Cylinder barrel machining device and machining method

The invention provides a cylinder barrel machining device and method, and relates to the technical field of cylinder barrel machining. The cylinder barrel machining device comprises a chamfering mechanism, a machining mechanism and a cutter. The chamfering mechanism comprises a chamfering assembly, and the chamfering assembly is used for chamfering the two ends of the cylinder barrel; the machining mechanism comprises two tip cones, positioning conical grooves are formed in the two tip cones, openings of the two positioning conical grooves are oppositely formed, and the chamfered cylinder barrel is positioned between the two positioning conical grooves; and the cutter and the center of the positioning conical groove are arranged at the same height so as to cut the positioned cylinder barrel. According to the cylinder barrel machining device and method, the structure is simple, operation is convenient, the positioning effect is good, and the use effect of the machined cylinder barrel is guaranteed. 本发明提供了一种缸筒加
