The utility model provides a fervent cutting mill of pipeline, including the cutting torch, still include cutting torch strutting arrangement, pipeline strutting arrangement and transmission, whereinthe cutting torch sets up on the cutting torch strutting arrangement, the antifriction bearing that pipe supporting device set up including the symmetry, during the cutting, the cutting torch with cutting torch strutting arrangement fixed connection, the gear drive pipeline is in the last rotation of pipe supporting device, cutting torch pipeline cutting. The utility model discloses a fervent cutting mill of pipeline, fixed with traditional pipeline, the form that the cutting torch moved is changed into the pipeline and is rotated, and the fixed form of cutting torch guarantees through the symmetrical antifriction bearing who sets up that the pipeline rotates smooth -going stability simultaneously, can stop effectively to guarantee cutting accuracy because the cutting torch that the steelpipe deviation from circular form leads to squints.
