The invention concerns a procedure for the production of window parts, or parts for equivalent building elements. In the procedure, the element parts are planed at least partially to its final sectional shape, and the parts are then cut to the required element length. The parts are arranged to be fed forward in their longitudinal direction, and their ends are prepared as corner joints using a cutting tool with a horizontal spindle and vertical feed movement, without alter-ing the parts' forward feed position. Several parts can be laid side by side and processed simultaneously. The fine-planing process will then bring the parts to their final sectional form. <IMAGE>
