Herein, you will learn about the pressing procedure used in the manufacturing process of carbide inserts. The raw materials for inserts, which are mostly composed of cobalt and tungsten carbide in different combinations, are initially as a powder. This mixture is fed through a fully automated, CNC-controlled press that has dies and punches to enable it to be pressed into the required basic shape and size until it achieves moderate strength. The operator controls this procedure visually. Take note that the insert breaks quickly at this stage and is quite fragile.
