Machine tool that comprises a vertical column (1) displaceable in a horizontal direction according to a first (X) horizontal axis, with respect to a support (2) anchored to the ground, a horizontal beam (3) mounted on said column (1) and displaceable vertically according to a (Y) vertical axis, a tool holder head (4) mounted on said horizontal beam (3) and displaceable with respect to said horizontal beam (3) according to a second (Z) horizontal axis perpendicular to said first (X) horizontal axis, and counterbalancing means (5) of the position of the head that comprise at least one cable (6, 7) connected to the horizontal beam (3). The counterbalancing means (5) are mounted in a displaceable manner on outer guiding means (8') such that the counterbalancing means (5) can displace according to a direction substantially parallel to the first (x) horizontal axis. |
