The precision cnc machining centre believes that the following reasons are generated.
1. the role of internal forces lead to parts processing deformation.
2. heat treatment processing is easy to produce deformation problems, for example, such as some sheet-like mechanical parts, due to its long diameter is very large, in the heat treatment is easy to appear after the phenomenon of straw hat bending. And there are some such as the operator's professional knowledge is not solid enough, not much understanding of the structural nature of its parts, but also to a certain extent will increase the occurrence of parts deformation.
3. external factors lead to deformation, such as machine tools and fixtures are not flat, do not understand the nature of the material, the processing of the parts of the positioning is not reasonable, cutting force storage, etc. will cause parts elastic deformation.
