The invention relates to the technical field of building machinery, in particular to a novel cutting machine. The novel cutting machine comprises a handle (1), anti-skid threads (2), a base (3), a worktable (4), a dust collection groove (5), a cutting groove (6), a cutting wheel (7), a displacement sensor (8), a protective cover (9), magnets (10), a conveyor belt (11), a connecting shaft (12), a motor (13) and a master controller (14), wherein the worktable (4) is arranged at the upper end of the base (3); the motor (13) is arranged on one side of the worktable (4); the cutting wheel (7) is arranged at the upper end of the worktable (4); the protective cover (9) is arranged at the upper end of the cutting wheel (7) and hinged to the base (3); and the cutting wheel (7) is arranged on the protective cover (9) through the connecting shaft (12). According to the novel cutting machine, dust generated by cutting can be adsorbed by the magnets in the protective cover, and dust left behind can be collected through the dust collection groove, so that the safety of the cutting ambient environment is protected.
