Technical Field
[0001] This utility model relates to the field of spring processing technology, specifically to a spring end face grinding device for spring processing. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. It is a part made of elastic material that deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a spring and is generally made of spring steel. There are many types of springs. According to their shape, the main types are helical springs, spiral springs, leaf springs, and special-shaped springs.
[0003] The patent CN214264957U discloses a double-end grinding device for spring processing. This patent discloses a technical solution to improve grinding efficiency and solves the problem that existing grinding devices are not convenient for grinding both ends of the spring at the same time.
