Abstract

The present invention relates to a machining center, and more particularly, to a machining center which allows a bed and a column to be integrated, thereby being capable of reducing the overall size of the apparatus and saving production costs and allows vibrations and displacements occurring in each of 5 axes to be rapidly transmitted to other axes to minimize relative vibrations and displacements between the axes, thereby being capable of performing high-precision machining.

First claim

The invention claimed is:

1. A 5-axis machining center comprising:
a base that has the shape of a pentagonal pillar including a first lateral surface, a second lateral surface, a third lateral surface, a fourth lateral surface, and a fifth lateral surface, and that is erected on the ground in a Y-axis direction;
a saddle attached to the first lateral surface of the base to be movable in the Y-axis direction;
a Z-axis ram coupled to the saddle to be movable in a Z-axis direction;
a spindle coupled to a front end of the Z-axis ram horizontally with the Z-axis ram, capable of mounting a tool and rotating a mounted tool, the spindle moving along with the tool in the Y-axis direction and the Z-axis direction outside the base; and
an X-axis ram attached to the second lateral surface orthogonal to the first lateral surface of the base to be movable in an X-axis direction;
a table coupled to a front end of the X-axis ram horizontally with X-axis ram and capable of mounting a workpiece, the table moving along with the workpiece in the X-axis direction outside the base,
wherein a triangle (t) occurs at the intersection of a horizontal line (h) passing on the third lateral surface between the first lateral surface and the second lateral surface, an X axis, and a Z axis such that a space in which the workpiece is machined is formed in front of the third lateral surface, the table includes a table body rotatable around an a axis parallel to the X axis, and a table surface rotatable on the table body around a b axis perpendicular to the a axis and allowing the workpiece to be mounted thereon, and other structures are not formed below the table to allow chips generated when the workpiece is machined to free fall to the ground.
