and concrete is filled sealingly into the square frame body of the first saddle (4) and/or the square frame body of the second saddle (6) and the horizontal guide frame (6b) so as to form a vibration damping structural body.
