Lathe machining is part of mechanical machining, and mainly comprises two machining modes: one is to fix a turning tool and process a workpiece which is not formed in rotation; the other method is to fix the workpiece and perform precision machining by the high-speed rotation of the workpiece and the transverse and longitudinal movement of the turning tool. In a common lathe, a tool rest for placing a tool is fixed on a carriage, and machining of a workpiece is achieved by sliding the carriage, wherein a lathe backer is used for limiting the stroke of the carriage so as to control the feed amount of the tool. The existing lathe backer is generally plugged in from the tail of the equipment by a cylindrical long rod backer, penetrates through a spindle box of the equipment, fastens a positioning backer at the tail of the equipment, and suspends the front end in a hole of a chuck. In order to improve the wear resistance of the lathe backer and facilitate the discharge of the waste chips during lathe machining, the existing lathe backer is often provided with a stopper, and the purpose is mainly to improve the wear resistance of the lathe backer and discharge the waste chips through a chip discharge cavity inside the stopper.
