    • 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.
    • 旨在提供一种具有柱塞的机械加工工具,该冲头具有简单的结构和便宜的装置成本,并且能够校正由于延长冲头而引起的主轴单元的尖端的偏转。 一种用于加工工具中的冲头1的偏转校正装置,其具有沿柱14的引导件垂直移动的鞍座13和容纳主轴单元15的冲头1并且沿水平方向可滑动地嵌合在鞍座13中 。 该装置可以包括多个静压轴承2a,其中鞍座13沿着柱14的纵向方向被柱14支撑,并且控制单元10根据垂直方向控制静压轴承2a的液压 使压头1的位移保持在冲头1的主轴的方向上的平直度,从而通过控制液压而引起主轴单元15的倾斜偏移。
