The demanding aircraft industry constantly challenges aerospace manufacturers to look for ways to improve processes, reduce downtime and ultimately increase productivity. Inherent in engine component designs is a high degree of quality and tight tolerances. The work materials – heat resistant super alloys (HRSAs) – have poor machinability, adding to the difficulty in machining these parts. As a cutting tool manufacturer, NTK develops innovative high-quality products to ensure there is no effect on the integrity or surface finish of the part while enabling higher productivity. Blisk engine components, where the hub and blades are machined from a solid piece of HRSA material (Inconel 718) are complex machining applications requiring tools that are efficient, reliable, and produce parts that meet stringent manufacturing specifications. Now imagine machining these parts at cutting speeds normally reserved for aluminum. This is a reality with our durable solid ceramic end mill, made of SX9 grade SiAlON, which typically runs at speeds of 2,000sfm to 3,000sfm (with a minimal speed of 1,000sfm). The intricate flute edge design withstands the extreme heat and pressure generated when mach...
