Patent ID: 7784161

Claim:
A device for machining a corner area of a frame welded together out of profiled pieces, comprising at least one machining tool that can be moved by means of a first tool carrier into an appropriate machining position at the corner area of the frame, which first tool carrier is guided along at least one linear axis (X or Y) extending parallel to a horizontal clamping plane of the frame, and which first tool carrier is guided along a linear axis (Z) perpendicular thereto, wherein a second tool carrier having at least one further machining tool configured for machining one of the profiled pieces is attached to the first tool carrier via an arm extending from the first tool carrier such that the second tool carrier is laterally spaced with respect to the first tool carrier, wherein the first tool carrier can move the second tool carrier, and wherein the second tool carrier can be moved via a drive along at least another horizontal linear axis (p) extending at an angle (α) of about 45 degrees relative to the at least one axis along which the first tool carrier is guided, which at least one axis (y or x) extends in a diagonal direction of the frame.
