1. A device for machining a frame welded from profile pieces, the device comprising:
at least one machining head, said at least one machining head having a swiveling axis about which the at least one machining head is adapted to be swiveled, and said at least one machining head having a positioning shaft defining a length from a first end to an opposing second end of the positioning shaft and the positioning shaft further defining a positioning shaft axis that extends parallel to the length, said positioning shaft extending through an interior of the at least one machining head such that the positioning shaft axis is arranged at an angle to the swiveling axis, with said positioning shaft having a first end area disposed at the first end of the positioning shaft and with said positioning shaft having a second end area disposed at the second end of the positioning shaft, with the first end area of the positioning shaft extending from one side of the at least one machining head and the second end area of the positioning shaft extending from an opposite side of the at least one machining head; and
a plurality of machining tools arranged on the positioning shaft of the at least one machining head, with each one of said plurality of machining tools configured for being moved individually into machining position in respect of the frame upon selective positioning of the at least one machining head about the swiveling axis by a first actuator and selective rotation of the positioning shaft about the positioning shaft axis by a second actuator,
wherein the plurality of machining tools comprises two or more motor-driven tools located at the first end area of the positioning shaft and splayed radially outwardly from the positioning shaft such that each of the two or more motor-driven tools is radially spaced from the positioning shaft axis, a first of the two or more motor-driven tools is driven in rotation for machining of the frame by a first motor-powered drive located at the first end area, and a second of the two or more motor-driven tools is driven in rotation for machining of the frame by a second motor-powered drive located at the first end area,
wherein the plurality of machining tools further comprises two or more non-rotary tools located at the second end area of the positioning shaft and splayed radially outwardly from the positioning shaft such that each of the two or more non-rotary tools is radially spaced from the positioning shaft axis,
wherein each one of the plurality of machining tools defines a respective machining tool axis and wherein each corresponding machining tool axis of the plurality of machining tools is aligned perpendicular to the positioning shaft axis.
