In order to ensure the perpendicularity of the helical compression spring, and make the two bearing ring end face and other parts to maintain contact, reduce deflection and ensure that the host (or zero, parts) of the characteristics. Nantong Excellence Spring tells you that the two end surfaces of the helical compression spring are generally grinding process, this process is usually called grinding spring. Grinding spring roughly three kinds of operation: manual grinding, semi-automatic grinding and automatic grinding.
The ends of compression springs are usually ground to increase the operational life and to allow the spring to be perpendicular to the load surface. Grinding also increases the number of active coils of wire diameter available in a given volume of space, which may result in higher loads, or lower stresses. As a modern manufacturer of compression springs, our facility is equipped with a wide variety of equipment - from hand-operated automated, high-speed vertical spindles, to disc grinders for grinding tools.
