The machine comprises two vertical columns (1), a horizontal support crossbeam (3) displaceable vertically in a Z vertical direction, in a guided manner in the two vertical columns (1), and at least one carriage (4) that holds a tool holder head (6), the support crossbeam (3) comprising a longitudinal guide (32) on which the carriage can slide in a Y direction. The carriage (4) comprises at least two hydrostatic cells (511, 512) configured to provide a film of hydrostatic fluid on the longitudinal guide (32), the hydrostatic cells (511, 512) being separated in the Y direction. The flow of hydrostatic fluid provided by at least one of the hydrostatic cells (511, 512) can be varied to cause an angular displacement of the carriage (4) with respect to the support crossbeam (3) in a ZY vertical plane. |
