Because the turbine blade profile is precision cast with no machining allowance. In view of the complicated internal and external structure of the turbine blade, the process and process requirements of the turbine blade in the casting process are to a very high standard. Due to the particularity of the precision casting process, the dimensional tolerance and shape tolerance of each blade cast are very It is difficult to be consistent. In this way, each blade can have extreme phenomena within the required tolerance range, and the tolerance range of each blade is inconsistent, which makes it difficult for subsequent processing.

It is also one of the important factors that make turbine blades difficult to process. In order to solve the problem that turbine blades are difficult to process, Hanfei has developed an intelligent manufacturing system for aero-engine turbine blades for the turbine blades with no margin precision casting process.
