The importance of spring calibration process

　　Although the spring is a small part in the entire manufacturing industry, its role is by no means small. Whether it is machinery manufacturing, industrial manufacturing, etc., springs are inseparable. As one of the basic parts, in order to make the spring have better quality, Shenzhen spring manufacturers generally do it by means of calibration.

　　The spring is the basic part that uses elasticity to work. It is generally made of steel materials. Empty to control the movement of machinery, buffer, vibration, can store energy or measure the size of the force. Widely used in machinery, instruments, etc. The application field involves almost all fields of the national economy. The calibration of the spring is also one of the commonly used processes in the spring production process. The calibration work is mainly divided into these three steps:

　　1. Outer diameter. Generally, the outer diameter of the coil spring can be guaranteed to be biased, but the winding ratio of the spring is too large and the tolerance of the outer diameter of the spring is very strict, so the outer diameter needs a certain correction.

　　2. Pitch and height. The pitch is the main criterion for acceptance. If the free height of the spring cannot be guaranteed, the calibration method can be used to adjust it.

　　3. Verticality. In order for the spring to meet the requirements of high-precision verticality, the verticality and accuracy can be improved by correction under the premise that the wear cannot be guaranteed.
