About Machining Deformation
For precision machining of parts, due to the complexity of its structure, the special nature of the material, will inevitably encounter various problems of stress and deformation engineer unpredictable during processing, text-Machinery Plant focused on precision parts machining, and continue through the actual processing summarize experience, mainly in the following situations:
1, tube-type material when cut will produce bending deformation, especially stainless steel material;
2, will produce stress and deformation of the center position when the part was hollowed out;
3, bakelite, POM / PE / PEEK and other plastic-like material in the processing due to the excessive cutting or machining high temperature deformation;
4, welding steel without proper scientific aging treatment;
5, after the process due to improper setting process generated machining distortion;
In order to avoid the above situation appears to improve the precision of the workpiece, Man Shun Machinery Factory technicians concluded the following experience:
1, For custom materials, insulating materials for proper scientific aging treatment;
2, the complex structure parts processing, need to take into account the stress between each step, to set scientific and reasonable process;
3, POM / PE / PEEK material processing, the need to take into account the special nature of the material, set the appropriate allowance, a "small number" principle slow process;
4, for surface processing needs design suitable fixture, balanced distribution of the workpiece clamping force in order to reduce the amount of deformation;、
