1. A machining center, comprising:
three workpiece tables;
three first guides, which extend parallel to a first direction, each of said three workpiece tables being movable, separately from said other two of said three workpiece tables, along a respective one of said first guides,
two second guides, which extend parallel to a second direction orthogonal to said first direction;
two machining groups each comprising at least one machining head, each machining group being movable parallel to said second direction along a respective one of said second guides;
six machining areas in which said two machining groups can machine a workpiece or workpieces present on said three workpiece tables, along each first guide there being present two machining areas, one for each machining group, so that each machining group can operate, according to a programmed work cycle, on all of said three workpiece tables;
three workpiece loading/unloading areas, one for each workpiece table; and
a stationary portal structure comprising a front side and a rear side, said stationary portal structure being arranged orthogonally to said three first guides and being stationary relative to said three first guides and being stationary relative to said two second guides;
wherein said three workpiece loading/unloading areas are provided in first end areas of said three first guides and, in a state wherein one of the three workpiece tables is on the corresponding loading/unloading area, said one of the three workpiece tables is completely located on a space delimited from said rear side of the stationary portal structure towards said first end areas.
