Abstract
To provide a trimming device with which it is possible to suppress the deterioration of shape quality after trimming a cylindrical workpiece. When trimming is performed by means of a core metal cutting edge () and a tool cutting edge () upon moving at least one of a core metal punch () and a trimming tool (A), gaps (H, H) are formed between the core metal punch () and a workpiece (W). Damper mechanisms (A,B) are arranged in the gaps (H, H). The damper mechanisms (A,B) are arranged so as to abut on the workpiece (W) when trimming is performed by the core metal cutting edge () and the tool cutting edge (), and are constituted so as to elastically deform when a force acts in a direction in which the trimming tool (A) moves forward and backward.
