METHOD OF GRINDING SPRING ENDS AND SPRING END GRINDING MACHINE

摘要

A method of grinding spring ends of helical compression springs is carried out using a numerically controlled spring end grinding machine having a grinding unit, a loading unit and a control unit that controls the loading unit and the grinding unit. The grinding unit has a pair of grinding wheels including two rotatable grinding wheels between which is formed a grinding space. The loading unit has at least one loading plate substantially rotatable axially parallel to the grinding wheels and has a plurality of out-of-axis spring receptacles, each to receive a helical compression spring.
