What are the causes of deformation and improvement measures in parts processing？

In the parts processing industry, the most taboo problem is the deformation of parts, once it appears, the consequences will be unimaginable, affecting the economic benefits of enterprises, and causing a series of safety problems, making enterprises nervous. Then what is the cause of the problem of parts deformation? What can be done to improve it?
The main points are as follows:
1. The internal force causes the machining accuracy of parts to change. Technical workers all know that during processing, the parts are jammed by the three claws of the lathe, to ensure that the force is stable when the parts are processed, and over time, it will cause the lathe chuck to loose, making the force of the parts shrink, and there will be deformation. 2, heat treatment processing is easy to produce deformation. When processing some thin and small parts, it is generally necessary to heat treat them first. At this time, if the technical personnel's professional knowledge is not solid, they can not understand the structural performance of these parts well, it is easy to make the parts bend.
3, the external force caused by parts processing elastic deformation. In the processing of parts, lathes and fixtures are often used, when the two are not smooth, it will appear in the fixed parts when the force is not uniform, the force is small on the side will produce deformation.
Improvement Measures:
First, after the parts are heat treated and naturally deformed, professional cutting tools are used to trim them to ensure the perfection of the parts.
Second, carry out technological innovation to increase the stiffness of parts.
Technicians need to improve technology, increase innovation, choose the appropriate heat treatment method, change the stiffness of the parts, so that the parts are not easy to deformation.
