Improving Heavy-Duty Turning for Oil/Gas Valves

Indexable coated-carbide insert tripled material removal rate for a shop machining valves for oil-and-gas drilling parts, and more than doubled tool life Extra beta test Fine-tuning pays off Unique seating scheme

Heavy turning of "gummy" metals usually forces machine shops into a triage dilemma: they have to choose to emphasize cycle time performance, or chip control, or tool life, but they will not get all three of these goals at once, or even two of the three. Cutting deeper improves chip control and speeds up the operation but raises the risk of rupturing the tool at any moment. Cutting shallower may prevent tool rupture, but it slows down the operation, requires more pass
