Abstract
A drilling machine (10) for making an excavation in ground (S) in a vertical drilling direction (F). The drilling machine (10) includes: a support (12) having a longitudinal direction (L); a drilling module (14) provided with cutter members (16), the drilling module being movable in translation relative to the support; and a movement device arranged between the support and the drilling module in order to move the drilling module (14) relative to the support along the longitudinal direction of the support. The machine is characterized by the fact that the movement device includes a damper (70) for damping the vibration generated by the drilling module while drilling.
