Figure 3
The illustration contains two main sections. The upper section shows a tube laser cutting machine. The tube processing machine is positioned horizontally and consists of a long rectangular base structure with a rail-like platform extending from left to right. At the far left end of the machine, a box-shaped housing contains a circular chuck holding a cylindrical tube aligned along the machine bed. The tube extends toward the center of the machine and rests on several small cylindrical rollers positioned along the platform. Near the center of the machine stands a vertical support column holding a rectangular control unit with a dark display screen facing forward. Behind the control unit, several curved cable conduits connect to a rectangular enclosure mounted toward the right side of the machine. Below the central processing area is a large open rectangular collection tray attached to the base of the machine. A circular magnified callout appears on the right side of the illustration and is connected by lines to the central working area. Inside the magnified circle, a close-up view shows a cutting head positioned above a rectangular tube. The cutting head includes a processing nozzle directed toward the surface of the tube, while a circular rotating chuck supports the tube. The close-up highlights the location where the tool interacts with the tube surface during the machining process. The lower section is divided into three vertical panels separated by two vertical lines. In the left panel, several individual sheet metal components are shown. At the top appears a rectangular hollow box-like piece. Below it are two flat rectangular plates with holes and notched edges. At the bottom, the parts are shown assembled into a structure consisting of a rectangular base with two upright plates attached. In the middle panel, a long rectangular metal profile is shown with a V-shaped central bend along its length. Below it, the same profile is shown bent into a right-angle corner shape. The right panel shows final tube joint pieces. The upper piece is a straight rectangular tube with a circular cutout in the center. A circular magnified inset highlights the internal profile of the cut, showing an interlocking tube joint shape inside the opening. Below it is another bent rectangular tube forming a right-angle corner with a curved notch at the inner corner of the bend.Tube laser cutting machine and examples of cutting alternatives.
