CNC Machining

CNC Machining is an important step in creating a titanium flange that meets the design requirements from the forged titanium blank. CNC Machining includes turning, drilling, milling, etc. Turning is mainly used to process the outer diameter, inner diameter, sealing surface, etc. of titanium flanges. Through the rotation of the lathe and the feed movement of the tool, the dimensional accuracy and surface roughness are accurately controlled. Drilling is to create bolt holes for connection on the titanium flange, and the position accuracy and verticality of the holes need to be guaranteed. Milling is used to create some special shapes and structures of flanges, such as flanges, grooves, etc.

Heat Treatment

Heat treatment is an important means to improve the performance of titanium flanges. Heat treatment improves the structure and performance of titanium flanges. Annealing can eliminate the residual stress generated in forging and CNC machining, reduce hardness, and improve its plasticity and toughness. Normalizing refines the grains, improves the strength and toughness of the material, and improves its comprehensive mechanical properties. Quenching and tempering further improve the hardness and strength of titanium flanges to meet some working conditions with high requirements for mechanical properties.

Surface Treatment

Surface treatment is of great significance for improving the corrosion resistance and appearance quality of titanium flanges. Common surface treatment methods include pickling, passivation, electroplating, etc. Pickling can remove impurities such as oxide scale and oil stains on the surface of titanium flanges to improve their corrosion resistance. Passivation is to form a dense oxide film on the surface of titanium flanges to further enhance their corrosion resistance. Electroplating can plate a layer of other metals such as nickel, chromium, etc. on the surface of titanium flanges, which can not only improve its corrosion resistance, but also improve its appearance.
