Compression Spring Squareness | Newcomb Spring Manufacturer

Larger spring indexes (D/d) reduce the effect that grinding has on squareness. Springs that are closed only are generally not "as square" as springs with ground ends. To measure the squareness of a compression spring it is necessary to place the spring on a flat plate with a post or back plate set at a 90-degree angle (see illustration). Keep ...

To adjust the squareness we adjust the height of one of these islands by wrapping the blade of the square in sand paper and grinding it down. Which island you target depends on which direction the blade of the square needs to move. Only grind a little bit at a time and test for squareness frequently.
