Abstract

It is intended to provide a machining tool provided with a ram, which has a simple structure and an inexpensive device cost, and is capable of correcting a deflection of a tip of a main shaft unit caused by extending the ram. A deflection correction device for a ram 1 in a machining tool which is provided with a saddle 13 moving vertically along a guide of a column 14 and the ram 1 housing a main shaft unit 15 and being fitted in the saddle 13 slidably in a horizontal direction. The device may include a plurality of hydrostatic bearings 2a via which the saddle 13 is supported by the column 14 in a longitudinal direction of the column 14, and a control unit 10 which controls a hydraulic pressure of the hydrostatic bearing 2a in accordance with a vertical displacement of the ram 1 to maintain a straightness of the ram 1 in a direction of a main shaft of the ram 1 so as to correct a misalignment of the main shaft unit 15 by an inclination of the saddle 13 caused by controlling the hydraulic pressure.
