Precision machining technology heat treatment process
With the development of aerospace, industry, microelectronics industry, modern and bioengineering technology, the demand for / precision mechanical parts (feature size in the micron to millimeter level) is increasingly urgent. Its structure and shape of the specificity of the parts material diversity, size and surface quality of the accuracy of the good to become a high-precision mechanical parts and their micro devices and equipment, the obvious characteristics of the use of functionality, material properties, structural shape, sex and other aspects of the requirements are also increasingly high.
With the rapid development of modern precision machining, precision machining technology fast development, slowly emerged a lot of precision machining technology methods, such as micro-precision machining technology, fast forming technology, ultra-processing technology.
In the appropriate time in the precision machining process insert heat treatment, can make the cold, hot process with good, to avoid deformation due to heat treatment. The arrangement of heat treatment, according to the purpose of heat treatment, generally can be divided into:
1, the purpose of the preparatory heat treatment is to remove the internal stresses generated during the manufacture of blanks, improve the cutting performance of metal materials, for the preparation of the later heat treatment. Belong to the preparatory heat treatment of tempering, annealing, normalizing, etc., generally arranged in the roughing before, after. Arranged before roughing, can improve the cutting performance of the material; arranged after roughing, is conducive to the removal of residual internal stress.
