Points to note during heat treatment and grinding of high-grade springs and causes of strain generation.
Reproduction of Private Spring Preparatory School Lecture 60: Sometimes the spring surface may soften due to grinding heat, leading to breakage!
The stiffness of a spring is not strictly defined within a certain range. In some cases, it can be even harder. For types like leaf springs or disc springs, the spring stiffness can be increased to nearly 500 on the Brinell hardness scale. It is common to grind the surface of such springs after heat treatment, as using them with the heat-treated surface intact is very dangerous and not permissible. Now, even with such high-quality springs, there are unexpected cases of breakage, which are often due to mistakes during grinding. *For more detailed information, please refer to the PDF.
