What is the need for heat treatment in precision gear processing? What is the subsequent heat treatment method for precision gears? Let's take a look.
In order to ensure the required precision in the subsequent processing steps of the precision gear, the hardness of the material needs to be increased, so the heat treatment process is arranged after the blanking and after the roughing.
The auxiliary process is arranged in the finishing stage to ensure that each size does not damage the main processing surface, including the inspection process, the phosphating process, and the cleaning process.
20CrMnTi is a low-carbon alloy. It is normalized to improve the machining performance and reduce the residual stress in the precision gear.
The normalizing treatment should be arranged after the fur forging is completed, before the roughing. During the working process, the precision gear is required to be hard and the core is tough. Therefore, carburizing and quenching are used. In order to ensure the uniform carburization depth, the carburizing is arranged before the grinding process.
