The shell and tube heat exchangers require thousands of holes in the sheets and baffles. Each hole must be chamfered, which requires accurate identification of the position of the previously drilled hole. We offer gantry machine with 2 milling – chamfering - drilling vertical units. Each of the vertical units has a 3D laser scanner that is integrated with the NC system of the machine tool. This allows us to make each hole with an accuracy of +/- 0.1mm (in each plane). After scanning the detail, a machining program is generated automatically (the operator’s task is limited to clamping the work piece and determining the base point).
