Piston ring machining
WSS CBN turning and grooving tools enable efficient machining of iron ring grooved pistons. Compared to carbide inserts, CBN has a longer machining life and better machining quality. Ferrous grooves are made of martensitic or austenitic cast iron, which is very hard and strong, with a high specific capacity and low impact toughness. This is why CBN is the ideal material for finishing iron ring grooves.
