The Forming machines are used for the forging process. These ma-chines can produce mass qua-ntities of sockets and parts with high accuracy that ordinary drop forging machines can not achieve. However, for small production runs, ordinary forging machines are also used.The forged steel is turned into required shapes and dimensions. The MC (Machining Center) oper-ates with extraordinary speed and precision. The article number, size, logo, production number, and MA-DE IN JAPAN are marked on the products after the turning process has been completed.■ FORGING PROCESS■ TURNING & MARKING PROCESSMaking of Ko-ken products004
