Abstract:
A machine (1) for cutting panels (2) and including pressure clamping devices (25) for clamping the panels, the machine (1) further including a frame (3) having a substantially horizontal worktable (4), and guides (5) extending to the sides of the frame (3) in a given substantially horizontal direction (6); and a carriage (7) fitted in freely-sliding manner to said guides (5) so as to move, in relation to said frame (3), to and from an idle position wherein said carriage (7) is located laterally in relation to said worktable (4); the machine (1) being characterized in that said carriage (7) houses first supporting and fast-fit connecting means (30, 31) having a respective longitudinal first axis (32, 33) perpendicular to said direction (6); said first supporting and fast-fit connecting means (30, 31) engaging and supporting at least one cutting tool (29) including a second fast-fit connecting means (21) and a saw (16, 18) for cutting said panels (2) in said direction (6);wherein said first supporting and fast-fit connecting means (30, 31) comprises a first bush (62) and a second flexible bush (63) coaxial with said first bush (62); said first bush (62) and said second flexible bush (63) arranged and positioned for expanding said second flexible bush (63) by axial displacement of said first bush (62), thereby causing an outer surface of a conical portion (21) of a toolholder body (12, 14) of said cutting tool to be pushed against an inner surface of a conical portion (43) of a cavity (41) formed in said first supporting and fast-fit connecting means (30, 31), said expansion furthermore causing a pressing action of toolholder body (12, 14) on a surface (69) integral with said first supporting and fast-fit connecting means (30, 31).
