The utility model provides a machining device which is used for removing weld reinforcement of a to-be-machined pipe section and comprises a cutting part and a driving part, the to-be-machined pipe section at the to-be-machined position is sleeved with the cutting part and the driving part, and the cutting part is connected with the driving part at the to-be-machined position. And the driving part is used for driving the cutting part to rotate in the circumferential direction of the to-be-machined pipe section at the to-be-machined position, so that the cutting part rotationally cuts off the weld reinforcement of the peripheral wall of the to-be-machined pipe section. By arranging the driving part, the cutting part can be driven to rotationally cut the weld reinforcement of the peripheral wall of the to-be-machined pipe section at the to-be-machined position, the situation that the outer wall of the to-be-machined pipe section deforms due to stress concentration in the local grinding process can be avoided, t
