Shenzhen non-standard precision machinery parts processing method to remove residual stress in the non-standard precision machinery parts processing, will encounter all sorts of shape parts, especially in the aluminum products processing will often meet some problems: after completion of each process, not only size have change, also could not reach the requirements of the original shape and position tolerance, investigate its reason, is that the machining
deformation when precision machinery parts processing.
Way to solve such problems, are using multi-channel process, and to go after each procedure, increase the stress of the heat treatment process, this way for machining allowance is not suitable for large workpiece, existing processes, cycle long, and a process with the machining allowance is small to stay, can't guarantee precision machinery parts processing after the completion of the deformation in the normal allowed range, the reason is if the heat treatment process set unreasonable, even guarantees that repeatedly also cannot completely eliminate stress generated by the precision machining process, especially for thin wall aluminum workpiece.
It is well known that the main factors which influence the stability of parts with the size of the residual stress and the stability of the microstructure, such as residual stress in the process of precision machinery parts processing, microstructure is not stable, will lead to macroscopic size generate larger changes, general equipment manufacturing enterprises is difficult to have by changing the microstructure means to improve the stability of the technology and equipment, more feasible to solve such problems is a reasonable method of precision machinery processing craft route and heat treatment.
Since the artificial aging treatment method can't eliminate stress each stage of processing, precision machining of the key is to improve the stress of the heat treatment method, in shenzhen Xavier precision components co. , LTD. , is committed to precision machinery parts processing experience, 16 cold heat circulation processing can be used to stress.
The improved process equipment used by the same route, route of the heat treatment process to cancel the original process, in essence millers before adding hot and cold processing cycles.
