A table cutting machine, comprising: a table for placing a material to be cut; and a main body of the cutting machine arranged such that the main body can be operated to move vertically above the table; wherein the main body of the cutting machine comprises a cutting blade; wherein the main body of the cutting machine is supported on a rear part of the table through a plurality of slide mechanisms (20, 40) such that the main body of the cutting machine can be slidable in the backward and forward direction along the direction of the surface of the table; wherein each of the slide mechanism (20, 40) includes a slide guiding member (22, 42) extending in the backward and forward direction and a slide supporting member (21, 41) supporting the slide guiding member (22, 42); wherein there are arranged a slide mechanism of the plurality of the slide mechanisms which is of pattern 1 in which the slide guiding member moves in the backward and forward direction when the main body of the cutting machine is slid in the backward and forward direction while the slide supporting member is fixed, and a slide mechanism of the plurality of slide mechanisms which is of pattern 2 in which the slide supporting member moves in the backward and forward direction when the main body of the cutting machine is slid in the backward and forward direction while the slide guiding member is fixed with respect to the slide operation of the main body of the cutting machine; wherein an upper stage slide mechanism and a lower stage slide mechanism are arranged in the vertical direction as the plurality of the slide mechanisms (20, 40); and wherein the length of the upper stage slide mechanism is set so that a front end part of the upper stage slide mechanism cannot project in the forward direction from a rotational center of the cutting blade. a table for placing a material to be cut; and a main body of the cutting machine arranged such that the main body can be operated to move vertically above the table; wherein the main body of the cutting machine comprises a cutting blade; wherein the main body of the cutting machine is supported on a rear part of the table through a plurality of slide mechanisms (20, 40) such that the main body of the cutting machine can be slidable in the backward and forward direction along the direction of the surface of the table; wherein each of the slide mechanism (20, 40) includes a slide guiding member (22, 42) extending in the backward and forward direction and a slide supporting member (21, 41) supporting the slide guiding member (22, 42); wherein there are arranged a slide mechanism of the plurality of the slide mechanisms which is of pattern 1 in which the slide guiding member moves in the backward and forward direction when the main body of the cutting machine is slid in the backward and forward direction while the slide supporting member is fixed, and a slide mechanism of the plurality of slide mechanisms which is of pattern 2 in which the slide supporting member moves in the backward and forward direction when the main body of the cutting machine is slid in the backward and forward direction while the slide guiding member is fixed with respect to the slide operation of the main body of the cutting machine; wherein an upper stage slide mechanism and a lower stage slide mechanism are arranged in the vertical direction as the plurality of the slide mechanisms (20, 40); and wherein the length of the upper stage slide mechanism is set so that a front end part of the upper stage slide mechanism cannot project in the forward direction from a rotational center of the cutting blade.
