发明名称 ASYMMETRIC PULLEY AND LUG CUTTING APPRATUS INCLUDING THE ASYMMETRIC PULLEY
摘要 Disclosed are an asymmetric pulley and a lug cutting apparatus including the same, which can secure excellent machinability and minimize cut residue by applying an asymmetric pulley having an asymmetric structure in a process of cutting a lug using a wire saw. The asymmetric pulley according to the present invention comprises: a first roller having a first thickness and a first diameter; a second roller placed apart from and parallel to the first roller, having a second thickness thinner than the first thickness and a second diameter smaller than or same as the first diameter; and a roller connecting part arranged between the first roller and the second roller, coupling the first roller and the second roller, and having a groove so that the wire saw is inserted inside the first roller and the second roller and performs horizontal reciprocating motion.
