<p>A method of cutting panels with or stacks of panels a circular cutting saw to effect extremely neat and rapid cuts with no splintering. The saw cuts a panel in two steps, first by acting thereon through a portion of its thickness during a horizontal stroke, and then through the remaining portion of its thickness during the reverse stroke, while the direction of rotation of the saw remains unchanged and is such that the teeth thereof act successively on the two faces of the panel and press them inwardly of said panel. The saw is precisely adjustable both horizontally and vertically. Before being positioned for the first cutting step, it is displaced both vertically and horizontally to effect on the side of the panel where the cutting stroke is initiated and terminated one or more incisions compressing the panel material inwardly thereby, avoiding splintering during the subsequent cutting operations.</p> |
