Excess material machining treatment device for lathe machining

The invention discloses an excess material machining treatment device for lathe machining. The excess material machining treatment device comprises a work table and is characterized in that a machining box is fixedly installed at the top of the work table, the top of the machining box is of an opening structure, a feeding hopper is fixedly connected to the periphery of the top of the machining box, and limiting sliding holes are formed in the left side and the right side of the machining box correspondingly; and limiting sliding blocks are slidably installed on the inner walls of the two limiting sliding holes correspondingly, a same sliding plate is fixedly installed on the sides, close to each other, of the two limiting sliding blocks, and the outer walls of the periphery of the sliding plate make sliding contact with the inner wall of the machining box. Excess materials on the sliding plate can be extruded and broken through downward movement of a pressing plate and pressing teeth, after the excess materia
