Abstract
A numerically controlled machine tool that can accurately control a position of a machining member for machining a workpiece. The numerically controlled machine tool comprises: a first post member installed on a main body slidingly in a left/right direction; and first, second and third horizontal rails installed on the main body lengthily in the left/right direction and respectively coupled to two points of the rear surface and one point of the front surface of the first post member for guiding sliding of the first post member.

A numerically controlled machine tool, comprising:
- a body including a first longitudinal support having a longitudinal axis and an opposing second longitudinal support disposed parallel to the longitudinal axis;
- a first post member disposed on the body between the first longitudinal support and the opposing second opposing longitudinal support;
- a first driving part including a first driving motor connected to a first driving screw configured to translate the first post member in a first longitudinal direction along the longitudinal axis between the first longitudinal support and the opposing second longitudinal support, the first driving screw having a rotational axis disposed parallel to the longitudinal axis;
- a first horizontal rail disposed on a top portion of the opposing second longitudinal support;
- a second horizontal rail disposed on a vertically extending surface of the opposing second longitudinal support;
- and
- a third horizontal rail disposed on a top portion of the first longitudinal support,
- wherein the rotational axis of the first driving screw is disposed equidistant between a first horizontal rail driving center of the first horizontal rail and a second horizontal rail driving center of the second horizontal rail,
- wherein a third horizontal rail driving center of the third horizontal rail is disposed equidistant between the first horizontal rail driving center and the second horizontal rail driving center, and the third horizontal rail driving center is also disposed on a line perpendicularly extending from the rotational axis of the first driving screw, and
- wherein the first post member has a first side and an opposing second side, and the first post member is coupled to the first and second horizontal rails on the first side thereof, and is further coupled to the third horizontal rail on the opposing second side thereof.
