Titanium impeller

The machining process of a titanium alloy impeller involves several critical steps to ensure precision and performance. Initially, the raw titanium alloy material is selected based on the required mechanical properties and corrosion resistance. The process begins with rough machining, where the basic shape of the impeller is formed using CNC milling or turning. Due to titanium's high strength and low thermal conductivity, specialized cutting tools and coolants are employed to manage heat and prevent tool wear. Next, semi-finishing is performed to refine the impeller's geometry, including the blades and hub. This stage requires high precision to achieve the desired aerodynamic profile. Finishing follows, where the surfaces are meticulously machined to meet tight tolerances and smooth finishes, essential for optimal fluid dynamics. Throughout the process, quality control is paramount. Advanced metrology tools, such as CMM (Coordinate Measuring Machines), are used to verify dimensional accuracy and surface integrity. Finally, post-processing treatments, such as stress relieving and surface coating, may be applied to enhance durability and performance. The entire process demands expertise in handling titanium's unique properties to produce a high-quality, reliable impeller.
