Why is spring grinding head:

In order to guarantee the verticality of the helical compression spring, and the two supporting ring end face to keep in touch with other parts, reduce the deflection and ensure that the host (or zero, parts). Two end face of the helical compression spring generally are conducted to grinding, the grinding process is usually called spring. Mill spring to roughly three kinds of operation mode: manual grinding automatic, semi-automatic grinding and grinding.

Compression spring is usually the end of grinding head in order to increase operation life and to allow vertical bearing surface in spring. Grinding also increases the number of effective diameter of wire coil can be in a given volume of space, this can lead to higher load, or a lower stress.
