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 33f and a tool cutting edge 31f upon moving at least one of a core metal punch 33 and a trimming tool 31A, gaps H1, H2 are formed between the core metal punch 33 and a workpiece W. Damper mechanisms 100A, 100B are arranged in the gaps H1, H2. The damper mechanisms 100A, 100B are arranged so as to abut on the workpiece W when trimming is performed by the core metal cutting edge 33f and the tool cutting edge 31f, and are constituted so as to elastically deform when a force acts in a direction in which the trimming tool 31A moves forward and backward.
