A machining center, comprising: a number N of workpiece tables equal to or greater than three, a number N of first guides, which extend parallel to a first direction; along said first guides being movable respective to workpiece tables, one for each first guide, a number N1 of second guides, which extend parallel to a second direction transverse to said first direction, a number N1 of machining groups each comprising at least one machining head; each machining group being movable parallel to said second direction along a respective second guide; a number N(N1) of machining areas wherein the machining groups can operate on workpieces present on said tables; along each first guide, or for a respective table, there being present N1 machining areas, one for each machining group, so that each machining group can operate, according to a programmed work cycle, on all said N workpiece tables, a number N of workpiece loading/unloading areas, one for each workpiece table.

A machining center includes a number N of workpiece tables. A number N of first guides extend parallel to a first direction. Along the first guides is movable respective to workpiece tables, one for each first guide. A number N1 of second guides extend parallel to a second direction transverse to the first direction. A number N1 of machining groups each include at least one machining head. Each machining group is movable parallel to the second direction along a respective second guide. A number N(N1) of machining areas is provided. The machining groups can operate on workpieces present on the tables. Along each first guide, or for a respective table, there is present N1 machining areas, one for each machining group, so that each machining group can operate, according to a programmed work cycle, on all the N workpiece tables.

Processing machine and related operating method, wherein the processing machine is a machine for machining components having a body within which there are a chamber and a movement bridge which is movable on the upper part of the chamber, wherein the processing machine includes a positioning device integrated in the structure of the bridge and equipped with grabbing devices for the grabbing of the element to be machined and for the transportation of the element to be machined towards and from a machining bench of the machine.
