AddMultiTurn – Bearing – T9215

IMPROVED TOOL LIFE AND COST

ISO inserts were being used, but issues such as burrs and ring-shaped chips wrapping around the workpiece occurred. Additionally, there was a request to improve the short tool life.

By applying the AddMultiTurn, Tungaloy changed the external turning process from front turning to back turning with a single pass. This change suppressed burr formation and resolved the problem of chip entanglement. As a result, AddMultiTurn achieved a 1.15x increase in machining efficiency, consolidation of ISO inserts from two types to one, and a 1.4x extension in tool life.
