The impeller is a new type of engine, and it is the core component of turbine engines and turbocharged engines. It is widely used in many industries, mainly in energy and power, aerospace, petrochemical, metallurgy and other industries. The impeller is a representative, relatively standard-shaped, typical channel-type complex part. Generally, impeller processing manufacturers will directly affect the efficiency of various engine functions, whether in terms of surface processing methods, processing accuracy, or processing surface quality. Because of this, many manufacturers often encounter many problems during the production process, and they are also very tricky. So what problems are causing manufacturers such headaches? Next, let me briefly introduce it to you.

1. Due to the conditions of its own structure and external cutting forces, vibration marks will occur at the entrance of the flow channel and the upper end of the blade. In order to avoid chatter marks, many manufacturers usually change the sharpness of the tool during the impeller machining process. However, doing so will cause burrs to appear on the inlet and outlet of the flow channel and on the edge of the blade. Therefore, the tool must have sufficient rigidity, chip removal space and appropriate sharpness.

2. The blades are severely twisted and have an obvious tendency to lean back. The processing difficulty of this is relatively high. It is recommended to process the curved surface in sections to reduce the severity of processing distortion.

3. In high-speed operation, in order to prevent vibration and reduce noise, it is necessary to promptly increase the requirements for machine tools and cutting tools. However, the requirements for cutting tools are relatively high, so the difficulty of this problem is relatively high.
