Machine tool

A machine tool comprising:

• a base having a mounting space inside, in which a workpiece is mounted, wherein the base has shaft holes through a pair of opposing walls, and the base further has a pair of first-axial slides;
• a saddle coupled to the pair of first-axial slides of the base to slide in a first axis direction, the saddle having a pair of opposing second-axial slides, and a respective longitudinal axis of each of the second-axial slides extends parallel to a second axis direction that crosses the first axis direction;
• a crosspiece coupled to the pair of second-axial slides of the saddle to slide in the second axis direction and having a pair of opposing third-axial slides, and a respective longitudinal axis of each of the third-axial slides extends perpendicular to a plane, which is formed by the first axis direction and the second axis direction;
• a vertical ram coupled to the pair of third-axial slides of the crosspiece to slide in a third axis direction perpendicular to the plane formed by the first axis direction and the second axis direction, and the vertical ram holding a first tool mounted at an end thereof to machine the workpiece;
• and
• a table disposed in the mounting space of the base so as to be able to rotate relative to the base through the shaft holes of the base,
• wherein the base has formed in a bed thereof an opening for discharging machined chips or cooling water,
• wherein the pair of walls of the base include a first wall and a second wall that are disposed on opposite sides of the mounting space, and one of the pair of first axial-slides is disposed at an upper end of the first wall and the other of the pair of first axial-slides is disposed at an upper end of the second wall, and an intermediate wall extends in the second axis direction from the first wall to the second wall, and the mounting space is defined by the pair of walls and the intermediate wall, and
• wherein one or more drain holes for the cooling water are formed in the intermediate wall, and a top surface of the intermediate wall is sloped at an angle towards the one or more drain holes.
