Processing method of MPP power cable protection pipe

The invention discloses a machining method of an MPP power cable protection pipe. The machining method comprises the following steps that S1, the MPP power cable protection pipe penetrates through a fixing clamp and a feeding block which are arranged on a machine body; s2, the MPP power cable protection pipe is controlled to move leftwards along with the feeding block, and the left end of the MPP power cable protection pipe abuts against a left grinding plate; s3, a swing rod is controlled to swing downwards under the action of the gravity of the swing rod, a cutting piece is driven to descend, and the MPP power cable protection pipe is cut; s4, a swing rod is controlled to swing upwards, then a pipe frame is driven to rotate clockwise by 90 degrees, the pipe frame drives the cutting pipe opening of the MPP power cable protection pipe to rub with a left grinding plate and a right grinding plate, and then burrs are removed; s5, when the pipe frame drives the MPP power cable protection pipe to rotate to a disch
