Sandvik Coromant has developed new CB7105 and CB7115 grades for transmission and hard part turning. The grades can achieve efficient and secure machining with an improved surface finish.
Hard part turning is usually a finishing or semi-finishing process with high dimensional accuracy and surface quality requirements. Component materials are case hardened steel or induction hardened steel. Typical machining challenges with these materials are surface and dimensional tolerance demand with competitive tool life.
According to the company, CB7105 offers lower cost per part through high speed machining or longer tool life at lower speed, while CB7115 offers lower cost per part when aiming for one cut strategy at high speed.
