Machining plays a key role in the manufacture of turbine blades. Through machining, turbine blades can be precisely shaped, trimmed and detailed to achieve the size, shape and surface quality required by the design.
During the machining process, various advanced processing technologies and equipment, such as CNC machining, are used to ensure the accuracy and efficiency of the processing. The blade profile, edge, installation location, etc. are carefully processed to ensure that they can operate efficiently when the turbine is working, while having good aerodynamic performance and mechanical strength.
