Jig component, terminal, shell, and method of manufacturing shell

The invention discloses a jig component, a terminal, a shell and a method for manufacturing the shell. The shell is provided with a gap comprising a straight line section and a curved line section, the straight line section extends in a straight line direction, and at least part of the curved line section extends along a curved line; the jig component is suitable for processing the gap and comprises a first cutter suitable for processing the straight line section, and a second cutter suitable for processing the curved line section. According to the jig component for the shell, the first cutter is used for processing the straight line section of the gap, and the second cutter is used for processing the curved line section of the gap, so that not only can abrasion of the cutters be reduced and the service lives of the cutters be prolonged, but also the quality of the shell is improved, and the defective rate of processing the shell is reduced, thereby shortening the production cycle and reducing the production cost.
