Steam turbines, also known as steam turbine engines, are hailed as the heart of power plants. Their main components can be categorized into blades, rotor shafts, cylinders, partition plates, steam seals, etc. Blades are the critical components of steam turbines—among the most intricate and vital parts, and also the most numerous type of component within the turbine.
Steam turbine blades operate under extreme conditions—enduring combined effects of high temperature, high pressure, centrifugal forces, corrosion, and vibration. This necessitates exceptional strength, superior high-temperature mechanical properties, and corrosion resistance. Blade materials typically include difficult-to-machine alloys such as high-strength stainless steels, superalloys, and titanium alloys. With the turbine industry currently at peak production capacity, Industrial chains are prioritizing efficiency gains, demanding cutting tools with high machining efficiency, extended longevity, and multi-material versatility—imposing increasingly stringent requirements on tooling performance.
