Metallic piece drilling machine for turbo-alternator set in e.g. nuclear electricity production center, has control unit digitally controlling head, and displacing shaft arranged parallel to plane and displacing head parallel to plane

摘要

The machine (40) has a digital control unit (43) digitally controlling a drilling head (42), and a removable fixation base provided with fixation terminals (11-13) to removably fix the machine on a metallic piece to be drilled and defining a drilling plane (1). A displacing shaft (31) is arranged parallel to the plane defined by the base and displaces the head parallel to the plane. The displacement shaft is extended between the terminals. Each terminal has rotational axles (22) that are arranged perpendicular to the displacement shaft.
