fter the compression spring is used for a period of time, a certain error will occur due to deformation. What to do at this time? Rest assured, the following editor of Hongsheng Spring will teach you how to correct the compression spring:

In fact, for helical compression springs, after the end faces are ground, if the free height, perpendicularity, pitch and outer diameter of the spring do not reach the specified deviation value, correction processing is often required.

Calibration operations are now generally basically in manual or semi-manual operation. Commonly used tools are: when the spring wire is greater than 4mm, tools such as a hand press, slitter, punch, etc. are generally used. If the wire in the spring is less than 4mm, we usually use special tools, pliers, hammers and other tools with wedge-shaped cutting edges. The correction process is to use these tools to locally plastically deform the spring to obtain a pattern of the desired size.
