<p>A drilling machine comprising a loading channel (1) defining a working plane (XY) and a feeding and loading direction (X) of a panel (P) to be processed, a drilling unit (5) being arranged for operation in correspondence and below with respect to the working plane (XY), the drilling unit (5) comprising a tool-bearing head (9) adapted to be moved at least along a transversal direction (Y) perpendicular to the loading direction (X) on the working plane, and along a working axis (Z) orthogonal with the working plane (XY). The drilling unit comprises a ring-shaped carriage (8) slidably supported along the transversal direction (Y) and having a central hole (8a) inside which the tool-bearing head (9) is housed and is slidably supported according to the working axis (Z) by the carriage itself.</p> |
