The External Turning Tool Holder performs the roughing and finishing operations on the brake disc's outer diameter, friction surface, and mounting face. Equipped with precision indexable inserts, it removes excess material efficiently while maintaining stable cutting forces. This process ensures accurate dimensions, flatness, and concentricity, providing a reliable foundation for subsequent drilling and chamfering operations.
The External Turning Tool Holder performs roughing and finishing of the brake disc's outer diameter and friction surfaces, ensuring precise dimensions, excellent surface finish, and stable machining for subsequent operations.
