How to repair the crack of stainless steel bending tool?
The specific repair of tool crack depends on the size of the crack.
If the crack is relatively shallow, use a flat grinding to grind off one layer of the whole blade edge.
However, if the crack is deep and the grinding method is still used, whether the strength of the remaining part of the blade edge can withstand the bending pressure is a problem.
However, the hardness of the material for repair welding is not necessarily the same as that of the original material, which may affect the service performance of the tool.
