                  Machining

                  The purpose of carbon graphite material machining is to rely on cutting to achieve the required size, shape, accuracy, etc., to make electrode bodies and joints that meet the requirements of use.

                  Graphite electrode processing is divided into two independent processes of electrode body and joint.

                  The main body processing includes 3 processes: boring and rough flat end, outer and flat end, and thread milling. The processing of the conical joint can be divided into 6 processes: cutting, flat end, turning cone, milling thread, drilling bolt And slotted.
