The invention relates to a cutting machine, in particular to a high-efficient water pipe cutting machine for supplying and draining water. The invention aims to solve the technical problem so as to provide the high-efficient water pipe cutting machine for supplying and draining water, which is fast in cutting speed, and even in kerf. In order to solve the technical problem, the invention providesthe high-efficient water pipe cutting machine for supplying and draining water, which comprises a top plate, a drive mechanism, a rotary mechanism, a cutting mechanism, a fixing mechanism, a left-right moving mechanism, a clamping mechanism, a side plate and a bottom plate. The side plate is fixedly connected to the bottom plate along a vertical direction; a first through hole for a water supply pipe to penetrate through is formed in the side plate; the top plate is fixedly connected to the top part of the side plate along a horizontal direction; the drive mechanism is fixedly connected to thebottom part of the top plate; and the rotary mechanism is fixedly connected to the bottom part of the top plate and the bottom plate. According to the high-efficient water pipe cutting machine for supplying and draining water provided by the invention, water pipes can be neatly and sufficiently cut, so that an effect on accelerating the cutting speed is achieved.
