Abstract
A circular sawing machine comprises a base table, a main support link having one end swingably pivoted to the base table about a first pivotal point, a support arm pivoted to the main support link to be swingable about a second pivotal point formed to the other end of the main support link, a circular saw blade mounted to the support arm to be rotatable through a rotational shaft, and a swing motion limiting link disposed between a third pivotal point formed to the base table and a fourth pivotal point formed to the support arm. The fourth pivotal point is positioned on a line connecting the second pivotal point and the rotational shaft, and a distance between the first pivotal point and the second pivotal point, a distance between the third pivotal point and the fourth pivotal point and a distance between the second pivotal point and the rotational shaft are set substantially equal to each other. A distance between the first pivotal point and the third pivotal point is set to about two times a distance between the second pivotal point and the fourth pivotal point. A support frame member is provided for the base table to be detachable to support a workpiece. A turn table is mounted…
