MACHINE TOOL AND METHOD FOR ADJUSTING INCLINATION OF WORK-PIECE MOUNTING BASE

To adjust an inclination of a work-piece easily and promptly.SOLUTION: A machine tool (100) comprises: a base (1); a work-piece mounting base (6) provided above the base (1); clampers (8) that press the work-piece mounting base (6) against the base (1); a plurality of jacks (7), provided in at least three places between the work-piece mounting base (6) and the base (1), which jack up the work-piece base (6) with respect to the base (1) against pressing force of the clampers (8); and a control device that controls rising amounts of the plurality of jacks (7) so that an inclination of a reference surface of the work-piece is adjusted to a target inclination, on the basis of the target inclination of the reference surface of the work-piece and an actual inclination of the reference surface of the work-piece mounted on the work-piece mounting base (6).SELECTED DRAWING: Figure 2 【課題】容易に且つ迅速にワークの傾きを調整すること。【解決手段】工作機械（１００）は、基台（１）と、基台（１）の上方に設けられたワーク取付台（６）と、ワーク取付台（６）を基台（１）に向けて押し付けるクランパ（８）と、ワーク取付台（６）と基台（１）との間の少なくとも３箇所に設けられ、クランパ（８）の押し付け力に抗して基台（１）に対してワーク取付台（６）を持ち上げる、複数のジャッキ（７）と、ワークの基準面の目標傾きと、ワーク取付台（６）に取り付けられたワークの基準面の実際の傾きと、に基づいて、ワークの基準面の傾きを目標傾きに調整するように、複数のジャッキ（７）の上昇量を制御する制御装置と、を具備する。【選択図】図２
