Provided is a cam type press capable of controlling deformation of a flange of a panel in the course of processing the flange, thus reducing deformation such as a crease, or the like, of the flange. The cam type press includes a padding cam installed to be movable in a slope direction. A slider is installed to be movable toward the padding cam, with a process gap into which a portion of a panel is inserted to form a flange between one side of the padding cam and one side of the slider. An adjustment block adjusts the process gap provided between the other side of the padding cam and the other side of the slider.
