At present, my country's aviation manufacturing industry is developing at a high speed. With the continuous development of this industry, the demand for aero-engines will also greatly increase. For some parts of aero generators, we have been insisting on "returning" customers with high quality, high configuration and high service. Among them, blisk processing is a typical example. This project looks simple, but it is actually complicated.

Blisks are generally used in the aviation industry and are important components in aero-engines, which can effectively improve the practicability and reliability of generators. However, during the machining process, the blades are prone to micro-deformation during machining and the radial impact on the tool is very large, which affects the surface machining quality of the blisk blades. So what do we need to pay attention to in the process of improving quality and efficiency? Next, let me give you a brief introduction.

1. In the process of processing, the combination of rake angle and relief angle should be rationalized to increase the cutting force, which can effectively reduce the cutting heat.

2. For the selection of base material and coating, we must have a basis and pertinence, and we cannot make a blind choice. If the processing effect is not good, it is easy to reduce the abrasive wear of the tool and improve the service life.

3. In terms of structure, it has a unique unequal blade structure, which must be stable and reduce vibration during cutting.
