The opposite spring manufacturer corrects labor intensity high, laborious hours, increased the manufacturing cost. Therefore, measures can be taken from the following aspects to reduce or cancel the calibration process.

1 in order to ensure the main performance of the opposite spring manufacturers under the premise, in the design of perpendicularity, pitch uniformity and other indicators as far as possible not to put forward excessively high requirements.

2. Improve the uniformity and stability of mechanical properties of materials of the opposite spring manufacturers, especially the opposite spring manufacturers of materials tensile strength fluctuation range should be as small as possible.

3. Improve the precision of spring coil. Make the opposite spring manufacturers at both ends of the spiral Angle, and uniform ring, uniform pitch, free height control within a certain range

4. Improve the precision of grinding spring. So that the opposite spring manufacturers of perpendicularity to meet the requirements of the design.
