In this video, XINGAONAI Group shows the heat-treatment operation performed on a hammer shaft bore during component manufacturing. Controlled heating helps improve hardness and wear resistance around this critical contact area, allowing the component to better withstand repeated impact and operating loads.
Temperature control is important because excessive or uneven heating may cause deformation and affect bore accuracy. After heat treatment, the component must be checked before final machining and assembly. This workshop footage demonstrates XINGAONAI’s attention to material processing, dimensional control, and the manufacturing quality of critical crusher components.
